Pentax K5 Best Price Check

Pentax K5 DSLR Review: In the past ten years or so I've used and/or owned many digital, film, and digital SLR cameras-  more perhaps than I'd like to count or share. In that time very few cameras truly rise up as my overall favorites. They've come in large and small packages, expensive and inexpensive alike. Price or size has never been a necessary determining factor in a design. I admire cameras of all makes and sizes and prices.

Few of those designs, and I mean very few, have taken ahold of my imagination and photographic spirit the way the Pentax K5 has. This extensive review explains why the Pentax K5 is truly a special camera to me, and why it is my vote for DSLR of the Decade.




Introduction:

Yet another  honest to goodness DSLR review? 1001 Noisy Cameras ought to be pleased about that, right? Anyways, Pentax's K5 is the most recent DSLR to come across my desk, and rounds out my triple header weather proof DSLR review set. Fresh off of writing the K200D and K20D DSLR reviews (other DSLRS of which I own, and have owned in the past), the K5 makes a serious case for its place in my weatherproof DSLR kit along side those camera bodies. Of late, I've outfitted myself with a weatherproof DSLR kit simply because I do not want to miss an opportune moment due to harsh weather conditions- I want to be right out there in them.

Time is fleeting. In my mind there's no time to cancel a photographic assignment or planned outing because the weather doesn't favor the equipment or comfort I seek. Therefore if my equipment is ready to handle the task, I've really got no excuse not to get out in the good stuff and see the world. And that's exactly what the aforementioned Pentax's do best- they're ready to take on the challenge of just about any sort of inclimate weather and do it reliably.

Although I tried to cover as much as possible about the K5 in this review, it's next to impossible to do so without writing a huge book. So I've put down in writing what has come to mind first when using the K5. Now with that said, onward.

K5 Versatility 
Lets first take a look at what type of photographer would best benefit from the K5.  Here I've compiled a list of photographer types and highlight features of the K5 that might be the best consideration for that particular type of photographer or assignment.

K5 Shown here with optional weatherproof vertical/portrait grip

Sports Shooters: Fast continuous AF, 7fps, a 100% accurate viewfinder with very decent magnification, and awesome high ISO image quality make the K5 a real contender for this role. It may not be the best option but certainly the most affordable one and very capable indeed. Three years ago this camera would have been right at the top for a pick at this role.

Street Shooters: It's weatherproof, small and unintimidating, ultra quiet, takes just about any manual focus lens and with a magnification feature, great low and high ISO image quality, excellent viewfinder, discreet, what more can you ask for when shopping for a street camera?

Landscapers: Image quality galore, HDR, multi-exposure raw files, 100% LCD and OVF framing, axis and horizon digital level, Live View, ultra magnification for fine focusing, weatherproof, cold proof, small and packable, excellent battery life, what the heck else do you need from a camera for landscapes?

Portrait Shooters: Again, it's quiet, it has built in wireless flash capabilities with a dedicated flash sync, unitimidating, handles excellent, lots of fast prime lenses available for it (and a few fast zooms), and plenty of resolution for large prints.

Macro Shooters: It's big 3" screen, magnification abilities, focus bracketing, excellent resolution, small body for tight spaces, and flash options make it a wonderful contender.

Outdoorsman/Extreme Photographers: See landscapers section. Add that you can buy very good weather proof optics that are small and sharp for very little money- and my goodness what an IDEAL dslr for this task. Plenty of room in the grip. Buttons are usable with cold weather gloves, its durable, small, and able to withstand extreme elements.

Traveling Journalists: A small quiet DSLR with excellent high ISO capability supported by a vast number of excellent high quality small yet fast prime lenses (Limited Series). Unintimidating and feature packed to handle a multitude of shooting environments many journalists face- I simply can't think of a better DSLR for this task.


The Beginner: The K5 may be more expensive than entry level DSLRS, but you can operate it like a beginners camera for as long as you like- until you are ready to start advancing your photographic skills. The K5 is an excellent platform to grow into, and likely you'll find it difficult to ever reach the full potential of what the K5 is capable of. Great long term investment, buy one camera and forget it. Start shooting like crazy.

