OM System M.Zuiko 45mm f/1.2 PRO 45mm
Combining a 90mm equivalent focal length with an f/1.2 maximum aperture and weather-sealed build, this 410g lens delivers sharp optics via 14 elements including ED and aspherical glass. The MSC autofocus system and manual focus clutch offer fast, tactile control, while the nine-blade diaphragm produces smooth background blur. It’s ideal for portrait photographers on Micro Four Thirds systems who need shallow depth of field and consistent performance in low light.
