Providing a long zoom range, equivalent to 150-600mm in 35mm format, the M.Zuiko 75-300mm lens has been popular with sports and wildlife photographers. The new M.Zuiko Digital 75-300mm MkII is marginally lighter than its predecessor, although it features a similar optical design with professional-grade optics. Among the 18 elements in 13 groups are a Super ED (Extra-low Dispersion) lens element, and two ED lenses to eliminate chromatic aberrations plus three HR (High-refractive) lenses to maintain a compact physical size and further reduce optical aberrations. ZERO Coating (Zuiko Extra-Low Reflection Optical Coating) on all glass surfaces minimises the effects of flare and ghosting.

The Olympus MSC (Movie & Still Compatible) lens drive system is used to provide very fast and silent autofocusing as well as smooth AF tracking for movie recording. The internal focusing lens elements are driven directly by a metallic shaft and feed screw, which are engineered to submicrometric accuracies.
The new lens can focus to 90 cm at the 150mm setting or 1.5 metres at 300mm. A light weight of 423 grams and a closed length of only 11.65 cm makes this lens easy to carry. The redesigned exterior complements the clean design of the Olympus OM-D camera. With a combined weight of only 848 grams, the OM-D and the M.Zuiko 75-300mm MkII is ideal for travel and field photography.
