Vlogging, Content Creation & Travel Video — PowerShot G7X Mark III (2019): The finest vlogging compact available — pocket-sized 4K, a flip screen, mic input, and USB live streaming in one remarkably capable package.

Outdoor & Adventure — OM-5 (2022): The toughest camera at this price — IP53 weather sealing and 7.5-stop IBIS built for adventure photographers.
