When my wife dropped and broke my Nikkor 18-200Vr lens two days before Hawaiian vacation, I needed a quick replacement. I am so glad I got Sigma 17-70. It stayed on my D300 90% of the time. I love this lens. It is very sharp, as sharp as my Nikkor 18-135 and probably sharper. The 2.8 at wide end is great. The range is respectable for most application and as a walk around. HSM works great and the lens focuses quickly in low light, unlike my Nikon 18-200VR lens (which is twice as expensive). The built is excellent. I took off one star on features because of lack of OS, which would be nice. Overall, I highly recommend this lens, and I specifically recommend it above Tamron 17-50 2.8, which costs $100 more than Sigma, but focuses much slower in low light, despite constant F2.8.
One thing though, at wide end, you have barrel distortion, and it is pronounced and i mean pronounced, to the point, that the Ocean on a background may look like a portion of a large circle. Even PT Lens program struggles with fixing the distortion. However, I personally don't care about barrel distortion, as much as I care about sharpness. I can't stand soft photos! But I just wanted to point that distortion is there.

For the price, the lens works great. I use it for portraits and it comes in very sharp. Definitely will buy Sigma again.

Pictures were sharp and bokeh was decent but my shots lacked contrast and saturation. They just looked a little washed out. At first, I thought I just had exposure setting issues or that my D90 photos simply had a different look to it. I changed my D40 to a D90 about the same time so this wasn't a controlled experiment at the beginning. Later I got some Sigma EX lenses as well as the new 18-250 OS lens that isn't EX and my pics suddenly jumped to life. Richer color saturation and less washed out. I could only conclude that this lens wasn't as good as my new Sigmas. However, I note that the 18-250 lens also has a washed out look when shooting at the very long end.

It is hard to purchase lens online without "test driving" them. When I received it and took it with me on a trip, it was incredible. It has a nice wide angle, and takes very clean pictures. You have to work out the out-of-focused pictures that one occasionally gets when shots are taken from a distance, but I think mostly that is due to the fact this lens is meant for up-close shots.
Over all ... awesome LENS!!!

I have been shooting with this lens for a couple of weeks now and I am impressed with the capabilities. The near-macro capabilities are amazing and I have taken some really nice flower close-up shots. I am very satisfied with my purchase.
