Sharpness at 70mm
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.
The full frame at 70mm
Centre sharpness remains high through from f/5.6 to f/11, with f/16 and f/22 being adversely affected by diffraction. The edges are almost as sharp as the centre, with f/5.6 to f/11 again producing the sharpest results.
