Leica Summilux-M 50mm f/1.4 ASPH

The definitive fast standard prime for the Leica M system — the Summilux-M 50mm f/1.4 ASPH improved dramatically on its predecessor by applying aspherical technology to deliver exceptional sharpness and rendering at all apertures, including wide open. At f/1.4 it produces a signature three-dimensional subject isolation that sets it apart from any other standard prime. The first aspherical element in the front group corrected the coma and astigmatism that limited earlier Summilux designs. Rangefinder-coupled for manual focus on all Leica M-mount cameras.

GearFrame's Take

The fast standard prime that changed what f/1.4 could look like — the Summilux 50mm ASPH delivers a three-dimensional rendering at wide apertures that no other 50mm can replicate.
