GearScore™ Verdict — Which should you buy?

Canon Mirrorless History & Ef-M Collectors — EOS M (2012): Canon's first mirrorless — a historic body that broke new ground with touch-AF and EF-M, but its sluggish contrast-detect system quickly became its Achilles heel.

Entry To Full-Frame Mirrorless & Rf Lens Exploration — EOS R (2018): The RF mount's founding camera — 30MP, Dual Pixel CMOS AF, and the proof-of-concept that launched Canon's mirrorless era.

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.
