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.
Entry To Full-Frame Mirrorless & Rf Lens Exploration — EOS R (2018): The RF mount's founding camera — 30MP, Dual Pixel CMOS AF, and the proof-of-concept that launched Canon's mirrorless era.
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 R (2018)
- Canon DSLR users wanting to enter the RF ecosystem at the lowest full-frame price
- EF lens collectors who want an affordable RF body to use with the EF-RF adapter
- Photographers stepping up from APS-C who want full-frame quality on a budget
- RF system fans who want a second body without full EOS R6 pricing
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
