Customer Reviews

Sigma - another great product at half the cost of Nikon's
Great product. I have used it with my Fuji S5 pro (crop factor 1.5X). At 10mm focal length, I am actually at 15mm (with my camera's crop factor)...quite wide. It's been great for landscape shots. You get a tad bit of vignetting, but they can be fixes with PS or cropped.

Great product...thank you Sigma

Great lens, great price!
I got this lens recently, and I'm impressed. The photos I've taken with it have turned out great. I just added a multicoated UV filter for protection and a multicoated polarizer for stunning landscapes. Now I just need to work on composition and getting to good locations at the right time! Some have said this lens is "plasticky", but it seems solid to me.

Fantastic value and performance...
For what I need this lens is fantastic. The widest zoom I can get for my D40 at a great price. The lens feels very well made and sturdy; the photos are sharp. The only thing I don't like about it is the weird finish but that's no big deal. Highly recommended.
