Tamron SP 45mm f/1.8 Di VC USD Review
September 16, 2015 | Mark Goldstein |
Sharpness at 45mm
The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Tamron SP 45mm f/1.8 Di VC USD 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.
The full frame at 45mm
Both center and edge sharpness are outstanding between f/2.8 and f/8. At f/11 and f/16 sharpness is beginning to drop off to diffraction.
