Leica's non-APO 35mm f/2 for L-Mount — premium optics without full apochromatic correction.
The Leica Summicron-SL 35mm f/2 ASPH. is Leica's standard (non-APO) 35mm prime for the L-Mount system. It offers Leica optical quality at a lower price than the APO-Summicron-SL 35mm, trading full apochromatic correction for more accessible pricing.
Optically excellent — sharp from f/2.8 with Leica's characteristic rendering. The Summicron designation means f/2 maximum aperture. Not APO-corrected like its sibling, so some residual chromatic aberration is visible at maximum aperture — negligible for most uses.
L-Mount with 67mm filter thread. Approximately 700g. Full weather sealing. Metal construction. Minimum focus distance 30cm. Leica's dual-synchro-drive AF system. L-Mount Alliance compatible with Panasonic and Sigma bodies.
Available used at professional prices. The APO-Summicron-SL 35mm f/2 is optically superior but much more expensive. The Sigma 35mm f/1.4 DG DN Art offers similar performance for much less. For Leica SL system owners wanting a quality 35mm at less than APO prices.
