High quality gear. I've only found them on Ebay for sale and they will come direct from China to anywhere in the world. I own three Tenpa magnifiers. Two are the same model for different mounts (Pentax and Minolta), and yesterday arrived my 1.22X Tenpa magnifier for my 7D. It also works very well on my Maxxum 9 film camera- and can you imagine the Maxxum 9's viewfinder being magnified 1.22x without vignetting in the corners?!
