Sigma 24-70 HSM opinion
I have had the new Sigma 24-7o f2.8 HSM lens for about 3 weeks now, took photos with it the last four weekends. I am happy with the performance of this lens. This lens controls flare very well( but have had a couple of photos shot directly into the sun show small flare). This lens has good contrast and no color shift. I have had no focus issues with this lens on my Nikon D700 (I did use AF Tune to adjust focus at 70mm -10). Once I adjusted the focus setting, focus point was tack sharp at f2.8. This lens is very sharp even in the corners. The one knock I will give it, is that it Vignettes a little at 70mm with f2.8-4.0 (can be removed in post process). Over f5.6 and up no vignette. I am no professional lense reviewer but I feel this is a good value for the money. I'm sure the Nikon 24-70 is a better lens and for the extra money it should be. For my uses I am very satisfied with the lens. If you want to see some photos taken with the Sigma 24-70 lens type bc1963 photos in...

Exactly what I expected for the $$$ (and a little more)
I'm currently using a Nikon D90 but the D700 is on the horizon for me. This meant that I am not buying any DX lenses anymore. I have the Tokina 11-16, Nikkor 70-300 VR, Nikkor 50mm 1.8 and the D90 kit lens 18-105 VR (never been happy with the kit lens). So the only focal range I needed was basically 17-70 and the DX Nikkor 17-55 is out. The logical approach was the Nikkor 24-70 f/2.8 but ugh... I'm not making $$$ 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...

Great alternative to slow VR zooms
My objective was to find something fast in a normal zoom range. This lens fits the bill. Build quality is excellent with perfect resistance in zoom and focus rings. A bit more expensive than a Nikon 16-85VR, it cost a lot less than a Nikon 17-55, and much, much less than a Nikon 24-70 f2.8. This Sigma f2.8 HSM is probably the only competition for the big Nikon in FX lenses. After cashback I paid about $750. For me the lens handles exceptionally well. I like the large barrel diameter and the short length. I also like the balance on my D300. As others have said, mine had a slight front focus problem at 70mm, close up. I sent it in for adjustment because in all other respects I really like it. Like another review reports, mine came back exactly as it was when I sent it. However, I decided to work with it because it has amazing potential. I started by manually touching up focus for closeups, and you can do that with this HSM lens. Results are fantastic when focus is correct...
