Sony FE 20-70mm F4 G Full-Frame Ultra-Wide Standard Zoom Lens for E-Mount with Constant F4 Aperture, Dual XD Linear Motors and Aperture Ring - SEL2070G

The Sony FE 20-70mm F4 G covers an ultra-wide 20mm to short-telephoto 70mm in one compact full-frame zoom, a versatile choice for landscapes, travel, vlogging and portraits. A constant F4 aperture keeps exposure consistent across the zoom range, and the wide 20mm end keeps a generous view even in 16:9 movie formats. Two AA elements, one aspherical, three ED and one ED aspherical element correct chromatic and spherical aberration right to the image edges. Two XD linear motors drive fast, quiet focus that tracks subjects for continuous stills at up to 30fps and smooth movies, with reduced focus breathing. Focus as close as 0.25m for 0.39x close-ups. An aperture ring with click on/off switch, two customisable focus hold buttons and a focus mode switch give direct control, while a dust and moisture resistant design and fluorine front coating suit outdoor work.
