A popular pick for professionals using full-frame A-mount cameras, the Vario-Sonnar T* 24-70mm f/2.8 ZA SSM II Lens from Sony covers many of the most commonly used focal lengths in its wide-angle to short telephoto range, which make this optic an outstanding option for photographers working quickly in a variety of shooting situations. Offering a constant f/2.8 aperture, shooters will enjoy consistent exposure throughout the zoom range. Also, the lens design incorporates two aspherical elements to combat aberrations and uses the Zeiss T* coating to effectively eliminate flare.
