Good move, saves you a ton of money! I actually purchased the 24L & 50L when Canon had a 15% off Refurbs, so ended up saving even more.
I was thinking of trying to shoot a good deal of the wedding with 24mm 1.4 on one body and 50mm 1.2 on the other, these are a couple of my top focal lengths used but at a point in my carrer some time ago i decided the image quality was excellent with the 24-70 & 70-200 and i wouldn't be sacrificing anything. Its a pain to change out lenses with a lot of primes but if i plan well it prob wont be a prob.
I guess mainly i want the images to pop more and so at $1700 not sure if that is worth it but if my clients see special work done with the lenses it may mean more work.
Still I would like feedback from some wedding people about the lens.
