Canon CJ18EX28B 2/3" 4K UHD Portable ENG Lens

Enhance your visual storytelling with the Canon CJ18ex28B 2/3" 4K UHD Portable ENG Lens, a high-quality addition to our acclaimed 2/3-inch UHDgc series. Designed for professionals who demand versatility and reliability, this durable lens is ideal for documentary, nature, and a variety of other field production genres. Its innovative engineering ensures compatibility with Canon EF mount cameras, making it a top choice for both current HDTV and future 4K production needs.

The CJ18ex28B boasts an impressive 18x zoom ratio, covering a focal length range from 28mm to 500mm, which extends to an extraordinary 1000mm with the built-in 2x extender. This feature-rich lens maintains 4K resolution across the entire zoom range and the 16:9 image plane, ensuring sharp, high-resolution images that meet the demands of modern HDR content creation.

Canon's exclusive optical design technology is at the heart of this lens, delivering 4K resolving power and high contrast from the center to the edges of the frame. High index optical glass materials are utilized to minimize chromatic aberrations and geometric distortion, while advanced surface accuracy enhances Modulation Transfer Function (MTF) performance. Multi-layer coatings ensure deep black reproduction, a key component of HDR imaging.

The lens's optimized arrangement of fluorite and UD glass elements significantly reduces chromatic aberration, resulting in increased image clarity and minimized color fringing. Additionally, special coatings and a thoughtfully designed internal lens barrel work together to reduce ghosting and flaring, supporting the high-tonality images required for HDR.

Despite its super-telephoto capabilities, the CJ18ex28B remains compact and lightweight, weighing only 6.08 lbs. and measuring 7.0" (W) x 4.8" (H) x 10.6" (L). It offers the same ease of mobility as conventional HD lenses, with an ergonomic design that reduces operator fatigue. The center of gravity is optimized to minimize strain during extended use, and the ergonomic grip ensures comfortable operation.

This lens supports the wider color gamut specified in ITU-R BT.2020, enabling exceptional color reproduction. It is also compatible with HD demand accessories, such as the ZSD-300D and FPD-400D, allowing for seamless integration with existing broadcast equipment.

The advanced digital drive unit features a high-performance 16-bit encoder that communicates with compatible 2/3" HDTV/UHDTV cameras for aberration correction without the need for lens initialization. Three 20-pin connectors provide high-definition lens output for virtual systems, enhancing operability and virtual image expression.

The CJ18ex28B's drive unit offers immediate lens position data upon power-up, eliminating the need for initialization and enabling quick start-up for shooting. This capability is crucial for accurate composites in virtual and live-action integration.

On-board display features allow for easy adjustment and operation of digital functions, including Shuttle Shot, Frame Preset, and Speed Preset. These functions enable precise control over focal lengths and zoom speeds, contributing to the creation of stable and dynamic images.

In summary, the Canon CJ18ex28B 2/3" 4K UHD Portable ENG Lens is an innovative, high-quality choice for professionals seeking a versatile, reliable, and future-proof lens that delivers exceptional optical performance in a range of field production settings.
