Sony FE 20mm f/1.8 G Review

March 2, 2020 | Mark Goldstein |

Sharpness at 20mm

For this test, the Sony FE 20mm f/1.8 G lens was attached to a Sony A7R III camera body, which in turn was mounted on a sturdy tripod. Exposure delay mode was activated. Tonal and colour variances across the crops are due to changes in natural light during the session.

Centre sharpness is outstanding even when shooting wide-open at f/1.8, through to f/11, with f/16 and f/22 being adversely affected by diffraction. The edges performance is almost as good as the centre, with f/2.8-f/11 producing the sharpest results.
