I recently repaired a T3n; I also quite like the lineup from Konica. The glass is cheap (except for the 85mm and 57mm), and there are even adaptors for other lens mounts due to the short flange focal distance. Good luck finding those though, I had to search forever to get a Nikon F adaptor at a reasonable price. Another annoyance is needing to modify the electronics to work with modern silver oxide batteries, since you need a way to drop the voltage by precisely 0.4v. I used two diodes in series.

Here is a middling shot on said T3n, 57mm f1.2, Harman Phoenix 200 push processed two stops. Exposure was for 500 ISO TTL metering, don’t recall what that worked out to.
