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.

My first experience with a wide angle lens! Whilst this lens in comparison to a standard zoom affords additional coverage, there are unfortunately, a couple of negatives. At its widest angle there is noticeable fringing / chromatic aberration towards the edges of the image which in most cases can be...

Easy to use; Build quality

Bulky

Love the effects with short depth of field. Nice lens for landscapes. Not experienced enough photographer to quote on lens creep or vignetting but for an amateur like me, a lovely wide lens for my entry Nikon D3100, producing very good pics.

Consistent Output; Easily Interchangeable; Lightweight; Quick Focus; Strong Construction

This is a great quality performing lens. I have had the Sigma 10-20mm 3.5 for 5 years and I cannot fault it.

The lens produces quality results, and the build quality is strong. Would recommend for landscape photography, or even capturing Dubai's skyline.

Build quality; Sharpness; Focal length range

Edge distortion

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

Great wide angle lens

None

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.

f3.5 aperture throughout the entire zoom range and is perfect for low light photography. Sigma wide angle lenses accentuate the relationship of subjects within a photo and thus become an important creative tool.

Got this lens for a fairly good deal compared to the going rate, was delivered quickly and safely. For landscape photography its one of the best lens for the money. Of course its great to spread the cost with an account.
