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.
