Olympus's compact OM wide prime — 35mm f/2.8 with G.Zuiko designation.
The Olympus G.Zuiko 35mm f/2.8 is a compact wide-angle prime for the Olympus OM system. The G designation indicates the specific optical formula generation. The 35mm provides useful wide perspective on 35mm film.
Optically good — sharp from f/5.6 with the 35mm providing a useful wide-angle perspective. The OM system's compact design philosophy means this is a remarkably small 35mm. G.Zuiko optics.
Olympus OM mount with 49mm filter thread. Very compact — OM miniaturisation. Manual focus and aperture. The G.Zuiko designation predates the later E.Zuiko and other formula designations.
Available used very cheaply. The 35mm f/2 is faster and more desirable. The f/2.8 is more compact and affordable. Adapts to mirrorless cameras via OM adapters. For budget OM wide-angle needs.
