GearScore™ Verdict — Which should you buy?
Video, Filmmaking & Hybrid Shooting — GH5 (2017): The GH5 redefined what a consumer video camera could do — 4K/60p and 10-bit 4:2:2 internal recording made it the independent filmmaker's tool of choice for years.
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
GH5 (2017)
- Independent filmmakers who need 10-bit 4:2:2 internal recording without a dedicated cinema camera
- YouTube creators who want 4K/60p, a fully articulating screen, and unlimited recording
- Photographers who shoot primarily stills but need serious video capability as a second
- GH4 owners who want 4K/60p and 10-bit — a significant step up
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
