Great wide angle lens

None

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.

This professional standard lens impressed our tester. Find out why by reading the Sigma 10-20mm f/3.5 EX DC HSM lens review.

Stunning performance

Slight focusing stiffness

This is an excellent lens for the money. At 10mm (F3.5( it was slightly soft but after 11mm the images were very sharp (F.4 and up). The quality and feel of this lens is really nice. It is a nice fit and nice price for my 7D.

Light lens compared to my 16-35mm; nice color and decent low light performance; nice build quality

Little soft at 10mm but sharpens quickly above 11mm

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

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

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

Following in the footsteps of Sigma's full-frame 12-24mm DG zoom, the 10-20mm DC version has a lot to live up to. Fortunately, it is not only equal to the challenge but also pulls ahead in several important respects.

Good all-round performance

Nothing really

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.
