Leica 50mm f/2 APO-Summicron-M ASPH Update on the Flare Issue

In April, I reported on a damaging flare issue with the Leica 50mm f/2 APO ASPH back in April. As I noted with conviction then: “The results are jaw-dropping, in a bad way”.

I had a few private conversations between then and now. My initial examples were rejected by the experts as not unusual and within the bounds of normal behavior. That this was patently false was obvious, but the M-veil exerts such a strong cognitive committment reality warp that the possibility was not admittable as evidence to most all M users. But the actual facts were 100% accessible to anyone willing to look objectively, which some of my readers did.

I then documented the issue with initial examples, as well as cross checking a variety of other M lenses, and documenting those too in my Guide to Leica. now reports that Leica's CEO Alfred Schopf has acknowledged a flare issue with their flagship 50mm f/2 APO ASPH and that current owners should send their lens to Leica for REPAIR. Which is where mine is, so I hope it comes back with improved behavior.

That's doesn't matter really, but I don’t review lenses and make flippant claims:

In the face of (private) criticism from “experts” who dismissed my findings, I stood my ground and just showed the FACTS. Which is what I do in all my work.
