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.
