Canon CJ24ex7.5B 2/3" 4K UHD Portable ENG Lens

It is with great precision and professional craftsmanship that the CJ24ex7.5B 4K UHD Portable ENG Lens stands out as a high-quality, durable, and versatile choice for professionals in the field of electronic news gathering, documentary filmmaking, and television production. This lens is part of the esteemed 2/3-inch UHDgc series, renowned for its exceptional optical performance that meets the rigorous demands of 4K UHD imaging.

The CJ24ex7.5B lens boasts a formidable 24x zoom ratio, covering a focal length range from a wide 7.5mm to a far-reaching 180mm, and with the built-in 2x extender, this range effectively doubles to 15.0 - 360mm. This extensive zoom capability ensures that users can capture a diverse array of shots, from expansive landscapes to tightly framed close-ups, with ease and precision.

Optimized for both current HDTV and future 4K production needs, this lens is engineered to enhance HDTV optical imaging performance while also being future-proof, thanks to its ability to maintain 4K resolution across the entire zoom range and the 16:9 image plane. The lens's advanced design strategies have also expanded the optical dynamic range, catering to the latest HDR (High Dynamic Range) imaging requirements, and it supports the wider color gamut specified in ITU-R BT.2020, ensuring vibrant and accurate color reproduction.

The advanced digital drive unit of the CJ24ex7.5B lens is equipped with 16-bit encoders, ensuring full compatibility with zoom, focus, and iris controllers used with established broadcast 2/3-inch HDTV cameras. The lens's three 20-pin connectors interface seamlessly with controllers such as the ZSC-300D and FPD-400D, while also providing a 16-bit interface to virtual systems, enhancing the lens's operational capabilities.

In terms of optical excellence, the CJ24ex7.5B lens utilizes high index optical glass materials to minimize chromatic aberrations and geometric distortion. The improved surface accuracy of lens elements contributes to the enhanced Modulation Transfer Function (MTF) performance required for pristine 4K imagery. New multi-layer optical coatings and advanced deposition processes yield a deeper black reproduction, crucial for HDR content.

The lens's optimized arrangement of fluorite and UD glass elements effectively reduces chromatic aberration, thereby increasing image clarity and reducing color fringing. Special coatings, along with an internal lens barrel design that prevents reflection, result in clean black reproduction, minimal ghosting, and flaring, thus supporting high-tonality images that are essential for HDR.

Despite its advanced features, the CJ24ex7.5B lens remains compact and lightweight, weighing only 4 lbs. and measuring 6.5" (W) x 4.3" (H) x 8.7" (L). Its size is comparable to 2/3" HD lenses, yet it delivers superior 4K performance. The ergonomic design, including a comfortable grip, reduces fatigue and facilitates ease of movement, making it ideal for high-mobility shooting scenarios.

The lens's digital drive unit is designed for improved startup and mobility, providing accurate lens position data immediately upon power-on without the need for initialization. This feature is invaluable for quick shooting setups and for creating accurate composites when combining virtual and live-action images.

In summary, the CJ24ex7.5B 4K UHD Portable ENG Lens is a reliable, state-of-the-art telephoto zoom lens that delivers exceptional 4K optical performance, advanced functionality, and user-friendly operation, making it an indispensable tool for professionals seeking to capture high-quality video content in a variety of settings.
