The M.Zuiko Digital ED 150-400mm f/4.5 TCI.25X IS PRO lens from Olympus is an impressive super telephoto zoom lens designed for use with Micro Four Thirds mirrorless cameras, featuring a range and reach of a 300-800mm equivalent focal length range. Via the integrated 1.25x teleconverter, this focal range can be further expanded to an effective 1000mm equivalent focal length. The constant f/4.5 maximum aperture of the lens, which is slightly reduced to f/5.6 when the teleconverter is in use, affords consistent illumination throughout the zoom range. Optically advanced, the lens incorporates one EDA (extra-low dispersion aspherical) element, four Super ED (extra-low dispersion) elements, two ED elements, two HR (high-refractive index). and one HD element; The combination of these elements affords marked sharpness, clarity, and accurate rendering by minimising various aberrations, distortion and colour fringing. For improving contrast, a Z Coating Nano has been applied to markedly reduce lens flare and ghosting. A circular nine-blade diaphragm produces a pleasing out of focus bokeh quality. An apt optical image stabilisation (IS) system compliments the optics by compensating for camera shake for sharper handheld shooting and shooting in difficult conditions. Additionally, 5-axis Sync IS is supported to reap the benefits of camera-based sensor-shift IS for even more robust stabilisation. 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. Equipped with a fixed rotating tripod collar that improves balance and support when working from a tripod, the lenss magnesium and carbon fiber construction means this telephoto zoom also suitably light enough for handheld use. It also features a weather-sealed construction against dust, moisture, and freezing temperatures provides peace of mind when working in changeable weather conditions, and has a heat-resistant finish. A fluorine coating on the front elements provides for resistance to smudging and fingerprints as well as easier cleaning. This lens comes supplied with a lens cap, rear lens cap, lens hood, case, and strap.
