Sigma 85mm F1.4 DG HSM Art Review

Sharpness at 85mm

For this test, the Sigma 85mm F1.4 DG HSM 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 is outstanding from f/2 to f/11, with f/16 being adversely affected by diffraction. The edges are commendably just as sharp as the centre, with f/2 to f/11 again producing the sharpest results.
