You have no idea how excited I am right now.
On Tuesday I ordered my 5D MkIV and 24-105mm F4L IS USM II. Woohoo! :-D
I'm expecting it to rock up either tomorrow or Tuesday and You can be sure I'll take a bunch of shots with the venerable 700D to a) show off the new rig and b) retire the old one.
I know it sounds a bit weird, but one of the things I'm really looking forward to is that fact that the larger body will feel better in my hands. The 700D looks and almost feels like a compact camera since I have fairly large hands, and its light weight only adds to that perception. The 5D body plus an L lens will take some getting used to, but I'm quite confident it will end up feeling more solid and 'real' fairly quickly.
Look out for the "5D unboxing" album soon!
