Originally posted by RioRico My reaction is the same as @excanonfd. That registry difference may limit far-focus to maybe ~3-9m depending on f-stop. Nothing wrong with that, we can always use specialized lenses with limitations that challenge our creativity. I have a few fixed-focus lenses that keep me challenged. I may end up accepting the same limit with my Prakticar 50/2.4 copy.
Meanwhile, I must get off my lazy butt and finish a mod of a Petri CC 35/2.8. The trick with it is to establish aperture control. I just need to jam *one* piece into place... but that piece is in an almost unreachable position. Once that's in place, I'll just glue-on an M42-PK adapter, and wail! Oh yeah, and I must post a thread on my lens mods and adaptations, with pictures. [/me sweats already]
Bonjour Herrn Doctor RioRico,
Thanks (as always) for your input and far-focus seems to be at 3 to 4m range, but haven't test shot too much here ... Close-focus and kids' portraits are the main goal for me with this one.
Please do thread/post photos of your mods, etc. Maybe we could go "quadraphinic" and start a Mod's Frankenlens Club ... Who? Who would join ...
Salut, "Eyegore" - AKA John
