The AJ-CX4000 4K HDR ENG camera responds to the evolving needs of the professional broadcast industry, delivering high-quality imaging performance and advanced workflow compatibility while retaining a broadcast-standard B4 lens mount and a comfortable shoulder-mount design. As the newest model in the CX Series camera lineup, the CX4000 offers many of the same features and formats of the AG-CX350 handheld camcorder, and its larger shoulder-mount form factor allows it to incorporate the breakthrough imaging innovations, such as LSSIEL technology, found in the AK-UC4000 studio camera.

The fusion of high-quality 4K HDR video sensor performance, ISO recording ability, IP connectivity, and field-tested reliability make the AJ-CX4000 an ideal camcorder for use in a variety of industries. 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
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, a 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.

Interchangeable B4 Lens
The proprietary optical magnifying system has enabled the use of broadcast-standard B4 lenses with a large sensor while retaining the deep depth of field of 2/3" lenses. The AJ-CX4000, like it's AK-UC4000 studio camera counterpart, utilizes the revolutionary LSSIEL technology. With LSSIEL, 2/3" lenses can be used on the camera without the need for an external adaptor. The internal lens has been specially designed for large sensors, ensuring high-video quality. Like the UC4000, the CX4000 also utilizes a large format sensor. This allows the camera to realize high-definition resolution, high-sensitivity, low-noise, and a wide dynamic range.

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.

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.

Support expressP2, microP2 & SDXC Cards
The AJ-CX4000 is equipped with 1 x expressP2 card slot and 2 x microP2 / SDXC card slots. ExpressP2 cards are recommended for applications that require highly-reliable storage media, 4K large-data recording, and high-speed footage offloading. MicroP2 / SDXC cards are an economical choice and provide additional recording options. With the dual microP2 card slots, unlimited relay recording3 and simultaneous recording options are available for enhanced recording reliability. Additionally, pre-REC, interval REC, and metadata recording functions are available.

Recording Formats
The AJ-CX4000 is capable of recording in various formats at different compression rates, such as HEVC and MOV/P2 MXF4 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, provides smooth video playback on a PC, laptop, or MacBook5.

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.

Super-Fast Media Offload
Using the AU-XPD3 Thunderbolt 3 drive in conjunction with B-series expressP2 cards, media offload is faster than ever. Six hours of 4K (HEVC100) content can be offloaded in just five minutes!

Network Connectivity with LAN
The AJ-CX4000 features a built-in LAN terminal with a lock mechanism, enabling reliable network connectivity and IP remote control.

Camcorder for the NDI Ecosystem
There is an optional NDI|HX6 upgrade available for the AJ-CX4000 shoulder-mount camera, making it available as an NDI video source for use with NDI compatible switchers such as the AV-HLC100 Stream Studio, Tricaster devices, and software-based switchers such as VMIX and others. NDI|HX mode allows video transmission and camera control via IP connection without using an external converter. When connected to an NDI video switcher system, along with Panasonic PRO PTZ robotic cameras, the CX4000 becomes an integral part of end-to-end live event video productions and live streaming workflows.
