Sigma 85mm F1.4 DG DN Art Review
Sharpness at 85mm
For this test, the Sigma 85mm F1.4 DG DN Art lens was attached to a Sony A7 III body, which was in turn mounted to a sturdy tripod. Exposure delay mode was activated. Tonal and colour variance across the crops are due to change in natural light during the session.
The full frame at 85mm
Centre sharpness is slightly soft wide-open at f/1.4, but outstanding from f/2 all the way through to f/11, with f/16 being adversely affected by diffraction.
The edges are commendably as sharp as the centre, with f/2 to f/11 again producing the sharpest results.
