Carl Zeiss Vario Tessar T* FE 24-70mm F4 ZA OSS Review
Carl Zeiss Vario Tessar T* FE 24-70mm F4 ZA OSS Sharpness at 50mm
For this test, the Carl Zeiss Vario Tessar T* FE 24-70mm F4 ZA OSS lens was attached to a Sony A7 body, which in turn was mounted on a sturdy tripod. Exposure delay mode was activated. Tonal and colour variances across the crops are due to changes in natural light during the session.

Centre sharpness is impressively high through from f/4 to f/16, with f/22 being adversely affected by diffraction. The edges are not quite as sharp as the centre, with f/5.6-16 producing the sharpest results.
