Sony FE 70-200mm f/4 G OSS Review
Sharpness at 100mm
For this test, the Sony FE 70-200mm f/4 G 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 through from f/4 to f/16, with f/22 being adversely affected by diffraction. The edges aren't quite as sharp as the centre, with f/5.6-f/11 producing the sharpest results.
