Sigma 14-24mm F2.8 DG DN Art Review
Sharpness at 14mm
For this test, the Sigma 14-24mm F2.8 DG DN Art lens was attached to a Sony A7R IV 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/2.8 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/4 to f/11 producing the sharpest results.
