I always have the EF24-70mm f/2.8 L USM on the 5D MKII at weddings. I noticed a couple of folks say they use primes at weddings, but for me, that's just a beating.I spend too much time moving to fix composition with prime lenses and for the most part my EF50mm f/1.4 only gets used on the tripod when I'm doingfixedproductshots.


For studio portraits off the tripod, the prime may be a nice lens, but I still like to recompose with the zoom.


My wedding set-up right now is as follows:


1D MKII with EF70-200mm f/2.8L IS USM


5DMKII with EF24-70MM f/2.8 L USM


50D with EF300mm f/4.0 L USM (tripod camera for the ceremony)
