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.
Studio, Landscape And Commercial Photographers Needing Maximum Resolution — A7R VI (2025): The A7R VI cements its place as the resolution flagship of the Sony full-frame range — 61MP, AI-driven autofocus, and 8K video make it as capable for video and action work as it is for studio and landscape photography. The price reflects its position at the top of the lineup, but the capability is hard to match.
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
A7R VI (2025)
- Studio and commercial photographers who need maximum resolution for large prints and heavy cropping
- Landscape photographers who want best-in-class dynamic range and detail
- Hybrid shooters who need 8K video alongside a 61MP stills sensor
- Professionals upgrading from the A7R V who want faster AI-driven autofocus
Quick take: The a7r vi has the highest resolution at 61mp; the eos m is the most affordable; only the a7r vi is weather sealed. Scroll down for the full spec breakdown.
