UHK-X750

4K/HD Studio Camera System

The UHK-X750 is the flagship 4K/HD camera head for live and studio production with box lenses.
Sharing the CMOS sensor with the global shutter and the digital signal processing technology with the UHK-X700, the UHK-X750 brings
a naturalness to the uncompromising 4K image quality.
The robust housing and the optimally placed and easy-to-use switches make it comfortable for the camera operator to perform their tasks, especially live coverage with super-telephoto zoom lenses.

Newly Developed 2/3-inch Global Shutter CMOS Sensor

A 3-CMOS optical system using a newly developed 2/3-inch CMOS sensor boasts an S/N of 62dB and a sensitivity of F11 (2160/50p) / F10 (2160/59.94p) in 4K. The high dynamic range of the sensor produces high-quality images with excellent color reproduction. The CMOS sensor incorporates a global shutter pixel architecture, enabling the camera to capture natural images even under challenging situations. Still frame replay of fast-moving objects is free from geometric distortion. And there are no flash bands when the camera is shooting under strobe lights or flashes from still cameras.

  

HFR Capturing(Option)

The UHK-X750 produces highly detailed 4K/HD slow-motion images with the BSX-100/CCU-X100. Two available upgrade stages are fitting different budgets and required HFR speeds.
  Advanced HFR: 2x, 3x, and 4x speed in HD.
  Extended HFR: 2x speed in 4K and 2x, 3x, 4x, 6x, and 8x speed in HD.

OVC (Optical Vignetting Correction)

Due to the optical characteristics, zoom lenses often exhibit a roll-off around the edges of the image. Similarly, a ramping, or F-drop, a decline of overall sensitivity at the tele end is another issue, especially with super-telephoto zoom lenses. The UHK-X700 communicates with compatible lenses of the correction data and automatically compensates for the visible changes in the picture.

RBF (Remote Back Focus Adjustment)

The back focus of a zoom lens can be adjusted with the touch screen and knobs on the OCP remotely.
The adjustment is accurate and easy, even when the camera head is located in an environment where it is hard to clearly see the VF or reach the back focus knob on the lens.

16-axis Color Correction

This function independently adjusts the hue and saturation of specific colors. It permits subjective manipulation of one color without affecting the other colors in the scene.

HDR (High Dynamic Range)

The gamma setting is selectable and can be customized to create a specific tone. The “HLG“ (Hybrid Log Gamma), which conforms the international standard (ITU-R BT.2100), is pre-installed and enables more neutral image quality with high contrast for a wider dynamic range. This allows for more image information to be retained with greater headroom and color grading.

Optimal Camerawork with Box Lenses

As the VF position can be lowered and close to the optical axis of the zoom lens, the UHK-X750 provides optimal camera operation.
