expressP2 card

The AJ-CX4000GJ new-generation Camera Recorder responds to the emerging needs of

the broadcasting industry, such as high-quality 4K recording and network distribution,

while retaining the broadcast-standard B4 lens mount and shoulder-mount design.

The large-size 11.14 M-pixel image sensor provides a high horizontal resolution of 2000

TV lines for recording of 4K/HDR images. A nimble workflow can be realized by using

the HEVC codec for high-efficiency 4K 10-bit recording and the expressP2 card with

high transfer speed. What’s more, the HD direct streaming function that enables live

streaming to social media and the NDI|HX-compatible*1 IP connection function offer

innovative networking solutions.

The AJ-CX4000GJ also supports the AVC-ULTRA codec*2 used by the P2HD

Series to permit smooth linkage with existing HD broadcasting systems.

It provides advanced support in various applications such as broadcasting

or recording sports events and in the production of documentaries.

*1: NDI|HX, a technology of NewTek, Inc. To use this function, an activation keycode from NewTek is required.
*2: Use an expressP2 card or a microP2 card for recording in P2 format. Conventional P2 cards can not be used.
AVC-Intra200/100/50 codec will be supported in the future with the firmware upgrade.

High-Quality 4K & HDR Pictures with 2000 TV Lines and a Wealth of Camera Functions

Large Sensor and Optical Magnifying System
Achieve High-Quality 4K/HDR Shooting

2/3-type

Lens Mount

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. If designed 4K image sensor with a
2/3-type size, the pixel size is reduced from the 5.0 microns of HD to

2.5 microns, thereby lowering the image quality and sensitivity.
An optical magnifying lens allows the mounting of a large sensor on a
2/3-type lens mount.
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 newly developed 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.

HDR Shooting 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.

* 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.

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.

2.4-Type Black-and-White Organic EL Display

The 2.4-type black-and-white organic EL display offers high

brightness and clearly shows the status information even in outdoor
environment, such as the timecode and audio input level.

High Picture Quality with Shooting Assist Functions

• 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.

•

Mode Check: Displays a list of the camera settings on VF and LCD.

•

Rec Check: This lets you run a quick playback check of the clip-end.

• User Buttons: Functions can be freely allocated to the five User

buttons.
