Sony Vario-Tessar T FE 24-70 mm f4 ZA OSS Lente Nergo

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.
