Samyang AF 14mm f/2.8 FE Review
Sharpness at 14mm
For this test, the Samyang AF 14mm f/2.8 FE 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 is acceptable when shooting wide-open at f/2.8, and very good from f/4 onwards, with f/22 being adversely affected by diffraction. The edges aren't nearly as sharp as the centre, with f/8-f/16 producing the sharpest results.
