Leica Summilux-TL 35mm f/1.4 ASPH. - Leica L Mount

The Leica Summilux-TL 35mm f/1.4 ASPH. is a high-speed reference lens for the Leica APS-C system, offering a standard 50mm equivalent field of view. Its large f/1.4 aperture provides significant shallow depth of field and excellent low-light performance. The optical design is complex, featuring internal focusing to maintain lens length and aspherical elements to correct for monochromatic and chromatic aberrations, ensuring sharpness even at maximum aperture. Used examples should be checked for the smoothness of the manual focus ring, which is electronically coupled. We test the autofocus speed and accuracy across different lighting conditions. The lens barrel is robust, but the finish can show silvering or bright marks on the edges with heavy use. We also verify that the lens mount is secure and that the electronic pins are clean and free from corrosion.
