Sharpness Cont... 4

Sharpness at 200mm

The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Tamron AF 18-200mm F/3.5-6.3 Di II VC PZD lens was attached to a Canon EOS 60D for this test and mounted on a Manfrotto tripod. The lens was set to manual focus to ensure constant focusing throughout. A short two second self timer was used to reduce vibration as well as the mirror lock up mode. Photographs were taken indoors in ambient light so any changes in colour or exposure are due to that.

The full frame at 200mm

The full telephoto setting of the Tamron lens still retains that relatively close focusing which is great. Our sharpest results came at around f/16.
