The Sony FE 70-200mm f/2.8 GM OSS photographic lens easily takes its place as the de facto telephoto zoom for professionals. A member of the G Master series, this lens delivers high sharpness alongside smooth, clean bokeh and 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. Furthermore, the lens has a Nano AR Coating that reduces reflections, flare, and ghosting for improved contrast and color. Optimized for speed, this Sony FE 70-200mm f/2.8 GM OSS photographic lens is equipped with a fast and constant f/2.8 aperture that will be an asset in low-light conditions as well as for creating images with shallow depth of field.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. As a top end telephoto zoom, this lens is equipped with a variety of other technologies to assist shooters, including Optical SteadyShot image stabilization for combating camera shake, especially at longer focal lengths. 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 Sony FE 70-200mm f/2.8 GM OSS photographic lens is dust and moisture resistant, and it has a fluorine coating on the front element to resist water and oil.
