Sony FE 100mm f/2.8 STF GM OSS Review
Sharpness at 100mm
For this test, the Sony FE 100mm f/2.8 STF GM OSS lens was attached to a Sony A7R II 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 remains high from f/4 to f/16, with f/20 being adversely affected by diffraction. The edges are just as sharp as the centre, with f/4-f/16 again producing the sharpest results.
