The Olympus M.Zuiko Digital 25mm f/1.8 lens is a fast aperture 50mm equivalent prime lens for micro four thirds (MFT) cameras. The lens’s 50mm equivalent focal length makes the lens ideal for portraiture, product and event photography; while a fast maximum aperture of f/1.8 enables users to shoot sharp images handheld in almost any light, or control depth of field to emphasise their subject.
