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.
Photographers Who Want To Strip Back Every Distraction — BF (2025): The most radical camera in years — no dials, no buttons, just a flat aluminium body and total creative minimalism.
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
BF (2025)
- Photographers who find camera menus and dials a distraction from the creative process
- L-mount system users who want the lightest, most minimal full-frame body available
- Design enthusiasts who value the object quality and philosophy as much as the output
- Sigma fp/fp L users ready for a more radical step toward minimal photography
