Tamron SP 24-70mm F/2.8 Di VC USD G2 Review

September 22, 2017 | Mark Goldstein | |

Sharpness at 70mm

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Tamron SP 24-70mm F/2.8 Di VC USD G2 lens was attached to a Canon 5DS R 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.

Both center and edge sharpness are outstanding between f/4 and f/11, with some softness evident wide open at f/2.8. At f/16 and f/22 sharpness is beginning to drop off a little due to diffraction.
