The Sony Vario-Tessar T* FE 24-70mm f/4 ZA OSS Lens is a wide-angle to portrait-length zoom lens that features a constant f/4 maximum aperture to support consistent performance in regard to exposure settings and focus placement throughout the zoom range. Five aspherical elements and one extra-low dispersion element help to reduce aberrations and distortions while contributing to notable image sharpness and clarity. A Carl Zeiss T* anti-reflective coating has also been applied to lens elements to reduce lens flare and ghosting for improved contrast and color fidelity.

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.
