50mm · f/2.5
The Leica Summarit-M 50mm f/2.5 is a compact, well-built lens that balances nicely on film and digital M bodies. Optically, it is sharp wide open with modern rendering, but suffers from flare issues, including pink patches and double-image bokeh. Its smooth focus and small size make it ideal for lightweight travel and available-light shooting. However, it is not as flare-resistant as the Summilux ASPH, and some find its aperture ring layout annoying. It suits photographers seeking a compact, affordable Leica 50mm for film or digital when flare is controlled.