Pentax Lineup Cross Comparison 

K200D vs K20D vs K5 (The Three Amigos!)
Pentax K5 Best Price Check

Lets take a look at how the K5 compares to the other Pentax DSLRS I have in my tool chest. I've picked all three of these cameras for various reasons and all will get rotating photographic duty, especially with fall and winter weather coming to California very soon. All three of these cameras have extensive weather sealing and two of them are almost obscenely affordable on the used market. I like them all for their strong points, but there has to be one that stands out the most.

   

Size comparisons of The Three Amigos with different Pentax lenses. Look out for a review on the one in the middle soon.

Pentax K200D

First introduced in early 2008. Affordable minimalist DSLR with weatherproof capabilities, go anywhere worry free AA power supply, excellent low ISO CCD image output, small and yet very comfortable with just about any lens. Lightest of the group. When going lite for trail running or day backpacking trips, could be the preferred body. When you want a back to basics experience without a heady menu system or complicated interface, or just feeling sort of retro, this is the camera to bring. Bring it along to take pictures, period.

Pentax K20D

First introduced in early 2008. Best handling DSLR of the group- has some features from both the K200D and K5, kind of the middle man DSLR here. The K20D although older, still has an unique alluring quality about it. Biggest DSLR of the pack but still not too bulky or large for backpacking or trail running if you don't mind additional weight in your pack, or if you use a smaller lens. Still has a minimalist back to basics feel to it, but enough customization and newer style features to tinker with if you get the itch. A well balanced DSLR in this regard- makes it a unique and satisfying camera to shoot with. It has just enough of what you need for most situations to make it a very capable tool. Image quality is excellent for landscapes especially. It'll hold its own for wildlife or action shooting if you need it too. The K20D screams "I can do it, if you let me try." Might be the best overall value at its used price of all three cameras. It all depends on the depth of your needs though.

Pentax K5

First introduced in early 2010. "Q" would build this DSLR for James Bond. The most expensive of the group. It can do everything either camera in this group can do and much more, but it's reliant on a proprietary lithium battery. Smaller than the K20D, but heavier than the K200D. Best image quality by far of the group (less that mystical special K200D CCD factor). Almost every feature can be customized, you could spend hours on downtime relaxing on the couch processing images or videos in the camera after the fact. Bring it into a hurricane, drop it into a sand dune, shoot it out of a 16" Battleship gun, the K5 won't care. Excellent Landscape tool, especially because of its WYSIWYG OVF and LCD composition capabilities- yet there are a plethora more reasons that make it such a good tool for this task. Almost an overwhelming feature set and capable package. Responsive, versatile, Pentax's best overall effort yet. The K5 is the best culmination/combination of what Pentax is good at. It's cute and small, but lookout, it really is a wolf in sheep's clothing. 

The K5 stands out of this pack and is hereby branded- A Jack of all trades, master of sum.

The K5's Remarkable Processing and Image Sensor

 _____________________________________________________________________________

The K5 is equipped with a brand new Prime II image processor and 16.3mp CMOS sensor. Together, they and the engineered firmware make all the beautiful image quality magic happen. After looking over the images I've amassed so far at all ISO sensitivities, I've come away quite impressed.

"The sky is the limit"- that's the thought that repeated itself  when deciding what sensitivity setting I want to use with the K5. I am pleased with the output at all ISO sensitivities, and quite frankly blown away. I believe the K5 is basically worry free to ISO 6400 in terms of image quality, 12800 to 25,600 are totally decent (sometimes for large prints especially monochrome), and beyond 25,600 are usable up to its max ISO of 51,200.

I've seen no banding or bad habits of the sensor at any sensitivity setting, which falls in line with my findings on the A580 DSLR sharing the similar sensor as well. Processing in the camera though, is another big part of the equation wherein the K5 excels.

