Product ReviewsSigma DC 10-20mm f/4.0-5.6 HSM EX IF ASP DC Lens For Canon

Always test a lens when you get one.

The Sigma 10-20mm is a great lens for the money.

However, I suggest that if you buy one you test it first!

It wasn't until I brought some images on to my computer that I noticed that my copy of the lens is soft.

I made sure it wasn't an error on my part by doing a simple test: Use a tripod, a remote shutter, and mirror lockup, and shoot at different focal lengths and apertures.

The "sweet spot" for this lens if f/8-11, and even messing about with different shutter speeds, my images are soft, as in, soft ALL OVER the image. Something you WILL find with nearly every copy of this lens is that it is a bit soft on corners, which is to be expected; it is a very wide focal length.

Luckily it comes with Sigma's warranty, so I will be able to send it to them and have them fix it for free. I will change my rating if I find that the fix makes it better.Read full review...

LOVE IT!! Awesome Lens package

Was looking at the Canon 10-18 mm . This is better. You get more for your money. Clear and crisp glass. I love the fact it comes standard with the case and lens hood. It was heavier than I expected for a small lens but that means it well built. Can't wait to take it out on my road trips across the country. Great price and lens Read full review...

Lightweight and Great for the Price

I purchased this lens to use for landscape photography. The seller was excellent and helped the transaction go very smoothly.

Excellent ulta-wide/wide angle lens. I have combined it with a 77mm polarizer for my outdoor photos and have been extremely happy with it.Read full review...

Cheaper/ Wider than Canon/other competition. Get one and have fun!

I bought this lens to cover the wide angle focal lengths for my photography. I couldn't afford the expensive canon 10-22mm but opted for this against Tokina 11-16/ 12-24 and Tamron 10-24.

I'm very glad I settled for this and got a great copy. Sure it's a bit slower than the other brands but for a wide angle lens, you are most likely have to stop down. The Built quality is awesome, I loved the HSM motor, very fast and silent. I haven't had a chance to compare this lens to other competitions but I'm pretty sure I'll still settle for the widest focal which is 10mm.

Some people hate the distortion of this kind of lens but I love it! especially for portraits, it makes it fun and artistic. Lens flare has not been a real issue for me because that's easy to handle.

Overall, this lens has been on my 60d since I bought it, and if you need a wide angle that's affordable and has a lot of great feedbacks, then definitely get this lens.

The new version of this lens has a constant F/3.5 which may be helpful to some but for a personal experience I think there's not much difference. If it would've been F/2.8 now that's a different story. So I say save your money from the much expensive F3.5 version.

So yeah, I recommend this rad lens to anybody looking to go wide. You Will L O V E it!

Cheers, go out there, keep shooting and be safe.

Great wide lens for amateur landscape photography

I got this lens because I wanted something wide for a trip I'm taking to several of the national parks this summer. I've brought it on a few hiking trips so far to test it out, and I am thoroughly pleased with the results! I'm a complete amateur photographer, and this lens has totally fit my needs. The images are plenty sharp for me, and the price tag on this lens really can't be beat. No, it's probably not fit for a professional, but if you're just looking for a wide lens to capture great landscape scenes, this is the lens for you!Read full review...

A lot better than I expected!

I searched everywhere looking for an inexpensive but decent wide angle lens for my canon dslr. I wasn't expecting to like this lens near as much as I do. It is perfect for the tight shots where I need to show a lot of the room or area but at the same time isn't too superwide like an action camera.

It's also heavy duty. Well Built.

Makes a great and affordable addition to your lens collection.Read full review...

Amazing lens

I love the lens. It does its job well! The only reason I gave it a 4 star is because it didn't come when it said it would be here. But the company did give me some filters for the trouble. Wasn't happy about it being late but was happy with how the company treated me.Read full review...

Signs 10-20mm extreme wide angle.

I'm in love with this lens. I do a lot of scenery and landscapes including very large buildings.
Sharpness is there, extreme wide capture and quick to focus lens. I bought this lens to travel with and I find I'm using this as my go to lens.Read full review...

Well worth the price

I purchased this lens because I couldn't take some pictures that I could see in my mind, because I couldn't get quite far enough away to fit the entire picture in my viewfinder with my 18mm-55mm lens.

My first alternative was to add a 0.42 adapter to the front of my 18mm-55mm lens- an adptor that would essentially double the area coveredby the picture. That basically worked for objects in the middle of the picture, but the far edges were out of focus ... and if my interest were in the center only, then I wouldn't have been going through this exercise!

Using this lens, my picture covers roughly the same area as the 18mm-55mm + adapter did, but the picture is uniformly in focus.Read full review...
