Leica S-Lenses are in a class of their own. A class of exceptional performance you can experience to the fullest, thanks to your Leica SL and the S-Adapter L. The extraordinarily fast S-Lenses are a testament to 100 years of expertise and experience in lens design and precision manufacturing processes that accept only minimal tolerances. They combine traditional Leica quality with state-of-the-art technology that pushes the limits of the technically possible. S-Lenses already achieve close to maximum performance at maximum aperture, quite independent of the camera-to-subject distance. In every situation, whether in the studio or on location.
