Leica Summicron-SL 50 f/2 ASPH Reviews

A fine lens with handy size and weight

By Jeffrey

The photos with this on an SL3 have nice contrast and good punchy colors, and the lens has a great size and weight for good handling. Autofocus has tended to be nice and quick in decent light with the SL3, as well. The corners and far edges aren't going to be as good as the heavier, hyper-expensive APO-Summicron-SL, and I expect (expect because the only SL APO I have myself is the 35mm, which is actually technically better than the 50 one) that the 50 APO gives an improvement in microcontrast even in the places this lens is at its best, but this non-APO Summicron is an excellent lens by normal standards. Is it better than the Lumix 50/1.8 with the same optical formula? I can't say for sure, both are good; but I've been enjoying this Leica version and telling myself there might be slightly better optical coatings, quality control and autofocus testing. I like this one's lens hood, as well.

Lovely and Long-Awaited

This Leica 50mm Summicron-SL lens is a lovely, long-awaited prime lens for Leica SL series cameras. Leica's original SL zoom lenses are burdensome to carry and use; and though subsequent APO primes are of course lighter, they're still larger and weigh more than some other-brand zooms. However, the new, non-APO, SL prime series (there's also a 35mm) cut both the size and weight of the APOs by nearly half. One can only be grateful. Naturally, pixel-peepers can assure themselves that this new 50mm lens does not match the extraordinary optical performance of the APO version, but it is still excellent and more than adequate for any normal use. Now what Leica needs to do is to complete its new, non-APO series by adding the 18mm, 24mm, and 85mm models.
