nice! my wife does wedding photography and we just upgraded to the 5d mark II with the 16-35L f2.8 and 24-70L f2.8. we were originally going to get the 7d but after researching i figured if we were going to pull the trigger might as well go to the full size sensor of the 5d. i was really impressed though with the 7d as well.
Had considered 1.3 or full sensor but I needed the reach of the 1.6 . Like to handhold so 400 5.6 is ideal for me. 5d II is a great Full frame camera and lenses you mention also rock for weddings and scenerys !
