Leica APO-Summicron-SL 90mm f/2 ASPH Review

The Leica APO-Summicron-SL 90mm f/2 ASPH is a premium short telephoto prime for the L-mount system. As part of Leica's SL lens lineup, it delivers the apochromatic correction and fast f/2 aperture that define the Summicron-SL series, designed for full-frame mirrorless bodies like the SL2 and SL2-S. At $6,200, it sits at the top of the 85-90mm focal range in terms of price and build quality, targeting professionals and dedicated Leica shooters who prioritize optical excellence and robust construction. The 90mm focal length is versatile for portraiture, detail work, and documentary shooting, offering slightly more reach than traditional 85mm lenses. With no public reviews yet, reception remains to be seen, but the APO-Summicron designation suggests excellent sharpness, minimal chromatic aberration, and smooth bokeh, hallmarks of Leica's flagship glass.
