The 16-35/4IS is my "first-alarm" lens on a 5DsR, and if I'm not shooting but my wife is, she takes it as her wide alongside a 24-105. If we're both shooting, I tend to consider whether 14mm prime is OK alongside a 24-70/2.8 II, and if so she gets the 16-35 (I tend to be a little more flexible with lens choice, plus I don't let her use the 5DsR except under well-controlled circumstances, so I feel comfortable "composing to crop" with the 14). The 11-24 is huge (quite a struggle to get it into a Shootsac, probably needs to be upside-down when in adjacent "lens slots" in our Lowepro backpacks or Pelican case, with adjacent lenses right-side up, extremely hard to get in/out of a Lowepro LensExchange case, etc.), heavy, just plain awkward, and seems to be a bit distorted at 11mm.
Too late...the 11-24L is on order and should ship out today.

I also previously owned the EF-S 10-22 and 16-35/2.8 II, and sold the latter intending to buy the 16-35/4 IS...but went with the TS-E 17 instead. Since I have excellent 17mm prime and the 24-70/2.8 II, and almost all of my travel shooting is done on a tripod, I'm not feeling like the 16-35/4 IS would add much to my capabilities. OTOH, I'm thinking the 11-24 will provide a rather unique perspective.

If I really need to 'run-and-gun' with a stabilized UWA, I've got the M2 and M11-22 (admittedly, a much slower 'gun' than my 1D X). I bring that combo for daytime walkabouts during business travel (the 1D X kit comes out at blue hour), along with the EF mount adapter so the M2 can serve as an emergency backup.

I'm not too fussed about the size and weight of the 11-24 – it may seem big and heavy, but it's tiny and light next to the 600/4 IS II that I carry around on briding walks.
