Leica's APS-C prime for TL/CL system — 35mm equiv at f/2 with Summicron quality.
The Leica Summicron-TL 23mm f/2 ASPH. is a wide prime for the Leica T system — the APS-C mirrorless series that includes the Leica T, TL, TL2, and CL cameras. The Summicron designation indicates f/2 maximum aperture; ASPH. confirms aspherical elements. Leica TL mount.
f/2 maximum aperture. 23mm focal length (approximately 35mm equivalent on APS-C). ASPH. (aspherical elements). Leica TL mount (APS-C Leica mirrorless system). Autofocus. At approximately 300g.
The Leica TL mount is distinct from the full-frame L-Mount used by the Leica SL/SL2 and L-Mount Alliance bodies. TL-mount lenses cover only the APS-C image circle and are not for L-Mount full-frame bodies. The 23mm provides a 35mm-equivalent field of view well-suited to street and documentary photography on TL/CL cameras.
On the used market the Leica Summicron-TL 23mm f/2 ASPH. is a fast wide prime for the Leica TL-mount system. Condition checks: Leica TL mount contacts, AF response, front element and ASPH. coating for marks. Leica TL mount — APS-C only, not compatible with L-Mount full-frame bodies without an adapter.
