I have it as well. It's a good allround lens, build like a tank, but with a rather slow AF (not that bad tough), strong vignetting (on a D60 with a 1.6x cropfactor) and soft.

As simple as that: you get, what you pay for. It's not an L lens, but unfortunately, in that range, there's not much variety.

I would look instead at the Tamron, it's getting wicked reviews...

Tamron buys good reviews, they don't earn them...

Lol...and you know this how? They are no different then any other manufacturer looking for reviews.

I have seen different comparisons made with Tamron and Sigma. The Sigma was far better, mainly regarding sharpness.

If only I could find a link .....

I didn't say they are the only ones guilty of the practice  Smile
Just never base your opinions on magazine reviews (or website reviews) exclusively, that's all I wanted to say, as they're often biassed.

Prime example: one "review" came to the conclusion that the 28-200 Tamron (an early model at that) was superior in all respects to the combo 28-80 f/2.8 AF-S Nikkor/80-200 f/2.8 AF-S Nikkor.

The "review" never mentioned optics at all, giving as "reasons" for the conclusion:
- the Tamron weighs less
- the Tamron costs less
- you never have to change lenses

Some test pics are here. The original text is in Japanese or so. The link is to an bablefish translation. So, don't even try to understand  Wink Just find the pics and compare them.

Thanks for the info guys. And lovely shot Kaz. Seems the Sigma is sharper, but a bit more prone to vignetting at short focal lengths (a problem with both lenses). I've also come across a review by someone who says he tested three copies of the Sigma and they all front-focussed at or near full zoom. He suggested that this was because of an incompatibility with the Canon autofocus mechanism. Kaz have you had any such problems?
