Well corrected for distortion and aberration

The Nikon BR-5 is a stepping ring designed to allow lenses with 62mm front threads to be reversed onto the Nikon BR-2 or BR-2A (not included) which are otherwise compatible only with 52mm threads

with accurate shutter speeds and new light seals

but this is an older style with drilled edges and a spring-loaded detent pin

so compatibility is somewhat limited: it will mount to pre-AI bodies like the F and F2

Canon T50 close-up Well corrected for distortion andThe Canon T50 is a manual focus SLR with auto wind, manual rewind, and automatic exposure and that's it. Wait, no, there's a self timer too. Anyway, no manual controls here. This T50 is in good cosmetic condition, with some surface wear from use and handling. Good shutter and metering.
