Is the canon eos 6d mark ii good for video?
I don't cover the EOS 6D Mark II's video features on this site, so I can't tell you how its footage looks. The body has no in-body stabilisation, though, so for handheld video a stabilised lens helps a lot. From its lens list, the Canon EF 16-35mm f/4L IS USM is a good choice for wide handheld shots, and the Canon EF 24-105mm f/4L IS II USM works as an everyday zoom for filming people and events.
Whatever camera you use, bad audio ruins more videos than soft focus, so budget for a microphone from the start. The Video guide covers what to look for in a video camera and the audio gear that pairs with it.
