I use almost everytime the lowest ISO (100, 200, 400), 50/fps because I record 25 frames. If I record at home, always I have noises especially in the shadows. My lens: Canon 24-105 f4 and Samyang 24 f/1.4
Really strange. I was thinking if I use low iso then there can not be graines and noises, but I was wrong. Even with 100 ISO I have noises (in the dark room). I would like to record dark rooms with small lights, so it’s really problematic.
