I was at a camera show on Sunday and a seller had a box of "camera junk" that he offered to me for $5. I glanced in the box and saw some vintage stuff that I thought I could use for parts and bought it without looking at it further. When I got home I found this at the bottom of the box: It's a Yashica Pentamatic, the first 35mm SLR made by Yashica. It has a bayonet lens mount unique to the Pentamatic cameras and 6 or 7 lenses were made for it (that I know of) from 35mm to 250mm. It's definitely a collectible camera and the lenses are pretty scarce (in the USA anyway). It needed a little cleaning up but it works perfectly and looks nearly mint now. Yashica also made adapters to allow mounting M42 screw mount lenses and Exakta lenses to this camera. Yashica made 2 more Pentamatic models (Pentamatic II and S) and then switched to using the M42 screw-mount for a while until finally switching again to the Yashica/Contax bayonet which is not the same as the earlier Pentamatic bayonet mount. So, I guess I'm gonna have to track down some more lenses for it now.