At the lowest sensitivity I find the K5 is the first camera that I can use to shoot in raw for landscapes in harsh lighting circumstances that retains enough dynamic range that makes HDR near obsolete. You'll need to work your files sometimes, but the shadow detail is phenomenal, even when you "pull" your shadows up greatly.
Even up to ISO 200 I find the K5 will handle most scenes in this fashion quite well. Not too long ago what is possible with the K5 now, was simply impossible.

Next are some samples I've included for this review covering a broad range of ISO sensitivities. Most of these are processed from ACR in Photoshop unless otherwise stated. Each picture has a caption giving some details of the settings, click on the image for a larger size, hit your browsers back button to return to the review.

Trabuco Canyon Landscape ISO 200 18-55mm WR Lens f/8 CTE WB Setting

Old Junker From 60's Hippy Days, Trabuco Canyon ISO 2500 f/8 (Note Low Noise!)

Old Mining Shaft, Trabuco Canyon ISO 6400 f/5.6 (Note color retention/low noise)

Apollo, 55mm SDM ISO 16,000 f/4 (Note the very low light by his pupils!)
Pentax K5 Best Price Check 

Those four samples are just a small looking glass into the capabilities of the K5 image quality wise. All of them were shot without extra care made to using higher ISO values. This is unlike just about every other camera I've used in the past -less the A580, where I've always handled higher sensitivities with extra caution. 

The very last image of Apollo retains excellent detail and was shot in difficult low artificial light. Low light is the real test for a sensor, just about any sensor can perform good at higher ISO's in well lit (especially studio images) scenes. The K5 passes this harsh test with flying colors (while retaining them at the same time!). Here is a shot at ISO 2500 where subtle tones and color are preserved, almost unthinkable for this ISO setting not too long ago, and this is just a Jpeg straight out of camera.

ISO 2,500 AWB, low light (note low grain, wow)

In low ISO's blue sky noise is next to none up to ISO 200, preferably ISO 80. Most landscape photographers I know prefer to use lower ISO's for most images, so this makes the K5 a great choice for them. 

Metering
Compared to other Pentax DSLRS and the older 16 segment metering, the K5's 77 segment metering is simply in another class of performance here. Without question it's one of the more immediately obvious improvements I noticed right away, and continued to notice. There isn't a metering system that I know that is perfect but the K5's, especially compared to its siblings (less the K7), is so much better in this regard I forgive it for the rare brain fart that may occur. Overall I found it to be very reliable, with a slight bias in preserving highlight detail at times which means the occasional bump up in EV value compensation will need to take place.

White Balance

Like the K7 that pioneered a much more accurate auto-white balance, the K5 follows suit doing a much better than the DSLR predecessors of the past. When I do rely on Jpegs, the output is so close to what I'd adjust in raw, I'm perfectly happy with the results. Outdoors or indoors in odd lighting the K5 just seems to handle color issues well.  Stick it in live view and you can watch the K5 make near immediate color adjustments as you pan around the room, or just after you've turned the camera on. 




Far as I can recollect, Ricoh were the first to pioneer this kind of white balance with the GRD III compact, from there, the K7 followed (not because of Ricoh just in time lines of release), and all of Ricoh's cameras since. Pentax have taken a similar route with all of the cameras from the K7 and beyond and should be commended for the giant leap forward. Not all manufacturers have this down!

It's not a perfect system but heads and tails above past cameras and likely good for about 90% of your shots. I'll take that score any day of the week. Odd how Ricoh ended up purchasing Pentax- isn't it?  Match made in heaven? Could be.

*Note about CTE white balance setting. I find this to be the best auto-setting for landscapes that I've found yet, and If I hadn't read most of the K5 manual, I'd never have found it. Apparently this setting is optimized for landscape use, and I can see why.

Handling 

Overall the K5 handles excellent. I'll preface this segment by saying that I think the K20D still handles better overall- at a very slight expense of size and weight. While the K5 is excellent in this category, the K20D is superb (in my mind one notch higher than excellent). The smaller size of the K5 does make for some real estate compromises in comparison but still manages to be a completely competent overall DSLR in this regard. It's comfortable, balanced, weighty and controls are very well placed. It's no wonder the K5 is so similar to the K7 and it's a testament to the K7's original design out of the gate that it largely remains unchanged.

Auto Focusing System- SAFOX IX+

In general I find the K5 to be a very fast and accurate autofocusing DSLR. The lower the light levels the slower the auto focus of course- which is very common in DSLRS, but the K5 like the K20D and K200D before it doesn't seem to want to give up in near dark conditions (and I like that). In bright light, the K5 is one of the fastest focusing DSLRS I've ever used (top 3 for sure), especially when using a lens that is screw driven and utilizes the in-body focusing motor. 



The SDM focusing lenses are quiet and smooth but the focus motors aren't as fast as I'm accustomed to seeing with this type. I'd like to try out some other brands on the Pentax to get a feel. That said, the screw driven lenses are super snappy, and this obviously isn't an issue with the K5 (nor with SDM lenses really, it's not that big of an issue).

The K5 attacks its AF subject quickly, and is tenacious in constant AF mode. The motor in the body works overtime to keep your subject in focus, like a cat following a drawn string on the carpet floor- quick quick quick quick! Micro adjustments happen constantly and frequently, and although it can be a bit loud, I find it accurate after I've made an exposure. If for whatever reason your K5/lens combo doesn't focus accurately, don't worry, the K5 has a micro AF adjustment feature that will automatically identify your lens and save your adjustment settings forever and ever (up to 20 lenses).


Live View CDAF System

The only area I find the K5 to exhibit any hint of struggling is when I'm using live view contrast detect auto focusing (CDAF). Sometimes there's just not enough contrast for the K5 to lock onto in a scene and this is very much normal for this kind of AF system. Using PDAF (phase detect) in live view isn't all that bad and seems to have a higher percentage lock rate. If you don't mind the mirror flip up and down, try it, I like it.




Otherwise, the AF point can be positioned just about anywhere on the screen, when using CDAF find an area with more contrast to use the AF point on, and likely the K5 will lock, and lock accurately. Only on a couple of occasions did a scene trick the K5 into thinking it really had a sharp lock, when in fact it didn't. I don't complain about those kind of results, especially because of the vast improvement I've seen in CDAF technology and how that has found its way into the K5.

My Favorite Two Filters- Cross Processing and Infrared

I'm a big sucker, I like the cross processing look. Occasionally CP can just render a mood that other processing techniques simply can't offer no matter how hard they try. The feeling is difficult for me to describe, but best attributed to my childhood when viewing old photo albums that had pictures from the 1970's. You know the kind? The almost turned orange and near faded look? That doesn't quite fully explain the draw CP has for me though, there is something else to it I really like. Here is a quickie sample I took while driving (don't do that).

Some Church in Rancho Santa Margarita, CP blue/magenta filter, ISO 250

The K5's Infrared Filter isn't so bad either. It's a bit hit and miss when it comes to a real "near IR" look, but when the camera gets it right, it's a lot of fun. I myself shoot with IR cameras (conversions, not Hoya filters) so I know what the real deal should look like. Even though it's not authentic, the look is intriguing and promotes experimentation. Blue skies w/clouds make a nice backdrop if you can get them in your scene. Pentax basically simulates the look of IR by taking the blue channel and making it fully dark, and turns vegetation into a more translucent white (that doesn't always work). Nevertheless it's grainy and it's fun, and that is enough for me to have some fun with. Portraits look really interesting. Try it. Le Sample below.

Just A Tree- IR Filter ISO 80 (My favorite ISO setting for this filter)

Technical Info and Commentary 

Build Quality 

The heart of the K5 (just as the K7 before it) lies in a hybrid magnesium allow body, encasing a stainless steel chassis that's strong enough to take years of heavy photographic use. Pentax clearly overbuilds their cameras. Why isn't the very back panel made of magnesium too? The high level composite type of the back panel isn't chincy plastic, its durable fiber reinforced composite that stays warmer, resists scratches,  and takes bumps and bruises better by being able to flex, unlike metal.




