The Sony FE 28-70mm f/3.5-5.6 OSS Lens is a versatile, compact, and lightweight wide-angle to portrait-length zoom lens designed specifically for full-frame E-mount cameras. It is also compatible with APS-C-sized image sensors and will provide a 35mm-equivalent focal length range of 42-105mm. In regard to the optical design, three aspherical elements and one extra-low dispersion element help to reduce aberrations and distortions while contributing to notable image sharpness and clarity. This lens also integrates Optical SteadyShot image stabilization to lessen the appearance of camera shake when working in low-light conditions or with longer focal lengths. Additionally, a dust- and moisture-resistant construction ensures this lens' use in tough environmental conditions.
