How Much Is a Used Leica Summicron-M 90mm Worth? (2026 Price Guide)

The 1980-to-1998 Summicron-M is the more practical choice for everyday use because it is noticeably smaller and lighter than the 1958-to-1980 original, while keeping the f/2 speed and the same gentle classic rendering. The earlier version is bulkier and heavier, so it appeals mainly to those who prefer its older look and finishes. Both are Mandler designs and neither is apochromatic, so expect some color fringing on high-contrast edges wide open.

Check for haze and separation in the cemented element groups, since these older lenses can fog internally with age and storage. Work the focus from infinity to the close 1 meter limit and confirm it is smooth without grit or stiffness, as the long telephoto throw shows up any dried lubricant. Inspect the aperture blades for oil, and confirm the rangefinder cam is intact and uncorroded so focus stays accurate.

Yes, both versions mount and focus on digital M cameras, but they were made before factory 6-bit coding, so the body will not auto-identify the lens. You can have a lens 6-bit coded or select the matching profile manually in the menu if you want lens data in the EXIF. The f/2 maximum aperture and bright finder frame make it one of the easier 90mm focal lengths to focus accurately on a rangefinder.

The <a href="/price-guide/apo-summicron-m-90/">APO-Summicron-M 90mm ASPH</a> is sharper wide open and effectively free of color fringing thanks to its apochromatic design, so it is the technically superior optic. The pre-APO Summicron gives a softer, more classic look that many prefer for portraits, and it sells for considerably less. If you want clinical resolution choose the APO, and if you want vintage character at lower cost the pre-APO is the value pick.
