The Sony FE 16-35mm f/2.8 GM MKII is a professional-grade wide-angle zoom lens designed for Sony full-frame E-mount mirrorless cameras. Featuring an ultra-wide 16-35mm focal length with a constant f/2.8 aperture, this lens excels at landscape, architectural, and video work. The Mark II iteration brings a refined optical design with five aspherical elements (including three XA extreme aspherical elements) and ED glass for exceptional sharpness and contrast across the entire zoom range. Weighing just 547g and measuring 111.5mm in length, it delivers a 20 percent weight reduction compared to its predecessor whilst maintaining the same 82mm filter thread. Four XD linear autofocus motors enable fast, quiet, and precise focusing. The lens features a dust- and moisture-resistant design with fluorine coating on the front element to repel fingerprints and contaminants, plus advanced Nano AR II coatings to minimise flare and ghosting. An eleven-blade aperture diaphragm produces beautiful bokeh, with a 0.22m close focus distance and 0.32x maximum magnification.
