The lens is the Angénieux 24-290mm 2.8, currently at 5.6.
SORRY FOR THE FOCUS! IT IS A VERY SHARP LENS!
(the test was a quickie that's why.)
The guy is standing at an estimated 54m from the camera.
The shot is handheld because the Red ONE sliding baseplate
wouldn't fit on the Angénieux support plate (which is about 70cm
long which is very necessary to balance this setup out...
neither does it fit on my Technovision geared head, for that matter...
