Carl Zeiss Vario-Tessar T E 16-70mm f/4 ZA OSS Review

March 21, 2014 | Mark Goldstein | |

Sharpness at 16mm

For this test, the Carl Zeiss Vario-Tessar T E 16-70mm f/4 ZA OSS lens was attached to a Sony NEX-7 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 remains high through from f/4 to f/11, with f/16 and f/22 being adversely affected by diffraction. The edges aren't quite as sharp as the centre, with f/5.6 to f/11 producing the sharpest results.
