Sigma 24-35mm f/2 DG HSM Art Review

August 26, 2015 | Mark Goldstein |

Sharpness at 24mm

For this test, the Sigma 24-35mm f/2 DG HSM Art lens was attached to a Canon EOS 5DS R 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/8, with f/11 and f/16 being adversely affected by diffraction. The edges are as sharp as the centre, with f/2.8-f/8 again producing the sharpest results.
