Sony FE 24-70 mm F2.8 GM II (SEL2470GM2)
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. Five aspherical elements, including two extreme aspherical elements (XA), minimize spherical aberrations, and distortion, and also reduce 'onion ring' bokeh. Four XD (extreme dynamic) Linear Motors contribute to greatly improved focusing performance, compared to the DDSSM system of the predecessor, including faster, quieter, and more precise AF that's ideal for both photos and stills. 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: minimum focusing distance
