Sharpness at 50mm

For this test, the Sigma 50mm F1.2 DG DN Art lens was attached to a Panasonic Lumix S5II 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.

Centre sharpness is very good wide-open at f/1.2, and outstanding from f/2 through to f/11, with f/16 being adversely affected by diffraction.

The edges are just as sharp as the centre, with f/2 to f/11 again producing the sharpest results.
