The Leica Summarit-M 35mm f/2.5 is a compact wide-angle manual focus lens designed for Leica M-mount rangefinder cameras. Featuring a traditional six-element, four-group spherical optical design with a nine-bladed circular aperture, this lens delivers the outstanding image quality Leica is renowned for whilst maintaining an exceptionally small and lightweight form factor. With its f/2.5 maximum aperture, 0.8 metre minimum focus distance, and E39 filter thread, the Summarit-M 35mm is an excellent all-rounder for everything from portraiture to landscapes. The lens includes 6-bit digital coding for compatibility with Leica M8 and later digital cameras, allowing for automatic lens identification and optional software-based vignetting correction. A genuine alternative to more expensive Summicron optics, this beloved lens was in production from 2007 to 2014 and remains a popular choice amongst Leica rangefinder enthusiasts worldwide.
