SK-UHD4000 Ultra High Definition Studio and Field Camera

Economical 4K Production

The SK-UHD4000 was the world’s first UHD camera to employ industry-standard B4 2/3 inch bayonet lenses. 2/3 inch sensors deliver the deep depth of field and high sensitivity needed for traditional TV studio and sports production. Additionally, broadcasters, rental houses and mobile sports trucks have huge investments in existing B4-mount HD television lenses. Many single sensor 4K TV production cameras have been prohibitively expensive due to the special lenses required.

HITACHI’s NEW SK-UHD4000 employs standard, 2/3-inch, bayonet-mount Broadcast Television Lenses which are well known as the standard in Studio and Outside Broadcast applications. The camera not only offers a pristine 4K image today but, also the best 2K, progressive images attainable with modern digital technology. It is a complete camera system that improves your current HDTV image while realizing your high-end productions in 4K.

Features & Functions

1. Employs B4 [BTA S-1005A] 2/3-inch industry standard lenses.
2. B4 lenses have a standardized image size, flange-back distance and electrical interface.
3. Compatible with existing and future HDTV broadcast, bayonet mount lenses from all manufacturers.
4. Allows 4K productions using HD B4 mount optics without any sort of attenuating adapter.
5. Unique Hitachi 4 port prism best preserves the lens MTF (Modulation Transfer Function) that provides the maximum contrast in 4K images.
6. The camera’s optical block employs ‘dual-green’ and ‘pixel offset’ technologies to dramatically increase resolution in the Y (luminance) channel.
7. Hitachi’s advanced digital signal processing (DSP) creates ultra-high resolution images from a total of 8.8 million effective pixels.
8. Provides independent cut-out of HD SDI image from 4K raster that can be re-framed in real-time.
9. Functions as a normal HD (1920×1080/60p) camera while recording 4K in real time.
10. Employs the NEW HITACHI RLAC [2- Dimension Real-time Lens Aberration Correction] system that eliminates most lenses’ lateral chromatic aberrations.
11. Designed around the latest generation of CMOS sensors.
12. High Signal to Noise Ratio of 62dB.
    High sensitivity of F8.0 is achieved in full UHD [3840 × 2160/59.94/P] progressively scanned image.
13. High resolution with 8.8 mega pixels
14. Super-sampled 1920×1080 HD-SDI outputs (down-converted from 4K) offers superb picture quality.
15. Retains a faithful 4:2:2 color space at 10-bits/sample.
16. Camera head power consumption: <38W.
17. Employs existing SMPTE-304/311 Hybrid fiber cable and connectivity.
18. Two HD (2K) progressive outputs directly from the camera head.
19. AC Power + Digital and analog teleprompter outputs at the camera head
