Is it the best lens??

What camera body do you have and what lenses do you own already? There is no such thing as a 'best lens', but the lens might be best for your needs.

For future reference, please just type it, not everybody wants to be linked out to some commercial website.
For what it's worth, the Canon EF-S 10-22mm f/3.5-4.5 USM is a very decent wide angle lens for 1.6 crop cameras. Some might say it's the best option for ultra wide angle.

I wouldn't use it for weddings though, but imo, if you need to ask which lens to use for a wedding, you have no business shooting weddings at a professional level...

Hello, all guys, what do you think about this canon lens? I saw it online, i think it is a little expensive for me .
I wanna to know your review on it , let's us talk about it .Is it the best lensIs it suitable for wedding ??

It is a good lens for a crop body camera (rebel/xxxD, xxD & 7D) although there are cheaper alternatives that give just as good image quality - Sigma 10-20, Tokina etc.

Not great as a wedding lens though, it'll get some wide shots if you are in a bit of a tight space and it is great for landscapes/urban stuff but for weddings, no. I take my Sigma 10-20mm with me to weddings and it almost always stays in the bag. If it is a lens for a wedding that you are after, look at 17-55 kind of range on a crop camera or 24-70 range on full frame.

What do you think the ratio of professional photographers to enthusiasts is at an average wedding? 1 in 50 maybe?
You Certainly have have no business making that assumption...

He didn't say he was going to be a professional photog at the wedding....

Most any lens can be used for weddings. Depends on your style of shooting and what you're trying to accomplish. If this is your only lens, absolutely not. But it can be used in combination with other lenses. I know plenty that use it.

You have to work with a lens to understand it's dynamics. Practice with it and once you know when and when not to use it take it to a wedding and use it selectively.

Learning how best to use wide angle lenses is important. A bit different than lenses in the more normal optical range. The 10-22mm is an excellent lens ... as mentioned there are alternatives out there.

It's not a valid assumption to think the OP is shooting professionally, but the comment isn't wrong through. If I heard my photographer say that he'd be fired on the spot

There's a distinction between "shooting weddingS" (note the plural) and shooting a friend's or family member's wedding. In the first case, this would probably imply an inventment with a (semi) professional intent.
However, since OP stated "suitable for wedding" (no plural), I will agree that I may have jumped to the conclusion that this was yet another "I have a rebel and want to make money by shooting weddings what should I get?"-topic.

A more useful answer:
While the 10-22 CAN certainly work for weddings, I wouldn't recommend you use it as your only lens. A faster lens in the normal range like the 17-55 2.8 IS will probably suit you better.
If you are looking for something in the ultra-wide range, the Tokina 11-16 can do a bit better indoors, but it's a very limited range. Something fast like a Sigma 30mm 1.4, Sigma/canon 50mm 1.4 will also be a very useful tool for shooting indoors.
On top of a lens, consider a good flash as well (580EXII or 430EXII). I'd also suggest learning how to bounce and mix it with ambient light.

If you still want some wide angle shots, the 17-55mm f/2.8 IS is good. If you need less of the wide angle and a bit more of the other end, the 24-70L is good. I personally would not recommend a flash because sometimes the flash is a bit obtrusive if you know what I mean

I would definitely have the 50l on hand for a wedding.

I never shot a single wedding, but I'd not use it as my only lens, and if a 10-22 is already stretching his budget, I'm pretty sure a 50L would be overkill.

OP, what's your lens/bodies collection?
