Small Size, Huge Versatility 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. G Master Image Quality 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. Improved Control and Video Capabilities Just as camera design has grown to appeal to both photo and video shooters, this lens has also been updated with a series and attributes that specifically appeal to video shooters' needs. Focus breathing, focus shift, and axial shift during zooming have all been minimized to prevent unwanted movements and angle of view variations for greater compositional accuracy during recording. Compact, Lightweight, and Robust Design Among the smallest and lightest f/2.8 standard zooms available, this lens doesn't lose sight of its professional attributes and also remains a weather-sealed, durable lens for use in trying working conditions. Approximately 22% lighter and 18% smaller than its predecessor, this zoom is a highly portable and versatile option for a huge variety of shooting applications. Now fit with a manual aperture ring, tactile exposure control is possible. This ring can be de-clicked for smooth and silent iris pulls or it can be locked in the 'A' position for camera-based aperture switching. Two programmable focus hold buttons and a focus mode switch for intuitive focus control. Zoom smoothness switch for changing between Smooth and Tight zoom ring torque.
