I got a chance to shoot a wedding over this weekend. The bride contracted two photographers for this event! I actually knew the other photog and he let me use some of his glass. For the longest time I've used mainly primes for their dof and low light capability. However I was very very impressed with how the 24-70 and 70-200 handled. I used to shoot a 24-70L, but that was back on a crop body. On my D700 the AF was scary fast, silent, dead accurate. Images were surprising tack sharp in center wide open. I think I'm going to take everyone's word for it and begin with a 14-24mm then work my way up. On a side note I think I've gotten a tad bit lazier using the zooms over my primes It's nice to stand still and work my framing.
