Sony 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.

GearFrame's Take

The definitive run-and-gun cinema camera — A7S III sensor quality in a body built specifically for video professionals.

⚠️ Not Ideal For

🌆

Street 4.3 Held back by portability and viewfinder. Scored down: cinema-style body. No viewfinder and video-optimised design limits street photography use.

Casual 4.9 Held back by portability and value for money.

📝 How suitability scores are calculated GearScore™ genre scores are calculated from this camera's verified specifications — autofocus, sensor, weight, weather sealing and more — weighted by what matters for each type of photography. Where a spec sheet misses something (e.g. a manual-focus rangefinder for street), we apply a documented editorial adjustment. Scores are not based on customer reviews. See our full methodology →
