Leica has just officially announce the Leica APO-Summicron-SL 50 mm f/2 ASPH lens. It is a bright prime lens designed for full-frame L-mount mirrorless cameras.

- Bright f/2 maximum aperture benefits working in low-light conditions and also affords greater control over depth of field for working with selective focusing techniques.
- Three aspherical elements are used to reduce distortion and spherical aberrations for improved sharpness and accurate rendering.
- Apochromatic design employs anomalous partial dispersion glass to suppress chromatic aberrations throughout the aperture range for increased color accuracy and clarity.
- Multi-layer coatings have been applied to individual elements to suppress surface reflections, flare, and ghosting for increased contrast and color fidelity.
- Dual Syncro Drive stepping motor delivers quick, precise, and near-silent autofocus performance to suit both photo and video applications. This system also avails full-time manual focus override.
