don't worry mate, just get out there and take photos, practice makes perfect
I'm using a Cannon EOS1000d, i bought the twin lens kit so just got the standard EFS 18-55mm and the the EF 75-300mm telephoto.
Mat has the same lenses, but with a EOS400d.
On the day, i was using both, which was a bit annoying had to keep changeing for the closeups.
The best thing i've found is to shoot at the lowest ISO possible, i shot all of mine on 200.
what gear you using Pete?
