I am looking for a wide angle lens for my EOS 40D. I have narrowed my search down to the Canon 10-22 EFS and the Sigma 10-20. Which one is the better lens ? Is the Canon worth the extra cost ? Any help in deciding would be appreciated.
 
I have the Sigma. Having seen so many examples of fine picures on this forum from owners of such I thought why spend more on the Canon. At my level I am very happy with the Sigma/cost so it's something to take into account. If you get the Sigma and aren't happy then you can sell it (without loss) and go for a Canon.
 
I have the Canon use it above and underwater - excellent quality for the cash I would say...have not used Sig so could not comment. Always pays to buy the the best...check out www.the-digital-picture.com/ for detailed Canon review. HTH:thumbs:
 
Another vote for the Canon! :thumbs:
 
I love my Canon 10-22mm too, without doubt the results have made me smile more than any other lens I own, but as for the price difference, I doubt you could ever justify it.

If it's going to be with you a long time what will you feel happiest with?

I was just lucky/daft enough to be able to afford one while their cashback offer was on! This was the 24th picture taken with my 40D since I bought it and my 10-22mm lens but don't let it put you off.

I have the Sigma 10-20, build quality is good. If you get a good copy, its a brilliant lens. I've read good reports on the Canon 10-22, maybe its better if you get one.
 
Vote for sigma here, tremendous lens, can't fault it.
 
I think the results speak for themselves, they are both good lenses. There are loads of threads on the internet comparing the two, take your camera to a shop that stocks both and see if you can play with them.

Another option is the Tokina 12-24mm

They are all good lenses, so no doubt you will be pleased with whatever you purchase. So the question really is whether the canon is worth the extra?


I have the Sigma and think it is a great lens, but can't vote for it over the others as I have never tried them.
 
From reading this thread over and over again over the months, I've come to the completely non-tested conclusion that the Sigma is perfectly adequate, but the Canon is better.
 
17mm on full frame is nearly just as wide as 10mm on a cropped sensor
 
10mm on a 1.6x crop is technically a 16mm lens. If you put the 10mm on a FF body its 10mm but you can see the lens so it doesn't work.

Narrowed the search means you've already eliminated the Tokina 12-24? I like this lens as it is constant f/4.

Between the Canon and the Sigma. Another difference is that the Canon has f/3.5-4.5 while the Sigma has f/4-5.6. So the Canon has a slight advantage in max aperture. While the Sigma has the ability to be mounted on a FF camera (but probably has super heavy vignetting at wider angles).

So, what would my 12 - 24 Sigma be on a full frame......?

I've used the Sigma 12-24 on full frame, and the view you get at 12mm is amazing!
However, when I put my Tokina 12-24 on full frame, I see black corners until about 19mm.

Unlike the Canon 10-22, the Sigma 10-20 should be able to be mounted on a FF camera, but you would probably experience black corners at the wider angle. Just realised I already mentioned this above :D
 
I have the Sigma 10-20 and its my favorite lens, however if I'd had the money, I would have got the Canon...Just a personal thing though

Also, the Sigma 10-20 cant be used on a ff camera as it is a "DC" designation lens, but the Sigma 12-24 can.
