OM SYSTEM M.Zuiko Digital ED 75-300mm f/4.8-6.7 II Lens

The OM SYSTEM M.Zuiko Digital ED 75-300mm f/4.8-6.7 II Lens is a versatile and relatively compact super-telephoto zoom for Micro Four Thirds mirrorless cameras, delivering a 150-600mm full-frame-equivalent focal range that provides excellent portability and outstanding image quality for an affordable price. It’s well suited to wildlife, sports, and action photography where photographers need to reach distant subjects with sharp detail.

Optically, the lens is built from 18 elements in 13 groups, including one Super ED (Extra-low Dispersion) element, two additional ED elements, and three HR (High Refractive Index) elements, controlling both chromatic and spherical aberrations for a high degree of clarity and sharpness throughout the zoom range. OM System’s ZERO (Zuiko Extra-low Reflection Optical) coating is applied to minimize lens flare and ghosting, maintaining rich color fidelity and improved contrast when shooting in strong or backlit lighting conditions. A rounded 7-blade diaphragm contributes to natural background blurring.

Autofocus uses an inner focusing design with a screw-drive mechanism, paired with Olympus/OM System’s MSC (Movie & Still Compatible) autofocus system for fast, accurate focus acquisition, even on fast-moving subjects. The lens has a minimum focusing distance of 0.9m (at 75mm), yielding a maximum magnification of 0.18x on Micro Four Thirds sensors (0.36x 35mm-equivalent), allowing for stunning close-up shots with remarkable clarity in addition to standard telephoto work.

Build quality is lightweight for its reach, measuring just over 4.5 inches long and weighing only 423g (15 oz.), with a 69mm diameter by 116.5mm length. It accepts a 58mm filter thread. The lens does not include image stabilization of its own, relying instead on in-body stabilization on compatible camera bodies, and is not weather-sealed.

As a Micro Four Thirds-specific lens, the M.Zuiko Digital ED 75-300mm f/4.8-6.7 II is designed exclusively for Micro Four Thirds mirrorless cameras from OM System/Olympus, Panasonic, and other Micro Four Thirds alliance manufacturers.
