Video & Imaging Performance Comparison
Video Recording Capability
R5 C's 8K DCI output surpasses FX3's 4K maximum, though FX3 offers superior 120fps 1080p slow motion.
Autofocus in Video
Sony's Real-time Tracking is industry-leading for video; Canon's phase-detect AF struggles with continuous tracking compared to Sony's contrast-detection hybrid approach.
Stills Image Quality
R5 C's 45MP sensor captures higher resolution and dynamic range for photography; FX3's 12MP is cinema-focused and insufficient for demanding stills work.
Cinema Ergonomics
FX3 has dedicated cinema buttons, XLR audio inputs, and compact body; R5 C is stills-centric with less streamlined video workflow.
Low-Light Performance
R5 C's larger pixels and advanced sensor tech yield cleaner high-ISO output; FX3 is capable but shows more noise above ISO 6400.
Portability
FX3 is 88g lighter and more compact, making it superior for gimbal work, travel, and handheld cinema.
