Verdictwhich should you buy?
BF — Photographers Who Want To Strip Back Every Distraction: The most radical camera in years — no dials, no buttons, just a flat aluminium body and total creative minimalism.
FX30 — Video Creators & Filmmakers: The Cinema Line entry point — S-Cinetone colour science, 4K/120p, and XLR audio in a compact, affordable body that punches far above its price.
