Tamron 28-75mm f/2.8 Di III RXD G2 - £828/$999

The polar opposite of a 'dumb' lens

- Matthew Richards

1 The zoom and focus control rings have more of a tactile feel to them.

2 The focus button can be assigned top operating functions like the focus preset.

3 Overall, the build and quality of the lens is very good, especially at the asking price.
