AJ-CX4000: Leading the ENG Broadcast Camera Revolution

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 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.

Interchangeable B4 Lens Support with LSSIEL Technology for Better 4K/HDR Video Quality

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.

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.
