Heralding a new standard of M.ZUIKO lenses as the first model in the new
M.ZUIKO PRO category, the M.ZUIKO DIGITAL ED 12‑40mm 1:2.8 PRO lens is
engineered to meet the needs of professional photographers in all
respects. When combined with the OLYMPUS OM‑D, this large‑aperture lens
achieves the reputation of an unbelievably fast AF high‑performance
Its constant, bright aperture value of 2.8 at all focal lengths
(equivalent to 24‑80mm on a 35mm camera), combined with other
sophisticated technologies including an MSC and Manual Focus Clutch
mechanism, deliver high‑grade image creation for a wide range of
photographic styles, regardless of lighting conditions and distance.
The compact and lightweight design also has a dustproof and splashproof
construction compliant with professional use, expanding shooting
capabilities even in the most testing of environments.
