Leica Summarit-M 50mm f/2.4 - Leica M Mount

The Leica Summarit-M 50mm f/2.4 is the updated version of the original f/2.5 model, featuring a revised optical design and a shorter minimum focusing distance of 0.8 metres. This standard prime is noted for its compact size and high-contrast rendering. It uses spherical lens elements to provide a traditional look, making it a reliable choice for general-purpose photography where a smaller footprint is preferred over the larger Summilux or Summicron alternatives. Inspect the lens barrel for any signs of impact, as these lightweight designs can be sensitive to knocks. The aperture ring should have distinct, tactile clicks, and the focus helicoid must move freely without any dry or gritty spots. We check the internal optics for haze, which can sometimes develop in older M-mount lenses, and ensure the 6-bit coding on the mount is intact and readable by digital M bodies.
