Originally posted by Frosty66 I have been discussing lenses here, sorry about that but I thought this was the correct place for "film era" lenses.
Frosty66, the forum has many sections and layers. The thread you just replied to is in a section about film slr cameras. Lenses are in a different section. You'll find that some of the lens threads cover many brands, especially the "lens club" discussion threads, many of which are devoted to particular focal length (ranges) or even particular third-party brands of lenses, etc, etc, etc. The best thing to do is to explore.
The questions in this thread, just before you popped in, are about where is the best place to post threads about non-Pentax, but Pentax-mount-compatible third party cameras. We are hoping for a thoughtful response to that question.
