Tamron 17-50mm f/2.8 XR Di II VC LD Aspherical IF SP AF

I use this lens on a Nikon D300S. I have previously used the Nikon AF-S 17-55 f/2.8, and the Tamron 17-50 f/2.8 (NON-VC).

The lens is very sharp and works every bit as well as the previous non-VC version, if not better in every aspect. I have no concerns with the sharpness wide open, contrast is excellent.

It has a bit more CA then the Nikon 17-55 and just doesn't have the corner sharpness of the Nikon, but otherwise is a near match.

Its fast to focus and accurate on my D300S. From time to time it will focus incorrectly, but it is not often (maybe 1 out of 50 attempts).

However this lens was a bit less 'rosy' on a D90. Focus is bit slower, especially in low light. The difference between the focus speed of the Tamron and the Nikon are more evident with the D90, than the D300S.

While I am sure many will disagree, this lens has allowed me to part ways with my Nikon. The easily digestible $625 (after rebate) price and 6-year warranty have made this lens my new primary lens.

I wouldn't hesitate to recommend this lens to anyone.
