Olympus's compact 80mm prime for the OM system — a moderate telephoto for portraits.
The Olympus Zuiko 80mm f/4 Auto is a compact moderate telephoto prime for the Olympus OM mount system. At 80mm, it provides a classic short telephoto perspective ideal for portraiture — slightly shorter than the more common 85mm and 100mm portrait primes. The f/4 aperture is modest but adequate for the focal length.
Optical performance is good. Sharpness is very good when stopped down and decent at f/4. The Zuiko optical design delivers the clean, contrasty rendering the OM system is known for. The 80mm focal length provides pleasant portrait compression. Bokeh is acceptable at wider apertures. Multi-coating provides good flare resistance.
Olympus OM mount, manual focus. Filter thread is 49mm — matching most OM system lenses. Weight is approximately 260 grams — very compact. Build quality is excellent with the precision metal construction typical of Zuiko lenses. The Auto designation indicates automatic diaphragm operation. Compatible with all OM-mount cameras and mirrorless adapters.
Available on the used market at moderate prices. Check for smooth focus and clean optics. A compact portrait lens for OM system shooters. The 80mm focal length is slightly unusual — the 85mm f/2 and 100mm f/2.8 are more popular OM portrait options. Adapts well to mirrorless where it becomes a 160mm f/4 on MFT.
