Congrats on acquiring the 5D3! Have you tried your 35/1.4 on it yet?
Not on MY unit, but I was able to put it on a store demo unit about a week ago. To be quite honest I didn't really like the field of view on FF as much as I did on APS-C where I felt it was perfect (why I bought the lens in the first place). On FF it's a bit wide for me, prefer the FOV of 50mm. Problem is, I tried the 50 1.2 and it seemed to exhibit some backfocus at around 2.8 which I couldn't really seem to get rid of even after dialing in some AF correction quickly (and it screws up the other settings on top of that)...other than that I would certainly make the swap. I tried a used Sigma 50 1.4 which seemed great (apart from softness at 1.4), but I don't really wish to go 3rd party again and I would prefer a weather-sealed lens.
I was in the same situation as you when trying to find a FF zoom lens as sharp as my Sigma 17-50. I had both the 24-70 mk1 and 24-105. With the copies I tested, the 24-70 is sharper at f4 at all focal lengths so I ended up keeping it. One negative is that it is much larger and heavier than the 24-105. My suggestion, while you still have the 60D is to keep the 17-55 and for your 5D3, pick-up a 16-35 or another wide angle lens like 14L or 24L II first and supplement it with a 50/1.4 or 40mm (or your awesome 35L). The 16-35 will open up new creative outlets that you couldn't get before with the 60D and 24-105 or 17-55.
I guess I could do that but it's really too late on the 17-55. It's in auction on ebay (and there have been bids) so it's going to end up going to the highest bidder. I intend on getting the new 24-70 II as a replacement for use on the 5D3, as soon as my local store gets some good copies in.
I would be interested in seeing how wide 16 or 17mm is on FF...not much of a wide-angle shooter here, not really my style, but might be interesting to play around. After the 5D purchase and the 24-70 that's about it for my current funds though...so wouldn't be able to afford 16-35 or 14 (at least not right away)...perhaps a used 17-40 might be an option though- but I've heard it's not that good?
Basically, I'm only keeping the 60D for two main reasons: a) getting maximum reach out of my 70-200 2.8 and 70-300L for sports & events that call for it and b) for use with the 40mm 2.8 as a backup camera/2nd body. When I get more $ again I'll think about possibly trading in for a used 7D (much closer to the 5D3 in terms of operation it seems). The 5D3 will become my main camera with various lenses like the 24-105, 24-70 (when I get it), 70-200 and 70-300. I might trade in the 35 for a 50. that'll likely do it in terms of lenses unless I can find good deals on perhaps a 17-40 or something.
Btw, with the 24-70mk1, the 5d3's focusing points' usefulness really become apparent because you can't re-frame with that lens after focusing.
Why? Limited DOF?
