Is the ricoh gr iii good for video?
The site doesn't have a video review of the Ricoh GR III, but you can check it against my vlogging checklist. Its 18mm lens frames like 27mm on full frame. That's narrower than the 16-20mm I like at arm's length, so you'd be cropping yourself in tighter. On the plus side, it's small and light, and it has stabilisation in the lens or the body. The spec list doesn't mention a flip-out screen or a microphone input, so check those before you buy.
If you mostly shoot stills on the street and film the occasional clip, it's still a great pocket camera. For regular vlogging, I'd look for a camera with a wider lens and a front-facing screen. You can see the full spec list on the Ricoh GR III page.
