Nice lens which is sharp and is useful for DX format cameras. I would recommend this lens as a 3rd party option to your camera.

Released earlier this year, the Sigma 10-20mm f/3.5 EX DC HSM is a mouthful to say but a true pleasure to work with.  I begrudgingly write this review because it means I have to send the test lens back to Sigma…. …and I really don't want to!

I also bought the Nikon AF-P DX NIKKOR 10-20mm f/4.5-5.6G VR to compare, which runs roughly $100 cheaper. These are both ultra wides. For the money, I found the Sigma superior in quality w/ metal connectors, sturdy body, quality glass and less plastic overall.

This lens is more than I ever expected. The focal lengths are perfect for property photos and a fast lens correction in Lightroom puts everything into place. I love the fixed 3.5 and the 10mm. I have no problems with the SB800 flash providing enough light and coverage.

Consistent Output; Fast / accurate auto-focus; Lightweight

I'veused this lens for over a year, and have loved it. I have made the transition to full frame now so this lens will stay with my crop body as backup and will be sorely missed

Great for croped bodies; amazing range at widest setting; reasonably fast FIXED aperturehandles distorion well; while allowing distorion effects when you want them

Flares can happen with this lens; filter size is large; and expensive at 82mm but a must for landscapes.

"I love this lens! I recently purchased and used it with my Nikon D5100, and I was awestruck by the results. I'm going to now begin with the comment(s) most people look for: ****** CONS ******.

nice build quality . quite less distortion . but the gocus ring is little hard to turn .

Sigma's original 10-20mm f/4-5.6 ticked pretty much all the right boxes, and rapidly became a top seller for users of Canon, Nikon, Olympus, Pentax, Sigma and Sony bodies alike.

A wide-angle zoom is definitely the way to go when photographing in this type of situation, whether it's a car show, antique show, or anywhere that's crowded or the subject is large, such as architecture.

Quality; true cost of lens; construction

Distortion at widest angles

xcellent. Wide Angle,Very sharp and fast and for low lite.

These Sigma 10-20mm F3.5 is my first Lens from Sigma; Absolutely very sharp in my 7d camera it gives me an outstanding color and a wide angle in a tight space.

They should make it zoom
