GearScore™ Verdict — Which should you buy?
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.
Professional Sports, Wildlife & Action Photography — A9 (2017): The camera that changed professional photography — the A9's 20fps blackout-free burst and silent shutter proved mirrorless had definitively surpassed the DSLR.
