Olympus PRO-grade MFT ultra-wide to standard zoom covering 16-50mm equivalent with weather sealing.
The Olympus M.Zuiko Digital ED 8-25mm f/4 PRO launched in 2021 as a unique ultra-wide to standard zoom for Micro Four Thirds, covering 16-50mm equivalent. It fills an unusual niche — wider than a standard zoom but extending past typical ultra-wide range.
Optical quality is excellent — sharp across the frame with well-controlled distortion and chromatic aberration. The constant f/4 aperture maintains consistent exposure throughout the zoom range. PRO designation means weather sealing, freeze-proofing, and premium build quality.
Micro Four Thirds mount with 72mm filter thread. Compact at 411g. Full weather sealing and freeze-proofing to -10°C. Minimum focus distance 23cm. The MSC focus motor is fast and near-silent. L-Fn button on the barrel for customisable controls.
Limited used availability as a specialist lens. Commands a premium due to PRO designation and unique range. Check for dust ingress despite weather sealing. The Olympus 7-14mm f/2.8 PRO is wider and faster. A superb travel and landscape lens for MFT shooters.
