4K Ultra Slow-Motion Camera
(High Frame Rate Camera)


Realize unprecedented brightness with FOR-Aʼ s new imaging system

With the adoption of our “Dual Optical Processing System”, we’ve developed a 2/3-inch sensor that makes it possible to shoot with more brightness than ever before. Our 4K ultra slow-motion camera, fully compatible with a 2/3-inch B4 mount incorporates this new technology. With no compromise in depth-of-eld zoom and focus speed, the camera is ideally for sports production. Image capture without the need for a PLB4 lens converter makes it possible to capture approximately six times brighter (2.5 stops) images than PL mount super slow motion cameras. The cameraʼs base station is a compact 2RU size, providing camera operation up to 2-km range on Hybrid Fiber cable (up to 20 km when camera head is powered locally). This ultra slow-motion camera combines a rich feature set in a cost-effective package.


  • Independent live 4K output
  • 12G-SDI/Quad link 3G-SDI outputs
  • Simultaneous record and playback with internal memory
  • Equipped with a high-speed global shutter system
  • Supports HDR and WCG
  • 24-axis color correction
  • Optional flicker correction functions
  • Improved portability thanks to a compact, lightweight design

A new imaging solution – our Dual Optical Processing System (equipped with a 2/3-inch CMOS sensor/prism)

A revolutionary new technology (patented), our “Dual Optical Processing System” achieves higher sensitivity, at higher frame rates, with high pixel density through 4K. The system uses 2/3-inch CMOS sensors to capture high resolution 4K images. The 4K ultra slow motion camera with 2/3-inch CMOS sensor has a compact form factor and produces the same image quality as a three-Imager model.    

※2/3-inch CMOS sensor/prism
   Based on this new patented technology, a unique optimized image sensor block and prism is used.                                   


Directly attach 2/3-inch B4 mount lenses

Use your current broadcast lenses as-is

  • Operate with the same 2/3-inch B4 mount lenses currently in use, with the full zoom and focus performance offered by the lens needed in sports production. Only FOR-A has achieved this in a 4K ultra slow-motion camera system
  • Box-type super-telephoto zoom lenses can be used
  • Because a PL-B4 lens converter isn’t required, there is no light attenuation

Color matching with cameras from other companies

Integrates easily into a production using standard speed cameras from other manufacturers, through pre-con gured FOR-A color matching presets.



Shoots up to 1000 frames per second (fps) in 4K

  • Shoots up to 1000 frames per second (fps) in 2/3-inch 4K UHD
  • In motorsports, capture high-definition slow-motion of not just a car movements, but also the mechanical motions and events of individual parts
  • In ball sports, capture a variety of slow-motion shots, not just of player movements but also close-ups of the ball
  • Use for line call shots in tennis and other sports judgement calls
