Economical 4K Production

The SK-UHD4000 is the world's first UHD camera to employ industry-standard B4 bayonet lenses. Broadcasters, rental houses and mobile sports trucks have huge investments in existing B4-mount HD television lenses. A 4-port prism design with 4) 2/3 inch sensors, delivers the deep depth of field, high sensitivity and low noise needed for demanding studio and live production.

Maximizing workflow options, the CU-UHD4000 incorporates 12G SDI output with HDR and Wide Color Gamut. Simultaneous HDR and SDR outputs have individual adjustments. The CCU can also output UHD HDR and simultaneous SD SDR.

Features & Functions

  • Employs B4 [BTA S-1005A] 2/3-inch industry standard lenses.
  • B4 lenses have a standardized image size, flange-back distance and electrical interface.
  • Compatible with existing and future HDTV broadcast, bayonet mount lenses from all manufacturers.
  • Allows 4K productions using HD B4 mount optics without any sort of attenuating adapter.
  • Unique Hitachi 4 port prism best preserves the lens MTF (Modulation Transfer Function) that provides the maximum contrast in 4K images.
  • The camera's optical block employs 'dual-green' and 'pixel offset' technologies to dramatically increase resolution in the Y (luminance) channel.
  • See details of Hitachi's unique 4 port imager system.
  • Hitachi's advanced digital signal processing (DSP) creates ultra-high resolution images.
  • Provides independent cut-out of HD SDI image from 4K raster that can be re-framed in real-time.
  • Functions as a normal HD (1920x1080/60p) camera while recording 4K in real time.
  • Employs the NEW HITACHI RLAC (Mutli-dimensional Real-time Lens Aberration Correction) system that eliminates most lenses' lateral chromatic aberrations.
  • Employs the latest generation of CMOS sensors.
  • High Signal to Noise Ratio of 62dB (HDTV).
  • High sensitivity of F8.0 is achieved in full UHD [3840 ? 2160/59.94p] progressively scanned image.
  • Super-sampled 1920x1080 HD-SDI outputs (down-converted from 4K) offers superb picture quality.
  • Retains a faithful 4:2:2 color space at 10-bits/sample.
  • Camera head power consumption: <38W.
  • Employs existing SMPTE-304/311 Hybrid fiber cable and connectivity.
  • Two HD (2K) progressive outputs directly from the camera head.
  • Production/Engineering intercom and Returns' embedded audio can be mixed L/R in headset
  • AC Power + Digital and analog teleprompter outputs at the camera head


  • Available Studio Adapter for use with all broadcast long box, compact studio and hand-held 2/3-inch bayonet lenses.
  • Cable-less Studio Adapter interface allows maintenance and trouble free operation and reliability.
  • Maintains backwards compatibility with existing HITACHI HDTV control panels, cables, and viewfinders.
  • The SK-UHD4000 is a perfect drop-in replacement for existing HD studio and field production cameras.
  • Ethernet control and assignment of control panels and CCUs [camera control units].
  • Ross Dashboard™ networked camera control
  • Operates over lower-cost, single-mode, fiber cable without additional external hardware or cable adapters.
