The M.Zuiko Digital ED 100-400mm f/5-6.3 IS lens from Olympus
is a super telephoto zoom lens designed for use with Micro Four Thirds
mirrorless cameras, featuring an impressive range and reach of a 200-800mm equivalent focal length range.
Optically advanced, the lens incorporates two Super HR (high-refractive index) and two HR elements for improved sharpness by minimising spherical aberrations. A further three ED (extra-low dispersion) elements control chromatic aberrations and colour fringing for greater clarity and colour fidelity. For improving contrast, a ZERO coating has been applied to markedly reduce lens flare and ghosting. A circular nine-blade diaphragm produces a pleasing out of focus 'bokeh' quality.
An optical image stabilisation (IS) system compliments the optics
by compensating for up to three stops of camera shake for sharper
handheld shooting and shooting in difficult conditions. A Movie & Stills Compatible (MSC) autofocus system
provides quick, accurate, and quiet focusing performance, benefitting
both stills and video applications. An incorporation of a focus limiter switch
provides three focal ranges to further quicken focusing, depending on
the anticipated subject-to-camera range. It is also equipped with a removable rotating tripod collar that improves balance and support, and a weather-sealed construction against dust, moisture, and freezing temperatures provides peace of mind when working in changeable weather conditions.
