Hey, I bought a whole set of retina lenses before I had a camera to put them on, was going to use an adapter to my EOS.
Except I bought before I researched properly, ended up buying not only the later lenses that can go on other SLRs, but also some of the earlier 'front cell' lenses for earlier cameras.
Rather than just re-sell the lenses, I just bought a camera for them.
Now I have a Retina Reflex S with 35/50/80/80 (yes, I bought two 80mm lenses), and a Retina Reflex IV with 28/35/50/50/135. Wanna buy some more?
At least yours was a better price. I'm putting my money on it is actually borken, but for that price who cares?
