Tamron 35mm F/2.8 Di III OSD M1:2 Review
Sharpness at 35mm
The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Tamron 35mm F/2.8 Di III OSD M1:2 lens was attached to a Sony Alpha A7 III body, which in turn was mounted on a sturdy tripod. Self-timer mode was activated. Slight tonal changes are due to slight changes in natural light during the session.
The full frame at 35mm
Center sharpness is excellent wide-open at f/2.8 and outstanding between f/4 and f/11. At f/16 sharpness is beginning to drop off slightly to diffraction.
Edge sharpness is not quite so good as at the centre, with peak performance between f/5.6-f/11.