Weather Sealing 

There are a plethora of gaskets and seals on the Pentax K5 that armor it from the elements. In my time with the K5, I've only had one rainy day to test it out but it was quite a day of rain. I wasn't shy about keeping the K5 in the elements while I was warm and dry under my gortex gear and waterproof boots. Prior to that day I've spent time in Hawaii with the K7 in torrential rains and the K7 never budged. Therefore I can attest personally to the level of sealing and dust protection from experience. It flat out works and gives me a sense of calm knowing the elements won't ruin a trip.


Optical Viewfinder

The K5 is equipped with one of the very best optical viewfinders in the high end DSLR category. Specification wise, it's a  full 100% coverage (typical is about 96%), .92x magnification (typical is about .85-.90x) finder that is quite bright via the glass pentaprism. This remains unchanged from the K7. A lot of information is displayed at the bottom of the view, including a tilt horizon indicator (can barely make it out in the image to the left) and full time ISO reading. 11 auto focus points (9 double cross type) will light up red when the subject is in focus within the specific AF area. Four focusing screen types are available.



Control Panel 

The K5 is also equipped with a quick control panel that allows you to make fast adjustments while over a highlighted area. This system is fast and intuitive, very similar to what other manufactures have done as well (Sony Quick-Navi screen, Olympus, etc.). I particularly like this screen for fast access to digital filters and cross processing modes, its much faster than navigating the menu. Distortion controls, HDR control, HDR shadow/highlight correction, extended bracketing, file types/sizes/quality, and SR (shake reduction) are just a thumb twist away from fast changes. 

Digital Horizon Level

Another helpful tool, especially for landscape artists, is the digital horizon level. This version is an improvement over the K7's digital level in that it adds pitch to the equation. This way you can get your horizontal adjustment as well as your pitch correct at the same time. Combine this tool with the automatic geometric distortion correction at the time of shooting, and this will save photographers a lot of time in photoshop. Also if you're an aviation buff, you can mock fly the K5 around your house airplane style like a little kid. Yeah, you know I did it- so what.




Live View

Just about every tool you could want for live view is included with the K5. It uses two kinds of focusing methods- contrast detect and phase detect (with a mirror flip), has face detection, manual focusing magnification on any area of the screen, a live histogram (luminescence only), full EV adjustment range, digital level, normal shooting settings, 3 kinds of  grid overlay screens, and much more. Although contrast detection AF isn't as fast as phase detection, Pentax has done a lot of work making theirs much faster since the introduction of the K7 (do any of you remember the first generation CDAF?).

Quick Market Comparison: K5 vs. A580
Pentax K5 Best Price Check

Another camera which shares a similar sensor as the K5 is the Sony Alpha A580. This is a camera which I've repeatedly announced high praise for, mainly because of its image quality for the price. Currently the A580 goes for about $799.00 Body Only, roughly half of the price of the K5 unless you factor in the current rebate for the K5 of $300.00 off of its $1,499.00 MSRP.

The K5 is even smaller than the Sony A580 but still retains a better grip, which surprised me. Not lighter, but smaller.

For about $500.00 dollars more than the A580 though, the K5 has an impressive upgrade path which included the following: Industry leading weather/dust sealing, a much larger and brighter optical viewfinder, better grip and control surfaces, magnesium and stainless steel build quality, massive customization options, a much quieter shutter/mirror cycle, dedicated AF lamp, battery grip option, longer rated shutter life, top illuminated LCD panel, full metering and autofocus at 7fps (a580 will do 7fps but af and focus are locked), intervalometer, catch-in focus, Jpeg customization options, many art filters, cross processing and reversal film modes, a much more effective and reliable dust removal system, more external controls (dual dials and metering dial for example), a slightly smaller form factor, and many more features that don't come off the top of my head.

