Olympus Zuiko Auto-Macro 50mm f/2 - Olympus OM Mount

The Olympus Zuiko Auto-Macro 50mm f/2 is widely regarded as one of the finest lenses produced for the OM system. It is a high-speed macro lens that offers a 1:2 magnification ratio, making it exceptionally versatile for both close-up work and general-purpose photography. The f/2 aperture is unusually bright for a macro lens, providing excellent low-light performance and shallow depth of field control. When sourcing a used 50mm f/2 Macro, the most critical check is for balsam separation in the rear groups, a known issue with this specific model. SDS thoroughly inspects the optics for this clouding, as well as checking the focus mechanism for smoothness over its long travel. The aperture blades must be free from oil to ensure accurate exposures at the high speeds this lens is capable of.
