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

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

I have just recently bought this lens and it is fantastic. It is amazingly crisp and works a treat. Highly recommended.

Beach Camera did a GREAT job in getting it to me QUICK!!! Thanks!

Fast / accurate auto-focus; Strong Construction; Durable; Lightweight; Rugged; Consistent Output; Easily Interchangeable

Although I can't compare this to other UWA lenses I can compare it to other zoom lenses I have (such as Sigma 17-70) and this lens beats them hands down. Feel and build quality is excellent. HSM focussing is wonderful. Flare resistance is surprisingly good for a UWA.

Very sharp center; nice feel; good auto focus; very useful range

Corners at 10mm could be sharper

Sharp images across it's range. Quality build. Worth every cent...

This Sigma wide-angle comes in at a very reasonable price for what it is and for its features. It's also available for plenty of lens mounts. This lens is considered by some photographers as the benchmark for APS-C wide-angles, though our tests suggest this may not now be the case.

Great wide angle lens

None

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.