Still, the A580 has similar AF speed, image quality, wireless flash as the K5. It bests it with a tilt LCD screen, unique phase detect full live view mode, unique 6 frame image stack multiframe noise reduction/handheld twilight options, lighter weight, and better battery life. To date I believe the A580 represents Sony's best DSLR for the dollar and has been a favorite of mine for nearly a full year now- mainly because of its image quality, stacking features, and tilt LCD.

Both cameras have a 3 frame auto-image aligning/stacking HDR mode, which is not only handy for extreme lighting circumstances but also for low light noise reducing capabilities. When shooting in HDR mode in either camera, noise is reduced by about one full stop because of a 3 image stack in camera. This mode works best on still subjects, and allows for hand hold shooting at high ISO's in very dim circumstances with less noise penalty as a result. Sony's MFNR mode, aligns 6 images, and gives you a 2 stop advantage. I find the image stacking options useful and am glad to see the K5 at least incorporates one of those two types of shooting.

Both will do HD video, but the K5 has more manual options- Sony's advantage is the AVCHD file type which takes less memory to record. Video is not a major concern of mine at all, at this time.

And last but not least, both have a moving image sensor that stabilizes hand held vibrations and movement- which is an advantage for every lens you own.

Other than that I find these two cameras a world apart in how they operate, handle, and what tasks they are best suited for. The A580 will keep up with the K5 in ideal weather circumstances, but add dusty, windy, or rainy environments and the K5 leaves the A580 in the dust. The massive amounts of customization options of the K5 are a strength seldom showcased in reports of the K5. Let me be clear, this is a HUGE part of the K5 experience and it truly sets itself apart from any other manufacturer in this regard. Other manufactures do have customization options (big brands), but for more expense, and never as comprehensive as the K5.

For outdoors, the K5 is an easy no-brainer choice, unless the weather conditions are ideal. Indoors I'll take either, but the K5 has more ISO options, and a dedicated AF assist lamp and much quieter shutter. In low light situations where I need a quiet stealthy camera (when do we ever need a loud camera?), the K5 would win here hands down. Yep it's more expensive but for my personal use, I find the advantages worth the extra cost. Both are excellent cameras for the price however.

As overwhelmed with the K5 as I am, I almost find it shocking that the A580 still impresses me after using the K5. Holding both in your hand tells you a lot about the quality of construction which speaks volumes in favor of the K5, but when comparing image quality on screen or print they are very close to one another- the K5 having a one stop advantage in shadow detail and overall dynamic range. In use, both cameras are just a blast to use and entice creativity backed by solid fast and reliable performance.

My pick if I have to have just one camera? The Pentax K5, price and all.

K5 vs. Mirrorless 

In case you don't know, there's a new kind of camera segment that's been gaining popularity in the photo industry. Most manufacturers are now involved in the mirrorless category which include Sony, Samsung, Pentax, Olympus, Panasonic, and even Nikon finally stumbled into the market with a new model or two recently. 

Fortunately I've also had the opportunity to try many of these models out first hand. Some are much more impressive than others- let me first get that straight. Some are also very tempting for me to use in addition to DSLRS, yet the only way I can justify getting yet another camera system is to be sure there is a place for one in my shooting that is legitimate and not just for play or fun.


Mirrorless cameras are typically more compact than DSLRS which is supposed to be their main selling point. So far though, in having used several different brands and models, the only real mirrorless system I see out there that is really compact is the Pentax Q system. Sony does well the the NEX-3/5 series, but once you add anything but a pancake prime lens to it, the size factor is suddenly not as good, and there are compromises that come with such a system. 

Many of them do not have a built in viewfinder, you'll need to purchase a separate (and often expensive) EVF finder in order to get that eye level view. And when you do attach the finder, there is more compromise in the compact advantages a mirrorless system has inherently. So, all of this got me thinking about the K5 and the small limited lenses that are available for it.


