Overview - A refined take on the fast standard zoom, the Sony FE 24-70mm f/2.8 GM II is not only smaller and lighter than the previous generation, it also features a variety of optical, focusing, and handling upgrades, catering to both photo and video applications, that make this the most well-rounded G Master zoom to date. - Designed to rival the primes, this zoom's optics have been revamped to provide even greater resolution, clarity, and bokeh quality. - Bright f/2.8 constant aperture allows users to capture images in dim lighting conditions and with a shallow depth of field. - Two ED (extra-low dispersion) and two Super ED elements effectively suppress chromatic aberrations and color fringing for greater clarity and color fidelity. - Five aspherical elements, including two extreme aspherical elements (XA), minimize spherical aberrations, distortion, and also reduce 'onion ring' bokeh. - Nano AR Coating II controls flare and ghosting with support from a new optical design that reduces internal reflections. - An 11-blade aperture diaphragm helps create smooth, circular bokeh at all aperture settings.
