When Leica shipped the Leica 50mm f/2 APO-Summicron-M ASPH with massive flare problems, severe flare issues were evident to me in the first 5 minutes of usage. I stuck to my findings despite aggressive pushback from “experts” unable to use their own eyes. About four months later, Leica stopped the production line for multiple “improvements”. Leica later replaced my sample which was notably improved, if not ideal.
The results are beautiful when the front lens element is shaded. Otherwise, they are total garbage.

In my opinion, the Leica 35mm f/2 APO-Summicron-SL should be recalled, its flare handling problems fixed, and the lens replaced for all customers.
