Is the canon powershot g7 x mark ii good for vlogging?
The Mark II is a decent compact, but it's not my first pick for vlogging. Its 8.8-37mm lens frames like 24-99mm on full frame. My vlogging checklist suggests a wider view, around 16-20mm equivalent, because stabilisation crops in further and a 24mm view can end up cramped at arm's length. Its page also doesn't mention a flip-up screen, which is the first thing I'd want for seeing yourself. It does have a bright lens, which helps in dim rooms.
If vlogging is the goal, I'd look at the Canon PowerShot G7 X Mark III. It's described as a vlogging favourite with a flip-up screen and the same bright 24-100mm-equivalent zoom. Its zoom is still on the long side, so you'll want to frame wide. Whatever you choose, budget for audio too, as my audio notes explain.