I began to realize that the K5 and a small pancake or limited lens wouldn't be all that much bulkier than any of the popular (or respectable class) Mirrorless cameras. Yet at the very same time, there would be no additional compromises I'd have to make with the K5 because it already has everything I need in a camera. Putting a small lens on the front just makes the K5 a very compact imaging device, and it's really not that much larger than some of the enthusiast level mirrorless cameras out there with a similar lens attached. Check out this photo below when compared to the Canon G12 compact set at a similar focal length, then imagine that most mirrorless cameras are larger than the G12- especially with a lens attached.

The K5 isn't that much larger than the G12, and most  mirrorless cameras w/lens would be larger than the G12.

It'll be a bit heavier than a mirrorless camera, but with that comes a steadier camera, in body image stabilization, a beautiful 100% coverage optical viewfinder, the best APS-C image quality available, and full feature set. So to reiterate, the K5's small form factor again has another advantage here. In a way, the K5 can be as large or small of a system as you'd want it to be. Versatility is an understatement, all without much if any compromise.


This is something to really think about folks. The K5 purchase could do much more for you than you might initially think- it's kind of a stand alone product in this regard. Truly the K5 isn't just a typical DSLR, it really does stand alone in the market as something unique- classing into "DSLRS" although it is one, might be a bit too general. Here we go right back to my buy one camera argument for the K5.


Keep in mind too that there are excellent vintage used manual focus Pentax prime lenses available that would make an excellent companion for a compact outfit. Hmm, something to think about here. No compromises in camera operation, class leading image quality, for near the same size as an enthusiast level mirrorless camera but with much more versatility.

Pentax K5 DSLR Review- Final Conclusion

The Pentax K5 is a stunning representation of Pentax's core strengths and capabilities as a camera manufacturer. Always the camera for the photographer by the photographer kind of company, the K5 incorporates nearly all of Pentax's best attributes and very few of their weaknesses.

Obviously Pentax listened to its users of the K7 and responded. That camera too, had very few weaknesses yet Pentax still managed to improve upon that design with the K5 greatly when many other manufacturers in the same situation might not have given that much effort to do so- and most importantly not needed too.

Unequivocally the K5 is a refined DSLR for the most serious user but its unintimidating exterior seems to politely extend out a hand to new users and say, "Just set me in green mode and I'll take care of you". And that's exactly what the K5 does for serious photographers as well. I couldn't come up with one scenario where I felt the K5 couldn't handle a situation with authority or aplomb.

When you aren't out shooting seriously with it, it's just a cool and fun camera to explore and use. There are so many filters and settings and features that you'll never get bored trying to master any one of them. It's a techy little wonder that manages to push several of my happy buttons simultaneously. It is hard to put down. During the course of writing this review I've stopped several times just because I wanted to shoot with it and it didn't matter what the subject was, a toe, a bowl of mushy cereal, grandmas' old tea kettle, or a lamp. They are all game. I just had to get up and go shoot.

Getting back to being serious, I find the Pentax K5 DSLR to be a well balanced design from any angle you critique it. Not only is it a massive upgrade to the already stellar K7, but I find that all of its features, construction, and image quality all sort of came together like planets aligning in our solar system. Is it perfect? No, of course not. No camera is perfect. Just how close to that ideal the K5 comes though- that is what makes it such a strong camera to recommend to nearly any kind of shooter I can think of.

The K5 in itself is a massive engineering hurdle, I'm not sure buyers really understand the magnitude of engineering the K5 is. To put an enthusiasts dream wish list into a camera, then have it organized in such a way where most things are easy to find and use, have it fit in such a small form factor, and have it perform as responsive as it does- man, you really have to hand it to Pentax's engineers to pull this one off right. I'd give them a high five if I ever meet any of them.

Hurray for the little guy. Go Pentax.

As an all rounder, nobody makes a better DSLR than the Pentax K5 at any price. And in the end that is why I name the Pentax K5 the *DSLR of the Decade.

*Denotes the last 10 years of DSLR history (2001-2010)

As always, be safe and happy shooting.

