Hi, I'm Aniruddh from New Delhi, India. New to the world of videography/photography and i just bought a fujifilm xt-200 with a kit lens (XC15-45mm/f3.5-5.6 OIS PZ) to get started. I have been trying to shoot video and needed some help from experienced users so posting my question here. What is the difference between shooting video with the dedicated movie mode or by using the video record button in any of the other modes (P,S,A,M)? I have noticed that while shooting video in M mode, the camera is using the movie ISO setting rather than the ISO set by me in the M mode. This leads me to wonder whether the other settings (aperture & shutter speed) made by me in M mode are being used at all? Also, is there a way to check manual focus in movie mode by zooming into the subject? Somehow, I'm able to do this in M mode but not in movie mode. Appreciate any help that i can get. Thanks
