Sony SEL70200GM2 QSYX FE 70-200 mm F2.8 GM OSS Zoom Lens

Sony announced the Sony FE 70-200mm F2.8 GM OSS on February 3, 2016, as a premium, constant maximum aperture full-frame (FE) telephoto zoom lens for the Sony E-mount. The 70-200mm f/2.8 lens is popular among event photographers and photojournalists who need to shoot in low light. The improved background blur produced by the f/2.8 aperture is also preferred by some portrait photographers. Though designed for Sony's full-frame E-mount cameras, the lens can also be used on Sony's APS-C E-mount camera bodies, providing an equivalent full-frame field of view of 105-300mm. The lens is made of weather-resistant plastic and metal and has a rubber focus and zoom ring. External controls are provided for enabling image stabilization, limiting the focal range of the lens, and changing focusing modes. It also has three external focus-hold buttons for locking in focus on a moving subject. Throughout its zoom range, the lens maintains its physical length. The Sony FE 70-200mm F2.8 GM OSS lens is one of the few telephoto lenses available from Sony that is compatible with their dedicated 1.4x and 2.0x lens teleconverters. When used together, the combination produces an effective focal length of 98-280mm (f/4.0) and 140-400mm (f/5.6). At its maximum aperture of f/2.8, the lens is exceptionally sharp throughout its zoom range. Control over distortion, vignetting, and chromatic aberration is excellent. When using the 1.4x and 2.0x teleconverters, image quality suffers slightly but remains reasonably sharp.
