Description — Olympus ED 25mm f/1.2
The Olympus M.Zuiko Digital ED 25mm f/1.2 PRO is a prime lens designed for Micro Four Thirds mirrorless cameras, featuring a Micro Four Thirds native mount for seamless body integration. The standout specification is its f/1.2 maximum aperture — one of the widest available in the MFT ecosystem — which opens up creative possibilities for background separation and shooting in lower light conditions. The 25mm fixed focal length places it firmly in standard territory, making it a natural fit for portraiture, documentary, and general-purpose photography.
Both autofocus and manual focus are supported, giving photographers the option to work in whichever mode suits the moment. A 62mm filter thread sits at the front of the lens, compatible with a broad range of screw-on filter options. The lens weighs 410g, a figure that reflects its fast maximum aperture and professional construction.
It carries no built-in image stabilization, so photographers who depend on optical stabilization will need a camera body that provides it internally.
