GearScore™ Verdict — Which should you buy?
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.
Travel, Outdoor & Adventure Photography — OM-3 (2024): The ideal mid-range OM System camera — weather sealed, class-leading IBIS, and superb computational features in a compact body.
Who should buy what
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
OM-3 (2024)
- Outdoor and adventure photographers who need weather sealing and compact size
- Wildlife and bird photographers wanting improved AF over the OM-5
- Travel shooters who want a rugged, lightweight MFT system
- OM-5 or E-M5 III owners wanting better autofocus without going to the OM-1
