I know at least one other person has a 7D on here
There's a new version of the firmware which gives a bunch of new features, worth a look, iv upgraded already.

Good shout! I'll give it a go when I have a bit of time :-)
Upgraded last week.
Didn't really notice that much that was different tbh :D Not had much of a chance to use my camera lately, though will be this weekend hopefully!
