The regular use won't care a whit about 4k vs UHD and UHD is actually better for them, if anything.
A7S+Shogun costs like 1/3 the price of a 1DC.
"You can pick an A7r up for as little as $1700 used, A7s' used for as little as $2000."
Ever wondered why these owners are selling?
A7s can't record internal 4K, and as per dpreview external isn't even cinema 4K, its UHD (max 3840 x 2160 @ 8bit). http://www.dpreview.com/previews/panasonic-dmc-gh4-sony-alpha-7s
Roger was responding to the posts about loosening the mount screws to simulate the issue. He said that loosening the screws will always cause it to happen and I agree.
And focusing speed?The 400 5.6 prime beats them all, canon 100-400, sigma zooms, whatever.
Not mine, and not the various test lenses. For all practical purposes, they are the same, except for the IS and close focusing of the 100-400.

A midrange zoom isn't supposed to "beat" a prime because unless you're focal length limited. With the zoom you can get the optimal sensor coverage meaning less noise and more sharpness because of less nr. With a prime, what do you do if your subject decides to get near you? Quickly switch to the 300L, 200L and 100L?
