Summary

For solo operators and nimble productions prioritizing stabilization and a compact footprint, the FX3A is the clear choice, offering 5-axis IBIS in a sub-700g body. However, for professional sets demanding integrated variable ND, robust I/O, and superior ergonomics for long shoots, the FX6 delivers a more complete cinema package.

Highlights

FX3A

  • Stabilization: 5-axis in-body image stabilization (IBIS) provides crucial stability for handheld shooting.
  • Form Factor & Weight: Extremely compact (640g) and lightweight, ideal for gimbals, drones, and discreet setups.
  • Autofocus: Features 759 phase-detect AF points for precise and reliable subject tracking.
  • Price Point: Significantly more affordable at $3898, making it accessible for smaller budgets.

FX6

  • Exposure Control: Built-in electronic variable ND filter (2-7 stops) offers seamless exposure adjustments on the fly.
  • Professional I/O: Includes 12G-SDI, Timecode, and 2x XLR inputs on the handle for robust audio and monitoring.
  • Ergonomics: Dedicated cinema body with a robust top handle and intuitive controls designed for professional operation.
  • Power System: Utilizes long-lasting, hot-swappable Sony BP-U series batteries for extended shooting.

The trade-off

Choosing the FX3A means sacrificing the invaluable built-in variable ND filter and professional XLR audio inputs. Choosing the FX6 means giving up 5-axis in-body image stabilization and a significantly more compact, lightweight form factor.
