Hi guys and girls,
I know most love the tamron 17-50 none vc as its great vaule and IQ is very good.
I have read some reviews and lab data which show the Sigma 17-50 f2.8 OS is sharper across the range, built better and faster to focus than both the Tamron and the Canon 17-55 f2.8 IS.
Has anyone used all 3 lens? Anyone want to share your thoughts? What one of the 3 gives the best IQ?
