Leica Summilux-M 35mm f/1.4 ASPH. - Leica M Mount

The Summilux-M 35mm f/1.4 ASPH. is a versatile, fast wide-angle lens for the M-mount rangefinder system. It combines a large f/1.4 maximum aperture with aspherical optical elements to provide high performance in low-light conditions while maintaining a relatively compact form factor. This lens is known for its high resolution and distinctive rendering, making it a staple for many reportage and street photographers. When buying used, pay attention to the focus action, which should be smooth and consistent. SDS technicians check for 'focus shift' issues and ensure the rangefinder coupling is accurate. Earlier versions of the ASPH model (pre-FLE) may exhibit slight focus shift when stopping down; later Floating Lens Element (FLE) versions corrected this. Check the aperture ring for distinct, firm clicks and ensure there is no oil on the diaphragm blades.
