GearScore™ Verdict — Which should you buy?
Documentary, Portrait & Reportage Photography — Q3 43 (2024): The Q3 with the most human lens — 43mm, 60MP, and Leica rendering at its most natural and versatile.
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
Q3 43 (2024)
- Portrait and documentary photographers who find 28mm too wide and 50mm too tight
- Q3 owners who prefer a natural 43mm perspective over the iconic 28mm Summilux
- Reportage photographers who want the discreet Q3 form factor with a more intimate focal length
- Leica system users who want a fixed-lens body that excels across multiple genres
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
