When I shoot video with my 1D X I sit it on a Manfrotto MVH502AH - a head which I love. As this head is designed more for video cameras, rather than DSLR, if I put the plate on the body it means I cannot properly tighten the plate into the head. It does tighten, and there is little risk to the camera, but the knob for doing so hits the base of the camera which means you cannot tighten it as much as you might like. If I put the plate on the tripod foot (I normally shoot video - especially interviews - with my 70-200 f/2.8 ii) I eliminate this problem.
However, many people including a "video expert" at Cathay in Singapore, have said I should not put the plate on the tripod foot as it creates tension where camera and lens meet.
What are your thoughts on this? Surely if the camera just sits still and does not move at all (interviews) then there should not be any tension other than gravity (which would be like a monopod), and if I do need to shoot video where I move the camera (panning or whatever) then would it be better to sit the camera body on the head rather than the tripod?
Am not sure if any of that makes any sense (still not finished the first coffee of the morning!) but your thoughts and comments are greatly appreciated.
