Tamron SP 90mm F/2.8 Di MACRO 1:1 VC USD (Model F017) Review

May 30, 2016 | Mark Goldstein |

Sharpness at 90mm

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Tamron SP 90mm F/2.8 Di MACRO 1:1 VC USD (Model F017) 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 sharpness is outstanding between f/4 and f/11, with slight softness evident wide open at f/2.8. At f/16 sharpness is beginning to drop off a little due to diffraction, with f/22 and f/32 particularly affected.
