Rolling review for the LEICA M-APO Summicron 35/2 ASPH, will evolve over many weeks. This is not a review written with the lens in hand for a short period of time. I am using the M-APO 35/2 ASPH. on the Leica M10-p Safari, M10 standard, M9Monochrom as well as a few Film bodies such as the M2, M5 and the M7. Yes of course, also on the Leica SL2S.
