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.
Casual & Everyday — EOS M3 (2015): The EOS M3 was a meaningful upgrade over the original EOS M — bringing 24MP, a tilting touchscreen, and improved Hybrid CMOS AF III. Video tops out at 1080p/30p and burst shooting is modest, but for stills photographers wanting affordable APS-C quality, the M3 is a competent used-market option.
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.
Who should buy what
EOS M (2012)
- Canon shooters who want the camera that started Canon's mirrorless story

EOS M3 (2015)
- Photographers who want affordable 24MP APS-C quality on a budget
- Casual shooters who want a compact EF-M camera with a tilting screen
- Users looking for an affordable entry into the Canon EF-M ecosystem
- Used-market buyers wanting a capable but inexpensive mirrorless
PowerShot G7X Mark III (2019)
- Vloggers and content creators who need 4K video, a flip screen, and a mic input in a pocket-sized camera
- Travellers who want the best possible compact video quality without carrying an interchangeable-lens system
- Live streamers who want USB streaming capability built into a compact camera
- Smartphone upgraders who want significantly better video quality in something nearly as pocketable
