Tamron 28-75mm F2.8 Di III VXD G2 Review
November 24, 2021 | Mark Goldstein |
Sharpness at 75mm
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.
The full frame at 75mm
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 almost as good as in the centre, with the sharpest results between f/4 and f/11.
