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.
First Camera / Beginner Photography — EOS R100 (2023): The R100 does the basics well at the lowest possible price point. Its main value is as a gateway into the Canon RF ecosystem — the lenses you buy now will work on any Canon body you upgrade to later. Modest ambitions, reliably met.
Professional Hybrid Shooters, Portrait & Wildlife — EOS R5 (2020): A landmark camera — 8K video and 45MP in one body set the standard for what mirrorless could be.
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
EOS R100 (2023)
- First-time camera buyers stepping up from a smartphone
- Students and hobbyists wanting an affordable starting point
- Anyone who wants to start investing in Canon RF glass on a budget
- Casual photographers who don't need advanced video or speed
EOS R5 (2020)
- Professional photographers who need both resolution and video in one body
- Wildlife and sports photographers who want top AF with 20fps burst
- Hybrid shooters who need 8K or 4K/120p alongside high-resolution stills
- R5 Mark II buyers on a budget — the R5 still delivers exceptional results
