Sharpness at 50mm

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Leica VARIO-ELMARIT-SL 24-70mm f/2.8 ASPH. lens was attached to a Leica SL2-S 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 50mm

Centre sharpness is outstanding through from f/2.8 to f/16, with f/22 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.
