Olympus Zuiko 50mm f/3.5 Auto-Macro - Olympus OM Mount

The Zuiko 50mm f/3.5 is a dedicated macro lens for the Olympus OM system, capable of 1:2 magnification natively and 1:1 with an extension tube. It features a four-element, five-group optical design known for exceptional sharpness and flat-field performance. The lens is physically compact, maintaining the portability typical of the OM system, and excels in document reproduction and close-up nature photography. Second-hand units should be checked for smooth rotation of the long-throw focus helicoid; grease can sometimes dry out, leading to stiff movement. The front element is deeply recessed, which provides natural flare protection, but the internal barrels should still be inspected for dust or haze. SDS verifies that the automatic diaphragm is snappy and free from oil. Given its age, check for any 'creeping' in the focus barrel when pointed downwards.
