Sharpness at 14mm

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Sony FE 14mm F1.8 GM lens was attached to a Sony A7R IV 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 14mm

Centre sharpness is outstanding even when shooting wide-open at f/1.8, through to f/11, with f/16 being adversely affected by diffraction.

The edge performance is almost as good as the centre, with f/2.8-f/11 producing the sharpest results.
