Capture UHD 4K footage with the 2/3" UHD XS 25x Standard 7.6-190mm Full-Servo Lens from Canon. The CJ25EX7.6B IASE S is a 25x zoom lens for 2/3" format 3-chip ENG/EFP cameras. It retains the compact, lightweight design of Canon's legacy servo lenses while weighing only 4.4 lb and improving on the zoom range and the digital drive, as well as supporting UHD 4K and HDR footage. The lens incorporates a B4 mount, standard for ENG/EFP lenses, and it features a built-in 2x extender.

Focus, zoom, and iris are all servo controlled, providing extremely smooth zoom, focus, and iris pulls The digital servo drive generation 4 unit uses three 20-pin connectors, and the encoder does not require initialization to provide high-precision encoding information for composing virtual and live-action images. The lens incorporates well-known Canon features, including Shuttle Shot, Frame Preset, and Speed Preset.

High-index optical glass materials, each having unique dispersion characteristics, help minimize chromatic aberrations and geometric distortion. Lens element surface accuracy has been improved significantly over HDTV lenses, contributing to the enhanced Modulation Transfer Function (MTF) performance required of 4K imagery. New multilayer optical coatings combined with new deposition processes produce a deeper black reproduction that is important to HDR imaging.

4K optical performance is maintained when the 2x extender is deployed.

The CJ25ex7.6B is the first UHD 4K broadcast lens in its class with a 25x optical zoom (190mm) on the telephoto end (380mm with the built-in 2x extender). Combined with a 7.6mm wide setting, the CJ25ex7.6B is ideal for a wide range of UHD 4K outside broadcast television productions, including live sports, nature, concerts, and other live events.

Weighing only 4.4 lb, the portable CJ25ex7.6B UHD 4K broadcast lens delivers the optical performance to support 4K cameras in a compact, lightweight body with the durability of a conventional HD lens. Designed to satisfy professionals with its high-level combination of excellent specifications, enhanced optical performance, and outstanding usability, the lens is ideal for on-the-shoulder shooting and interviews and offers the high mobility demanded of cameras in the reporting and documentary fields.

The ergonomically designed grip offers an excellent feel during operation and was designed to fit comfortably in the hand, easing the strain on camera operators shooting for long hours on the shoulder.

The portable CJ25ex7.6B UHD 4K broadcast lens features correction data that supports BT.2020, which offers a wider color gamut than the conventional BT.709 broadcasting standard. This enables excellent color reproduction to the corners of the screen when attached to a 4K camera, producing images that support High Dynamic Range (HDR) and Wide Color Gamut (WCG). The CJ25ex7.6B also provides optimized chromatic aberration correction based on BT.2020 correction data, enabling more lifelike high-resolution images with outstanding tonality, realistic texture, and depth.

HDR images offer excellent gradation representation and enhanced realism and dimension, including texture for image representation close to the real thing. However, there can be noticeable color bleeding and flare, so HDR shooting requires high optical performance. The CJ25ex7.6B UHD 4K broadcast lens delivers the advanced optical performance that Canon considers essential for a UHD/HDR system lens, enabling the shooting of more realistic images.

The portable CJ25ex7.6B UHD 4K broadcast lens incorporates a digital drive unit, and the high-performance 16-bit encoder supports communication with compatible 2/3" HDTV/UHDTV cameras equipped with aberration correction functionality without initializing the lens. Three 20-pin connectors enable high-definition lens output for virtual systems even during full-servo operation. In addition, the low power consumption and the simple display enhance operability.

The drive unit of the CJ25ex7.6B can output accurate lens position data from the moment the power is turned on and does not require initialization, contributing to the quick start when shooting. This is possible thanks to the drive unit's 16-bit absolute value encoder. Eliminating initialization of the encoder at power-on simplifies calibration when composing virtual and live-action images and helps create more accurate composites.

Aberration correction functions have increasingly been employed on 2/3" HDTV/UHDTV cameras for broadcast use. The associated data files are immediately transferred to the camera, which implements digital correction for the lens aberrations. The lens also delivers digital positional data for external virtual systems.

Various digital features can be set, adjusted, and operated from the display on the drive unit.

The drive unit of the CJ25ex7.6B UHD 4K broadcast lens uses three 20-pin connectors. One of these connectors outputs 16-bit high precision lens positional data, allowing for output even while the zoom and focus servo controllers are in use. This high-performance encoder helps simplify calibration when composing virtual and live-action images, thus resulting in more accurate composites.

By memorizing any two focal lengths, the Canon drive unit can automatically "shuttle" between two points, moving in either direction. As an example, this function is effective for shots in which an operator wants to start from a wide angle and then zoom in rapidly onto an object.

An angle of view can be preset in either of two memories, and the lens will zoom at the highest speed, or in a preset zoom speed, to the preset position with the push of a simple button. As an example, this function can be effective for situations such as interview programs, where it is necessary to switch between bust and wide shot.

A specific zoom speed can be preset in memory, making it possible to repeat the zoom speed as often as you like with the push of a simple button. Using a preset speed when zooming in and out contributes to stable images, particularly with slow zooms.
