Sharpness

Sharpness at 16mm

For this test, the Sony DT 16-50mm F2.8 SSM lens was attached to a Sony A77 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 16mm

Centre sharpness remains high through from f4 to f/11, with f/16 and f/22 being adversely affected by diffraction. The edges aren't nearly as sharp as the centre, with f5.6-11 producing the sharpest results.
