OM SYSTEM M.Zuiko Digital ED 12-40mm f/2.8 PRO II Lens V311030SE000

For event photographers and videographers covering weddings, reportage, or travel, the OM SYSTEM M.Zuiko Digital ED 12-40mm f/2.8 PRO II is a workhorse standard zoom. Its constant f/2.8 aperture delivers consistent exposure across the zoom range, while the weather-sealed construction allows shooting in rain, dust, and freezing temperatures down to -10°C. The lens focuses as close as 20 cm for detailed close-ups, and the ZERO coating suppresses flare and ghosting for clear, high-contrast images.
