Sigma 24-70mm F2.8 DG DN Art Review
Sharpness at 24mm
For this test, the Sigma 24-70mm f2.8 DG DN Art lens was attached to a Sony Alpha A7 III 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 outstanding through from f/2.8 to f/16, with f/22 being adversely affected by diffraction.
The edges aren't quite as sharp as the centre, with f/4 to f/11 producing the sharpest results.