K5- Pro's and Con's

Here is a quick pro and con list for the short attention span types. All of this praise made finding a con list for the K5 the hardest part of doing this review. All said and done, even with the Con list, the K5 gets the highest praise I've ever bestowed on a DSLR.

Pro's

• Customization Galore
• Highest  Image Quality of any APS-C DSLR (as of writing)
• Images Print Excellent Up to ISO 16,000, Useful Beyond to ISO 51,200
• Excellent Extreme Weather/Environment DSLR
• A Enthusiasts Wish-List Come True
• Generally Fast, Accurate, and Tenacious Low Light Auto Focusing
• SHHHHHhhhhhhhhhhhhh..... It's Ultra Quiet (see con list)
• Small form factor, well balanced weight
• Excellent Large, Comfortable, Secure grip (one handed shooting all day long)
• Handling is excellent for such a small DSLR
• Best Dust Removal/Prevention System of Any DSLR
• 100% Accurate, Large, Bright Optical Viewfinder
• Big LCD Screen (Color/Brightness Customizable)
• Dual Customizable Control Dials
• Stellar Price/Feature Ratio
• Fast Frame Rate (6.9 fps Tested, 7fps claimed)
• Strap Lugs Do Not Interfere With Handling (do not press against pressure points on hand)
• Excellent Live View Options (Fast Contrast Detect AF w/firmware update)
• Several Firmware Updates Enhance Feature Set/Support User
• Excellent Choice For Military/Coast Guard/Government Service Journalists
• User Choice for Noise Reduction On Jpegs 
• Automatic Lens Distortion Correction (for more modern Pentax Lenses)
• Autofocus Fine Tuning (up to 20 lenses)
• Embedded Custom Copyright Information Option
• 4 Customizable Buttons/Dials
• Tilt/Axis Digital Level (tilt level even in the viewfinder!)
• In Camera Image Stabilization (SR)
• Dynamic Range Setting, Auto-Aligning HDR Setting, Multi-Exposure Setting (available for Raw files too!)
• DNG Raw Format or PEF Proprietary Format Available
• Myriad of Filter/Film Simulation Options
• Excellent Buffer (with newest firmware v1.11)
• Quick Adjustment Info Screen (w/full time/date/day display)
• Excellent Timer/Drive Options (remote options especially)
• Dedicated Mirror Up Mode/Bulb Mode (all ISO's now available in this mode due to fw upgrade)
• Excellent Range of EV Control (-5 to +5)
• Enough Bracketing Options To Satisfy Anyone
• HD Video, and External Mic Jack
• 16mp resolution14 Bit Raw Files (for excellent color rendition/prints at very large sizes) 
• GPS Option if you are into that

Con's

• Image processing for HDR shooting can take a bit too long
• Battery life could be a bit better (but is great when you manage it well, which is key)
• Cross Processing should be available for in-camera post processing duties
• AF speed in lower light levels could be a bit faster (but it is tenacious and rarely does not lock on)
• A Flush Mounted, Flip and Twist LCD Would be Better (as long as handling/size isn't compromised)
• In Body AF Motor Can Be Loud (Manual/SDM focusing ensures near silent reputation, see pro list)
• One Card Slot (I just use a 32GB Class 10 card though)
• Flash Sync Speed Could Be Higher To Match Competitors 
• Write times in some shooting modes are pretty slow
• Bottom of camera could use rubber seating around tripod mount (to keep camera secure on tripod/minimize damage to paint/body)
• Bring back the finger grooves in the left side of the body (like the K20 please)
• Swing out doors are better than rubber grommets

K5 ISO 51,200 Gallery 

The K5 is an extraordinary tool for low light shooting, as I've discussed on the review almost ad nauseum, however, I felt that a small gallery showing samples of the capability of the K5 might help to do my words more justice. Tell me what you think on the three samples below! (Processed from Raw in ACR)

Morning Coffee

My Favorite Model!

Pokey, the Handsome Lad!
