OM System announced its latest telephoto zoom, the M.Zuiko Digital ED 50-200mm f/2.8 IS Pro. On a Micro Four Thirds body, the lens covers the same field of view as a 100-400mm on full-frame while holding a fast f/2.8 aperture throughout the range. Paired with OM System’s teleconverters, it can stretch all the way to an 800mm equivalent at f/5.6. Weight wise it comes in at 1,075 grams, which makes it far lighter than comparable full-frame options like Canon’s 100-300mm f/2.8, which is more than double the weight.

The lens design includes 21 elements in 13 groups, with special EDA and super ED glass to keep fringing and flare under control. OM System’s updated ZERO II coating further reduces ghosting in tricky light. An internal zoom design helps balance the lens while shooting, and the autofocus system has been tuned for speed, supporting up to 50fps bursts. For close work, it can focus down to 0.78 meters across the zoom range and offers 0.5x magnification on its own, or 1x when paired with the 2x teleconverter.

Stabilisation is another strong point. The lens works with OM System’s 5-axis sync IS to deliver up to seven stops of correction at the long end. Like other Pro-series glass, it has IP53 weather sealing, freeze resistance down to -10°C, and a heat-resistant coating to keep internal temperatures lower in hot conditions. The 50-200mm f/2.8 IS Pro will be available on October 3, 2025, for $3,699.99.
