Whether being used for ENG, out in the field to deliver a live remote news broadcast, in a theater for live streaming a concert to YouTube Live, on a remote island to record footage for a reality TV show, or in a stadium to capture a sporting event for a documentary, the versatile CX4000 ENG camera can handle it all.


4K Sensor with Advanced Imaging Technology

Equipped with a large 11.14 megapixel MOS sensor, the AJ-CX4000 achieves 2000 horizontal TV lines with oversampling. In addition, it offers high-quality 4K pictures with low noise, wide dynamic range, dual native ISO technology for superb low light performance, and high sensitivity of F10 (59.94 Hz) / F11 (50 Hz) in High Sensitivity mode.

Brilliant HDR (High Dynamic Range)

The AJ-CX4000 features HLG (Hybrid Log-Gamma)*1 for recording HDR (High Dynamic Range) video and is equipped with the following HLG recording assist functions:

  • SDR Monitoring Gamma: Gamma curves for monitoring HLG images with the SDR viewfinder or other SDR monitor
  • HDR/SDR Parallel Output: Dual SDI can output both HDR and SDR simultaneously
  • VF/LCD HDR/SDR Selector:Assignable to the USER button for easy switching between HDR and SDR even during recording
  • Eight mode Gamma: Select from HD/SD/FILMLIKE 1/FILMLIKE 2/FILMLIKE 3/FILM-REC/VIDEO-REC/HLG gamma curves

0.005 lx of Minimum Illumination

The AJ-CX4000 achieves high sensitivity with DS gain. Combined with master gain, this enables a maximum +76 dB,*2 for ultra-high sensitive recording at a minimum subject illumination of 0.005 lx.

12G-SDI OUT Compatible with 4K 10-Bit 4:2:2 Output

The standard 12G-SDI output terminal delivers high-image-quality UHD 60p (50p) 10-bit 4:2:2 output. Also provided are XLR audio input (2CH) terminals compatible with +48-V phantom power supply as well as HDMI OUT, TC IN/TC OUT, GENLOCK IN, USB3.0 (DEVICE) and USB2.0 (HOST, wireless module) terminals.

Industry Standard Recording Formats / Editing Software Support

The AJ-CX4000 is capable of recording in various formats at different compression rates, such as HEVC and MOV/P2 MXF*3 file formats.

Using the new, high-efficiency codec, HEVC (H.265, LongGOP, 10-bit, 4:2:0, MOV), the CX4000 records high-quality 4K 10-bit images at low, 100-Mbps bit-rates. Free software, such as the VLC Media Player or QuickTime Player, provide smooth video playback on a PC, laptop or MacBook*4.

The CX4000 records MOV files that are highly compatible and easy to use. This file format is the same as that used on Panasonic's EVA1 cinema camera / AG-CX350 camcorder and supports long file names with up to 20 characters, allowing simplified video clip management. And it supports the MXF P2 file format for broadcasting, enabling AVC-Intra or AVC-LongG HD recording.

Livestream Directly to YouTube / Facebook Live

Livestreaming*5 HD video directly to YouTube, Facebook Live, and other streaming services is easier than ever with the RTSP, RTMP, and RTMPS protocol support*6 of the AJ-CX4000 camera. The CX4000 also supports multicast streaming for streaming to multiple destinations, as well as simultaneous streaming and recording.
