The Sony Vario-Tessar T* E 16-70mm f/4 ZA OSS Lens is a mid-range zoom lens that provides a 35mm-equivalent focal length range of 24-105mm, covering wide-angle to short telephoto perspectives. A constant f/4 maximum aperture offers consistent performance throughout the zoom range and is especially beneficial when working with greater zoom magnifications in low-light conditions. Also benefitting working in dim light or at the long end of the zoom range is Optical SteadyShot image stabilization, which serves to minimize the appearance of camera shake by up to four shutter speed steps.
The optical construction incorporates four aspherical elements to help reduce chromatic aberrations throughout the zoom range as well as contribute to a compact overall form-factor. A Carl Zeiss T* anti-reflective coating has been applied to the lens elements to minimize lens flare and ghosting while providing enhanced contrast, clarity, and color fidelity.
