Yesterday, while down at our local camera store shopping for a strap for my new M3, I was shown a lens that is susposed to be compatible (according to the guy behind the counter) with my M3. This is a COSMICAR 1:3.5 135MM lens made by the Ichizuka Opt. Co. It has a screw mount, but I was told a baynet adaptor could be obtained. It's about the right size and appears to be a very well made lens. Does anyone know about this lens? Are these guys for real? Thanks for your comments.
