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.
Outdoor & Adventure — OM-5 (2022): The toughest camera at this price — IP53 weather sealing and 7.5-stop IBIS built for adventure photographers.
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-5 (2022)
- Outdoor and adventure photographers who need a compact, weather-sealed body
- Travellers who want MFT's compact size with pro-level weather protection
- E-M5 III owners upgrading to OM System's improved subject detection
- Photographers who want strong IBIS and rugged build without OM-1 pricing
Quick take: The om-5 has the highest resolution at 20mp; the eos m is the most affordable; only the om-5 is weather sealed. Scroll down for the full spec breakdown.
