Sony Vario-Tessar T* FE 16-35 mm F4 ZA OSS Review

November 14, 2014 | Mark Goldstein |

Sharpness at 16mm

For this test, the Sony Vario-Tessar T* FE 16-35 mm F4 ZA OSS lens was attached to a Sony A7R 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/16, with f/22 being adversely affected by diffraction. The edges are just as sharp as the centre, with f/4-f/16 producing the sharpest results.
