The Portable Standard Zoom
Walk around all day with the Vario-Tessar T* FE 24-70mm f/4 ZA OSS Lens from Sony, a compact full-frame option that covers wide-angle to short telephoto perspectives for working with a variety of different shooting styles and subjects.
 
ZEISS Optical Design
Based on the ZEISS Tessar optical concept, this lens uses a design with 12 elements in ten groups that helps ensure a smaller overall lens size along with reduced flaring, distortion, and chromatic aberrations.
A constant f/4 maximum aperture offers consistent performance throughout the zoom range and also lends greater control over focus position for shallow depth of field techniques.
ZEISS T* anti-reflective coatings have been applied to each lens surface to help minimize reflections in order to provide greater image clarity, contrast, and color fidelity.
