Sigma EX 10-20mm F/4.0-5.6 AF HSM DC Lens For Canon

An excellent buy. I wanted a wide angle lens for some time but did not want to spend a whole lot since I am just a leisure photographer, mostly on vacation. The autofocus is fast and images come our great. Be sure to but the filters for this lens. Since it is so wide you let in a lot of light and may want to get a general UV filter and perhaps a polarizing filter if you like shooting outdoors especially near water. I am sure the Canon is better quality but for the difference in price it is well worth it.

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.

I guese it was my fault. This is a old new lens. It took one picture and had a contact error. I called sigma it for a pre digital camera. it wont work on digital. but it is the lens he advertised. buyer be ware.

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.

I love this lens for my wide angle needs. Sharp pictures and nice color. Quite a bit of vignette when wide open though. This can add or detract from the finished product
