Customer Reviews

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 your search engine and select my flickr photostream.


Review Update 4-15-09:

After using the lens more I wanted to update the review with my observations to date. I have had a couple photos with lens flare but it was small and shot directly into the sun. Also I have seen some vignette at f4.0.

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 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.

Great Lens
Recently jumped into the FX ... full frame world and bought a nikon d700, I really did want to spend $1900 on a nikkon 24-70mm so i made my homework and pretty much found out the only real challenger for the nikkor is the sigma 24-70mm.
Bought the lens, have been using it now for over 2 weeks, very sharp, im getting awesome picture, great contrast, no vignetting at least on 24-60mm range.
I simply love the lens.
Some people dont like that fact that the lens is an 82mm one, on the other hand i love it, somehow the size helps me get more stable results while grabbing the camera.
Highly recommend this lens
