Hey guys and girls!

My lovely wife let me upgrade yesterday from the 450D that I have had for a few years to the 7D!!

So can anyone share any tips that will help me with the transition? I am planning on keeping the 450D which was probably going to have the nifty fifty on it pretty much all the time, and I'll have the 70-250 on the 7D that came with the 450 when I bought it, until I purchase better lenses.... or would it be better to switch those lenses?

Anyways, any tips are greatly appreciated
