Leica APO-Summicron-SL 28mm f/2 ASPH

Leica's most technically advanced wide-angle prime for the SL system — the APO-Summicron-SL 28mm f/2 ASPH applies apochromatic correction to a wide prime, eliminating chromatic aberration to a degree unprecedented in any 28mm lens. The result is outstanding resolution and colour accuracy at every aperture, with a rendering that is simultaneously clinical and three-dimensional. Autofocus is fast and precise for a native L-mount prime. Compatible with Leica SL2, SL3, Lumix S-series, and Sigma L-mount cameras.

GearFrame's Take

The most optically perfect wide-angle prime available for L-mount — APO correction at 28mm eliminates chromatic aberration entirely and sets a new reference point for the system.
