High-Quality 4K & HDR Shooting
Large Sensor and Optical Magnifying System Achieve High-Quality 4K/HDR Shooting
The AJ-CX4000GJ has the Panasonic original optical magnifying system, same as the AK-UC4000 4K studio camera having good reputation for its image quality. Panasonic's unique magnified optical lens enables a large sensor to be mounted on a 2/3-type lens mount camera. AJ-CX4000GJ chooses the image sensor, which secures a pixel size of 4.3 microns to obtain a wide dynamic range and has Dual Native ISO technology to achieve low noise even in dim lighting. This system achieves the following operability and high image quality of the 2/3-type lens and 4K/HDR shooting.
- 2/3-type lens mount secures a deep depth of field.
- 11.14 M-pixel oversampling obtains a horizontal resolution of 2,000 TV lines or more.
- 4K achieves high sensitivity F10 (59.94 Hz)/F11 (50 Hz) in High Sens mode.
- HDR shooting is supported with HLG (Hybrid Log Gamma).
- A color filter achieves color reproduction that approaches the 3-chip type.
0.005 lx of Minimum Illumination, High-Sensitivity DS Gain
High sensitivity is achieved with DS gain. Combined with master gain, this enables a maximum +76 dB,* for ultrahigh sensitive recording at minimum subject illumination of 0.005 lx.
- * With super gain set at F1.4, +42 dB and digital super gain (cumulative mode) at +34 dB.
HLG*1/V-Log*2 Gamma Compatible with HDR
Equipped with V-Log Gamma*2, which has been inherited from Cinema VariCam, and HLG (Hybrid Log Gamma)*1 that allows you to record HDR (High Dynamic Range) images compatible with BT.2000 and BT.2020. It also features the following assist functions.
- HDR/SDR (V-Log/V-709) parallel output: Equipped with two SDI outputs, and can simultaneously output HDR (HLG) images and SDR images (or V-Log and V-709*2).
- VF/LCD HDR display switch: It is possible to switch the displays of HDR/SDR (or V-Log/V-709*2) while shooting by assigning it to the USER button.
- dB/ISO display switch: It is possible to switch the dB /ISO of the sensitivity display while shooting V-Log.*2
- Nine mode gamma: Select from HD/SD/FILMLIKE 1/FILMLIKE 2/FILMLIKE 3/FILM-REC/VIDEO-REC/HLG/V-Log*2.
- *1: The HLG specification was developed jointly by Japanese broadcaster NHK and the BBC in the UK. It is defined in ARIB STD-B67 and ITU-R BT.2100.
- *2: You may be required to update with the latest firmware./li>
High-Definition Touch Panel LCD with an HD720p Display Capability
The standard 3.5-type color LCD with approximately 2.76 M pixels allows for high-definition color monitoring. In addition, the touch panel makes it easy to operate the menu.
High Picture Quality with Shooting Assist Functions
- 2.4-Type Black-and-White Organic EL Display: It offers high brightness and clearly shows the status information even in outdoor environment, such as the timecode and audio input level.
- Two Optical Filters: ND and CC, have four positions each.
- Chromatic Aberration Compensation: The small amount of circumjacent chromatic aberration is compensated.
- Dynamic Range Stretcher: Suppresses blocked shadows and blown highlights to achieve a visually wide dynamic range.
- Advanced FBC: High-precision flash band compensation.
- Digital Zoom: 2x/3x/4x digital zoom boost.
- Focus Assist: “Expand”, “Peaking” and “Focus Square.”
- Shockless AWB: A smooth transition occurs when switching white balance. It is also equipped with an auto tracking white function.
- WFM/Vectorscope: Simplified display on LCD and VF.
- High-Brightness Zebra Display: The zebra pattern can be displayed in white-out areas of the viewfinder image.
- Y-GET: Measures brightness at center and displays numerical data.
- Lens Files: Stores settings for interchangeable lenses.
- Setup Files: It makes color setting easier for multiple cameras.

4K HEVC and P2HD Recording
HEVC Codec for High-Image-Quality 10-bit 4K/60p Recording at Low Bit Rates
The AJ-CX4000GJ is capable of recording in various formats at different compression rates (see the "Recording Format").
It can record 4K (UHD) 60p/50p videos in high-image-quality 10-bit on an SD memory card. Using the high-efficiency HEVC codec (H.265, LongGOP, 10-bit, 4:2:0, MOV), free software, such as the VLC Media Player or QuickTime Player, provides smooth playback on a notebook PC or MacBook.*
The AJ-CX4000GJ records MOV files that are highly compatible and easy to use. This file format supports long file names with up to 20 characters, allowing recorded video clips to be easily managed.
- * Playback may lack smoothness depending on the PC environment, such as storage and memory devices.
* Images are simulated.
P2 MXF File Formats Supported with Proxy and Shot Mark
he AJ-CX4000GJ supports the MXF P2 file format for broadcasting. Main recording with AVC-Intra or AVC-LongG codec and sub (proxy) recording with AVC-Proxy G6 codec can be recorded simultaneously. Despite the low bit rate of 12 Mbps or 6 Mbps, the proxy data has the same angle of view and resolution as the main recording, enabling highly immediate breaking news. The sub-recording gamma setting can be set to V-709 if the main recording is set to V-log, and to SDR when the main recording is set to SDR, allowing recording with and without grading in parallel. It also supports the Shot Mark function, which enables thumbnail display, playback, and upload of only the marked clips, just like a P2HD camera recorder for broadcasting
- * Proxy recording cannot be used during MOV/AVC-LongG12 codec recording, streaming, NDI® HX1, VFR, interval recording, simulcast recording, background recording and timestamp recording. Shot Mark cannot be used during MOV codec recording, interval recording and when playback is paused. In simultaneous recording mode, the Shot Mark as last clip is not supported.
