So I am so happy with my 50mm f1.4 lens. Its a perfect lens for weddings and portrait. But on a crop sensor 400D Canon it makes it about a 80mm. So I cannot get a nice wide angle. So I have been reading reviews of the Sigma 10-20 and the guys are saying its a very nice lens for landscape and wide angle shot. So I am looking for a nice second hand one to test it out.

Here is a bit of a review.

I hope I can get my hands on one to test before I go out and spend the cash. I will keep you posted.
