Tamron SP 24-70mm F/2.8 Di VC USD Sharpness Cont... 3

Sharpness at 50mm

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 lens was attached to a Canon 5D Mark 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.

Center sharpness is outstanding between f/4 and f/8, with some softness evident wide open at f/2.8. At f/11 to f/22 sharpness is beginning to drop off significantly. Edge sharpness is best at f/8.
