I have had my Mkiii for a few years now with no issues. I have around 17k actuations so it is fairly new. I mostly use it for video, I would say 90% or more. Recently when I press record it stops recording after a few seconds. The sound it makes is like when you take the lens off or quick focus. I have tried different lenses, batteries, and memory cards. This happens on a tripod or hand held. This happens a few times before it stays recording. I have tried a few different scenerios like once it is recording I shake it a bit, mess with the lens, and it stays recording. It seems very random but happens at the worst times. Anyone else have this issue?
