Over the past few years I seem to have accumulated some Exakta cameras and lenses. In fact, my first SLR was an Exakta Exa 1a, back in 1974. That camera, though primitive compared to the standards of the day, taught me a lot about photography and served me for a number of years. I sold it quite a while ago, and a few years ago, acquired another Exa. I don't use them all that much, but they are interesting and somewhat peculiar SLRs. You can read a lot more about Exkata cameras on the Exaktaphile's web pages.
I was recently looking through a box of miscellaneus adapters and found a peculiar little lens adapter from Minolta - the "E adapter". Ha! An Exakta lens adapter for Minolta cameras. That was rather surprising, but since I have an M42 mount to Minolta, I guess it makes sense. There were a lot of decent lenses made for Exaktas (and Topcons that used the Exakta mount at one point), and putting them on a more modern camera body makes sense. I got out my Minolta X-700 (a fantastic manual camera, in my opinion), and put on the adpapter. I then attached one of my Exakta lenses, a Zeiss Jena Tessar, and I had a 56 year old lens on my camera, and I could shoot in aperture prioity if I wished. Cool. Now I'll goof around with these things and will post some images of my results later.
As much of a Nikon lover as I am... their mount pretty much is Nikon or nothing. So, it's fun to able to play around with other permutations of lenses and cameras. OK, so you Canon Eos people have had all kinds of adapters for years.
Here are some images of the gear:
