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.
Compact Travel & Content Creation — A7C (2020): The A7C proves full-frame doesn't have to be bulky. Excellent battery life, reliable Eye AF and a vari-angle screen in a pocketable body is a compelling combination for travel and content creators. The A7C II improved on it, but the original remains a strong value buy.
Who should buy what
EOS M (2012)
- Canon shooters who want the camera that started Canon's mirrorless story
- Budget first-time mirrorless buyers who already own EF/EF-S glass
- Collectors of significant digital camera milestones
A7C (2020)
- Travel photographers who want full-frame in the smallest possible body
- Content creators who need a flip screen and reliable Eye AF
- Photographers upgrading from APS-C who want to keep a compact kit
- Vloggers who need 4K and great battery life on the road
