OM System's updated version of the legendary 12-40mm PRO with improved coatings and sealing.
The OM System M.Zuiko Digital ED 12-40mm f/2.8 PRO II is the second generation of Olympus's flagship standard zoom, released in 2022 under the new OM System brand. It provides a 24-80mm equivalent range at a constant f/2.8 in a compact weather-sealed package. The PRO II designation reflects updated coatings and improved weather sealing.
Optical quality is outstanding with excellent sharpness across the frame from wide open, inheriting the original's exceptional performance while adding improved ZERO coating for reduced flare. Autofocus is fast and near-silent. Build is professional-grade with comprehensive dust, splash, and freeze proofing. The lens features a focus clutch mechanism for instant manual focus.
Micro Four Thirds mount only, 62mm filter thread. The original 12-40mm f/2.8 PRO from Olympus remains available at lower used prices and is optically very similar. The Panasonic Leica DG 12-60mm f/2.8-4.0 offers more range but is not constant aperture.
Relatively new with used prices reflecting its recent release. Check the focus clutch mechanism, weather sealing around the mount, and AF motor. The original Olympus 12-40mm f/2.8 PRO at lower prices is the better value proposition unless the updated coatings are important to you.
