How Much Is a Used Leica APO-Summicron-M 50mm Worth? (2026 Price Guide)

It depends on how you shoot. The APO is sharper edge to edge wide open, has stronger apochromatic correction with less color fringing, and controls the slight focus shift that the standard six element Summicron shows at close distances. The standard Summicron is smaller, lighter, much cheaper, and still excellent, with a classic drawing many prefer. If you regularly shoot wide open and want maximum corner performance, the APO earns its premium; for general use the standard lens is the value pick.

Because it is a recent lens, the vintage faults of haze and separation are uncommon, so focus on mechanical and rangefinder accuracy: confirm sharp focus wide open where the rangefinder patch aligns, since rangefinder calibration matters at this resolution. Check the front element and built in hood for impact damage, work the aperture for smoothness, and verify the 6-bit code on the rear flange is intact. Original box and papers help resale on a collectible lens.

Yes. It is a fully rangefinder coupled M-mount lens with factory 6-bit coding, so it mounts and is auto identified on every digital M from the M8 onward, with lens corrections and EXIF applied automatically. It also adapts cleanly to the Leica SL bodies and to other mirrorless cameras with an M adapter, where the high resolution rewards careful manual focus and live view magnification.
