OM System has introduced a new, large-aperture professional telephoto zoom. The OM System M.Zuiko Digital ED 50-200mm F2.8 IS Pro, to give it its full, tortuous name, provides a 100-400mm equivalent range. It also boasts optical image stabilisation and compatibility with teleconverters for even longer reach. As a result, it’s not a replacement for the existing 40-150mm F2.8 Pro, but a higher-spec upgrade.
At a glance:
- $3699 / £2999
- 100-400mm equivalent range
- 7-stop image stabilisation
- 0.5x equivalent magnification
- IP53 weathersealing
- 225.8mm long, 1250g
- Micro Four Thirds mount
Optically, the lens uses a complex design with 21 elements in 13 groups, with plenty of exotic glass employed to maximise edge-to-edge sharpness and minimise colour fringing. Like all the firm’s Pro-series lenses, it’s sealed against dust and water with an IP 53 rating, and is freezeproof to -10°C. Both zooming and focusing are internal.
The optical stabilisation system is rated for at least 5 stops of shake reduction, increasing to 7 stops on high-end bodies like the OM-1 Mark II that fully support Sync IS. Close-up shooting is available too, giving 0.5x equivalent magnification, thanks to a minimum focus distance of just 78cm. Physically, the lens is 225.8mm long and weighs 1250g with its removable tripod mount, which features an Arca-Swiss shoe.
The OM System M.Zuiko Digital ED 50-200mm F2.8 IS PRO is set to be available from 6th October 2025 for £2,999.
We’ve been able to test the lens in advance of its official launch, and it’s very impressive indeed. Read our full review:
