FX3

Name: FX3
Brand: Sony
Availability: InStock

The Sony FX3 is the most compact camera in Sony's Cinema Line — pairing the 12.1MP full-frame stacked BSI sensor of the A7S III with a cinema-focused body featuring a built-in fan, top XLR handle, and S-Cinetone colour science. Capable of 4K/120p and 12-bit RAW output, it is the go-to cinema camera for run-and-gun filmmakers who need professional image quality without a large rig.
