Leica Summarit-M 90mm f/2.5 - Leica M Mount

The Leica Summarit-M 90mm f/2.5 is a compact, lightweight telephoto lens designed for the M-mount system. Introduced as a more accessible alternative to the Summicron and Elmarit lines, it features a four-element spherical design that prioritises portability without compromising on mechanical quality. It is well-suited for portraiture and travel, offering a slightly softer rendering wide open with excellent sharpness and contrast when stopped down. When purchasing a used Summarit-M 90mm, the focus ring should be tested for smooth, consistent resistance across the range. We inspect the front and rear elements for scratches to the coatings, which can be delicate. Internal dust is common but rarely affects image quality; however, we check for any signs of haze or fungal growth. The aperture blades should be free of oil and click firmly into place.
