new camera and lens

i decided to upgrade my camera to the 40D now that the 50D is around to keep the price down. i really do need two cameras for the upcoming weddings i'm photographing, so i'm keeping the 20D too. i also realized for the weddings i need a macro lens for those close up details. thanks to my amazon.com credit card, i got a good deal on the lens and it arrived yesterday. can't wait to start using it!
