Thanks for sharing your shots, both of you!
I've used my 24-105L, 70-300 non-L, and 100L for video; I'd use my 24IS, but it's just too damn wide on FF, though a 35IS or 50IS would likely get a ton of use.
But what I've found is this- the 'best' focal length range for most DSLR video is the APS-C 18-200 range and the corresponding FF 28-300 range. I used my zooms both indoor and outdoor, tripod mounted, monopod mounted, and hand held, and I've found that I'd need both of them to really cover most video successfully. 70mm isn't wide enough on FF, and 100mm isn't long enough, for sure, and there doesn't seem to be any hurry to make zooms that cover that range, outside of the super-zooms, most of which are awful outside of Canon's L above.
Here's where I'm going with this- on the 70D, the 18-135 is currently far and above the best video zoom, given it's consistent if uninspiring resolving power and useful zoom range. If Canon were to produce an 18-200 IS STM, that'd probably replace the 18-135 for video, assuming they improve the optics over the current model far more than the 18-55 STM and 18-135 STM did over their predecessors.
But when DPAF makes it to full-frame, the 28-300L looks like the ringer. And hell, if the focus ring is reasonably amenable to video (the 100L's is NOT), I could probably employ the lens usefully on my 6D in the interim, and if I picked up a 70D, I'd still find it extremely useful there too, when the size and weight isn't a consideration, over the 18-135.
