The Leica 23mm f/2 ASPH Summicron-T is a moderately wide-angle prime lens designed for the Leica TL and TL2. Key features include:
Built-in autofocus with a manual-override option
Great for portraiture, and street and landscape photography
Excellent subject/background isolation
Six groups, nine elements, and two aspherical surfaces
Leica L Mount. This lens mount offers autofocus capability for the Leica T mirrorless camera; however, it’s not compatible with Leica M-mount cameras.
35mm Equivalent. Providing a 35mm focal length after sensor crop, the 23mm Summicron-TL is a high-quality option for street photography, landscape photography, and portraiture. Its moderately fast f/2 aperture gives you some low-light ability and helps create great subject/background isolation. As mentioned above, this lens has autofocus capability with a manual-override option.
High-Quality Optics. As you’d expect from Leica, the Summicron-TL features high-quality optics. It features six groups, nine elements, and two aspherical surfaces. It’s internal-focusing design keeps the front element in place, allowing unrestricted use of the 52mm filter threads.
