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.
Landscape, Wildlife & Professional Studio Photography — D850 (2017): The finest DSLR ever made — 45MP, 9fps, and nearly 2000 shots per charge in a body that still outperforms most mirrorless cameras for battery life.
