Is the ricoh gr good for video?
The Ricoh GR isn't really a video camera, at least not by the things that matter for video. It has no stabilisation, and its 18mm lens frames like 27mm on full frame. That's a little tight for handheld or vlogging work, where a wider view of around 16 to 20mm is easier to live with. I don't have any details on its video modes, microphone input or screen, so I can't tell you more than that.
If you want a camera that does both stills and video, check the For vlogging checklist first. It covers the flip screen, microphone input and weight. The Ricoh GR II is the older compact here, and I'd only pick it for video if you can confirm those features yourself. The Ricoh GR page has the full specs.
