The Sony FE 70-200mm f/2.8 GM OSS Lens easily takes its place as the de facto telephoto zoom for professionals. A member of the G Master series, this 70-200mm delivers high sharpness alongside smooth, clean bokeh with an absolute minimum of aberrations. This is guaranteed through the use of an XA element, two aspherical elements, four extra-low dispersion elements, and two Super ED elements in the optical design.  Bokeh is made even better by the implementation of an eleven-blade circular diaphragm for smooth out-of-focus areas. Also, there is a double-linear and ring Super Sonic wave Motor system that provides fast, responsive autofocus in both stills and video. Users will enjoy faster and more intuitive operation with a plethora of physical controls on the lens barrel, including three focus hold buttons, a focus range limiter switch, and both AF/MF and OSS switches. For durability and working in tough conditions, the lens is dust and moisture-resistant, and it has a fluorine coating on the front element to resist water and oil. A popular telephoto zoom designed for full-frame E-mount mirrorless cameras, this 70-200mm lens is also compatible with APS-C models where it provides a 105-300mm equivalent focal length range. Of the three aspherical elements incorporated in the lens design, one is an XA element with superior surface precision to effectively reduce astigmatism, field curvature, coma, and other monochromatic aberrations from imagery. A Nano AR Coating has been applied to reduce surface reflections, flare, and ghosting for increased contrast and color rendering in strong lighting conditions. This stabilization system can also be combined with a select camera's sensor-shift type image stabilization for more effective control of camera blur. An OSS Mode switch lets you choose Mode 1 for general image stabilization which is suited to most types of shooting as well as a Mode 2 setting that is specifically intended to be used with panning movements. The lens barrel is equipped with three focus hold buttons and a focus range limiter switch to permit fast, intuitive operation of the lens while shooting. A rounded 11-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques. The included petal-shaped lens hood helps prevent flaring and has a filter access window for making adjustments to rotating filters such as polarizers and variable NDs.
