I have a Canon Rebel T6 that I'm going to use to film a video for a class, and when looking up instructions, a website recommended that I turn off auto-focus and image stabilizer. I know auto-focus is frustrating and not very helpful so I always have that off, but why do I need to turn off image stabilizer? If I don't, in what ways, if any, will it affect my video?
Because normally you will use a tripod (where you would turn of IS/OS/VR every time) or you want to hold the camera and move around. And at the second option the problems with IS/OS/VR begins, because the stabilization will try to stabalize as long as possible for one position, which leads to the problem, that the image will jump jump jump from fixed position to the next and you will not get a smooth transition.
