Tamron 150-500mm F5-6.7 Di III VC VXD Review
Sharpness at 150mm
Our sharpness tests are carried out by photographing a real-world subject rather than a test chart. The Tamron 150-500mm F5-6.7 Di III VC VXD was attached to a Sony Alpha A7 III camera, which in turn was mounted on a sturdy tripod. Self-timer mode was activated to steady the camera completely. Any slight tonal changes you may see across the crops are a result of slight changes in natural light during the shooting session.
The full frame at 150mm
At both the the centre and the edges of the image, sharpness is very good even at the maximum aperture.
It maintains that level of sharpness until f/22, where it remains excellent but is ever-so-slightly softer due to diffraction.
