Tokina Opera 50mm F1.4 FF Review
Sharpness at 50mm
For this test, the Tokina Opera 50mm F1.4 FF lens was attached to a Canon EOS 5DS R 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/2 to f/11, with f/16 being adversely affected by diffraction. The edges aren't quite as sharp as the centre, with f/4-f/11 producing the sharpest results.
