So I ended up with a Konica Auto S2 after some scouring around the local shops. It's in fantastic condition, although light seals might need some work and yellow focus thing seems to be off. I tried the "focus at infinity" approach and looks like the images don't line up. I'm taking this as a sign of out-of-calibration focusing thing for the RF. Curious if anyone knows any sort of instruction to adjust the calibration of the focusing piece? At the price I got it, I figure I should just do it myself.
