Plan B, buy a Summicron 40/2, file the lens mount to take the 35mm framelines and you hav a perfct match it seems. My 40 fits the 35mm framelines spot on, strangest experience taking a photo that fit the framelines.
It will be fine at infinity - but the framelines will be too narrow close up....
Gosh, why can't the M8 just be an SLR? 🙄
