Thanks for the info John, just what I was looking for and your image on the other thread is excellent.
As you say the only thing that is at the back of the mind is that if I go full frame at some stage then the lens would need to go, but only have the 7D a few months so safe for a whilke yet.
Hey Sparkie, see from the other thread that you would consider a Sigma 10-20. Me too!
In Berminghams shop in town the other day lloking at the Canon 10-22 and was very pleased with the look and feel and they even threw it on a 7D body for me. €750 blips new. They aslo have a second hand 10-20 for €400 if you are interested.
What is your opinion on the the Canon over the Sigma?
