Camera Overview — AJA CION

The AJA CION is a professional cinema camera built around a 4K APS-C sensor capable of capturing footage at a native resolution of 4096 x 2160 pixels. Powered by an AJA Custom Processor, the camera records in a range of high-quality formats including AJA Raw, Apple ProRes 4444, and Apple ProRes 422, giving cinematographers meaningful flexibility across production and post-production workflows. Video output is available at up to 60fps, with supported frame rates spanning 24fps, 25fps, 30fps, 48fps, 50fps, and 60fps — covering both cinematic and broadcast standards.

All video is captured at 10-bit color depth, supporting richer tonal gradations in grading. The CION uses a PL mount, making it compatible with a broad range of professional cinema lenses. Storage is handled via AJA Pak Media, with CFast support available through an adapter.

The body is constructed from professional-grade alloy and weighs 2,900g, reflecting its studio and field production orientation. It requires external 12–18V DC power and offers an HDMI output and microphone jack for on-set connectivity. The camera operates with manual focus only and has an ISO range of 320 to 1000.

A 2.4-inch LCD monitor with 320 x 240 pixel resolution is included for on-camera monitoring.
