A high-performance all-arounder, the Sony FE 28-70mm f/2 GM is a faster standard zoom compared to conventional f/2.8 options. This lens is Sony's first GM zoom with a constant f/2 maximum aperture and spans a useful wide-angle to portrait-length range—it is a lens for photographers looking to replace a set of primes with a single zoom without sacrificing on speed. It covers some of the most frequently used focal lengths, offers impressively fast AF, and is a single, well-balanced option for photography and filmmaking needs. Sony's G Master designation is reserved for its highest performing optics, those that offer the greatest sharpness, smoothest bokeh, utmost speed, and best overall performance. This 28-70mm f/2 checks all of these boxes as it sets out to be a single lens replacement for several primes. Constant f/2 maximum aperture is a full stop faster than an f/2.8 lens, helping this zoom to further excel in low-light conditions and offering even greater control over depth of field and subject-background separation. XA, Super ED, aspherical, and ED elements yield high sharpness and smooth rendering that suits subjects ranging from architecture and landscape to portraiture and weddings. Nano AR Coating II suppress flare for rich contrast and bright colors in a variety of lighting conditions. Floating focus design maintains high image quality throughout the focusing range, resulting in matched sharpness from infinity to the 1.2' minimum focusing distance. Rounded 11-blade diaphragm results in smooth, circular bokeh quality.
