Sharpness at 50mm

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Sony FE 50mm F1.2 GM lens was attached to a Sony Alpha 1 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

The centre is satisfyingly sharp even wide open at f/1.2, with the peak performance achieved in the f/2-f/11 range. Diffraction sets in at at f/16.

The edges are a little soft at f/1.2, sharpening up at f/2, with f/2.8-f/11 the optimum settings.
