4K ENG/EFP zoom lens with 25x optical zoom and built-in 2x extender

A high-end 4K broadcast lens that provides outstanding optical performance to support 2/3-inch 4K cameras. Despite weighing less than 2kg, CJ25ex7.6B packs in a 25x optical zoom that starts from focal length 7.6mm and reaches up to 380mm with the built-in 2x extender. Compatibility with BT.2020 and BT.2100 enables the achievement of high quality HDR footage. The digital drive unit with a high-resolution
16-bit absolute value encoder accurately detects position information, making detailed representation of images possible and calibration easy during CG synthesis.

  • Focal length 7.6 - 190mm (380mm with 2x extender)
  • 25x zoom; 0.8m MOD
  • Weighs approximately 1.99kg (IASE S, main unit only)
  • Digital drive unit with 16-bit absolute value encoder


Micro-contrast and image quality that meet the needs of 4K

With 4K, the need for a lens to deliver high image quality is more important than ever. CJ25ex7.6B is able to resolve 4K image throughout the entire 25x zoom range. The use of low dispersion fluorite and
UD lens elements arranged in an optimal configuration reduces various types of optical aberration, resulting in amazing micro-contrast with images that appear sharp with well-defined details. Furthermore, the use of correction data (BT.2020 supported) enables optimized chromatic aberration correction, resulting in HDR/WCG-ready images that are clear and richly-toned from the center to the peripheries.

Compact and lightweight with 25x zoom, built-in 2x extender

Compact, lightweight and reliable, CJ25ex7.6B enables the excellent mobility necessary for shooting news and documentary footage. 4K camera performance, a high-magnification 25x zoom range, as well as a built-in 2x extender that realizes a focal length range of 7.6mm (wide-angle end) to 380mm (telephoto end) are packed into a light, compact body that weighs under 2kg.

Maximum accuracy with on-board high-performance digital drive unit

Precise focusing and fast, stable zoom speed is possible with the on-board information display of the full-featured digital drive unit. An ergonomically-designed, easy-to-hold grip alleviates strain caused by long hours of shooting. The 16-bit output absolute value recorder eliminates the need for initialization, enabling aberration correction and lens positioning detection from the moment the camera is powered on. Precise footage production, especially of virtual footage, is possible with the highly-precise 16-bit zoom and focus positioning data. Three standard 20-pin connectors ensure that users can access the virtual terminal even in full servo set-up.
