(More customer reviews)I'm currently using a Nikon D90 but the D700 is on the horizon for me. This meant that I am not buying any DX lenses anymore. I have the Tokina 11-16, Nikkor 70-300 VR, Nikkor 50mm 1.8 and the D90 kit lens 18-105 VR (never been happy with the kit lens). So the only focal range I needed was basically 17-70 and the DX Nikkor 17-55 is out. The logical approach was the Nikkor 24-70 f/2.8 but ugh... I'm not making $$$ from my shots yet and $1999 was a bit much to swallow. I rented the Nikkor and the Sigma to compare side by side and I really loved the Sigma's compact but solid presence compared to the relatively big and long Nikkor (chalk up one point for the Sigma)... I took about 150 shots with both lenses and I really could not find too many differences... Certainly none that stood out. I'll admit that I'm a bit of a pixel peeper and I was truly looking for the lesser priced lens to come up short but honestly only some very minor flare issues (shooting directly into the late evening sun) even showed up. On my crop framed D90 the sharpness was superb on both lenses, color, contrast and focusing accuracy and speed was exactly what I expected. VERY VERY good. One thing that added to the cost of the Sigma though (chalk up a point for Nikkor) is the 82mm filter size. They are not easy to find and are almost always more expensive (high quality Digital UV filter was $100). I now have my FX frame lens lineup set and I'm very happy with it as I purchased this lens right here at Amazon. Now... to save for that D700... *sigh*
Moral of the story is... if you want to save $800 and have a lens that you'd be hard pressed to tell the difference from the venerable Nikkor... get this Sigma 24-70 2.8 HSM.
