Leica Summicron-M 90mm f/2 - Leica M Mount

The Leica Summicron-M 90mm f/2 is a classic mid-telephoto lens for the M-mount system, offering a wide maximum aperture for portraiture and low-light work. This lens is known for its high resolving power and smooth out-of-focus rendering. Several versions exist, including those with a built-in telescopic hood or a removable optical cell for use on a Visoflex. It provides a tight crop that is ideal for isolating subjects. On the used market, focus accuracy is critical for a 90mm f/2 lens; we test this on digital M bodies to ensure the rangefinder coupling is precise. The large internal glass elements should be clear of haze and fungus. Check the telescopic lens hood for smooth operation and ensure it does not slip down when extended. We also inspect the aperture ring for positive clicks and no sign of oil leakage.
