The L-bracket won't budge at all - but you will very likely damage your camera's lens mount. That's why big, long lenses have their own tripod mounts.
Yeah, what I was saying to use would be "the heaviest and longest focal length lens on the 5Ds(R) that they would use that way," meaning: a lens that would not have a tripod mount.
I don't have a heavy, short tele lens, or one of the heavy, new 50mm. I put on the old 28-135mm, set at 135mm with IS off. With the 5DsR in vertical, portrait orientation, using RRS' 5D3's bracket, I zoom in 16X in live view, and move the point to the top part of the frame, and then push on the camera at the top a bit to the left or right.
It fairly easily moves, which I've noticed before, when we give it a nudge, and this doesn't happen when in the horizontal, landscape mode. But I don't think it's a problem, even in wind. It seems to be built just about stout enough, but not too stout to be unnecessarily heavy. I have yet to see a real-world situation where it's not stout enough. But I have noticed there is some flex when we touch the camera in portrait mode.
The 1DX is not only heavier, but also taller vertically, so it will put more torque on the mount when positioned vertically in portrait mode.
The 5Ds is still lightweight, like the 5D3, so I don't see the need for anything beefier, for most uses.
I doubt if most shooters would see an advantage from getting the upcoming, heavier mount for the 5Ds.
