The Sony FE 24-70mm f/2.8 GM II is not only smaller and lighter than the previous generation, but 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. Bright f/2.8 constant aperture allows users to capture images in dim lighting conditions and with a shallow depth of field. Designed to rival the primes, this zoom's optics have been revamped to provide even greater resolution, clarity, and bokeh quality. 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, and 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. Faster focusing performance, improved close-up shooting, and enhanced control are all benefits of the redesigned focusing system. Faster AF means improved focusing when working with fast-moving subjects; support is available for shooting at up to 30 fps, full AF is maintained even when the shooting stopped down, and focus tracking is possible even when changing the zoom position. The floating focusing mechanism helps maintain image quality throughout the focusing range, which is especially important considering the impressive close-up performance of this lens: a minimum focusing distance of 8.3" at the 24mm position or 11.8" at the 70mm position and a maximum magnification of 0.32x at the 70mm position. The XD Linear Motors are also especially quiet to better enable the use of AF during video recording. Dust and moisture-resistant design includes rubber gaskets at each seam and a rubber ring sealing the lens mount for ensured use when working in inclement weather conditions. The included lens hood features a locking button and a filter window for easier adjustment of rotating filters Two programmable focus hold buttons and a focus mode switch for intuitive focus control. 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.
