OM System M.Zuiko Digital 12-40mm f/2.8 PRO II 24-80mm
A constant f/2.8 aperture across the 24-80mm equivalent zoom range pairs with advanced ZERO and Fluorine lens coatings for sharp, high-contrast images in harsh conditions. Its fully weather-sealed, 454g build withstands unpredictable outdoor environments without weighing down a compact Micro Four Thirds kit. This lens is best for portrait and event photographers needing a rugged, fast standard zoom that delivers reliable autofocus and a useful 0.3x close-up magnification.
