Sharpness at 35mm

For this test, the Tamron 28-75mm F2.8 Di III VXD G2 lens was attached to a Sony Alpha A7 IV body, which was in turn mounted to a sturdy tripod. Exposure delay mode was activated. Tonal and colour variance across the crops are due to change in natural light during the session.

Center sharpness is outstanding between f/2.8 and f/11. At f/16 and especially f/22 sharpness drops off a little due to diffraction.

Edge sharpness is just as good as in the centre, with the sharpest results between f/2.8 and f/11.
