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.
Wildlife, Sport, Outdoor — OM-1 (2022): OM System's statement camera — class-leading weather sealing and the best IBIS in the business.
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
OM-1 (2022)
- Wildlife and bird photographers who need fast burst and pro weather sealing
- Outdoor photographers who work in challenging conditions
Quick take: The om-1 has the highest resolution at 20mp; the eos m is the most affordable; only the om-1 is weather sealed. Scroll down for the full spec breakdown.
