GearScore™ Verdict — Which should you buy?
Hybrid & Video — S1 II (2025): The S1 II is the full-frame L-mount hybrid camera Panasonic's system has been waiting for — phase-detect AF, 4K/120p, class-leading IBIS, and a professional build in one complete package. It addresses every weakness of the original S1 and positions Lumix firmly back in the conversation for serious hybrid shooters.
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
S1 II (2025)
- Hybrid photographers who need excellent stills and serious video capability
- Video professionals who want full-frame quality with 4K/120p
- Landscape and portrait photographers who want maximum stabilisation
- L-mount system users upgrading from S1 or S5 II
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
