Sigma 16mm, 30mm and 56mm F1.4 DC DN C for Canon Review
Sharpness at 30mm
The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Sigma 30mm F1.4 DC DN C lens was attached to a Canon EOS M6 Mark II camera body, which in turn was mounted on a sturdy tripod. Self-timer mode was activated. Slight tonal changes are due to slight changes in natural light during the session.
The full frame at 30mm
Centre sharpness remains high through from f/2 to f/11, with f/16 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.
