Canon 4K UHDxs CJ20e 7.8B Zoom Lens


This portable 4K lens offers an overall optical performance that will support a broad spectrum of program production genres for UHD broadcast television. Featuring a 20x zoom ratio, the CJ20ex7.8B 4K lens can achieve panoramic vistas and finely detailed close-ups that are central to evocative image making and powerful storytelling when captured in 4K UHD.

Superb Optical Performance
The lens optimizes all of the optical parameters that combine to produce amazing overall image performance – namely, sharpness, contrast, colour and tonal reproduction. At the same time the optical design significantly minimizes the various monochromatic and chromatic optical aberrations that can mar an image.

Applicability and Operability Ideally Suited To 4K Shooting
This long 20x zoom lens has a remarkably low weight of 2.18 kg – a combination that greatly empowers all forms of field production. The now well-established digital drive unit adds to that empowerment wby providing precision operational control and also programmability options for the same. The focus rotation angle has been carefully designed to further support rapid focusing of distant subjects.

High Zoom Ratio and Frequently Used Focal Length
The lens has a high zoom ratio of 20x that extends from the wide end of 7.8 mm to an impressive tele end of 156 mm, covering a popular zooming range that meets multiple applications.

Superb Optical Performance, Even with the Built-In 2x Extender
With its high-grade optical components and precision optomechanical assembly, the lens maintains 4K optical performance when the built- in 2x extender is switched in.
* The FPM-420D focus unit is not supported.

Compatibility with HD Lens Systems
The standard zoom and focus controller systems currently used with Canon HD lenses are fully compatible with this new 4K lens*. The latest digital drive units that have proven to be so popular with users of Canon HD lenses are deployed with this new lens. Three high-performance encoders (which read out high-accuracy positional information of zoom, focus and iris) are featured, and Connectors provided on the digital drive unit deliver precision digital information to support virtual systems. When this 4K lens is used with standard HDTV cameras, there is higher image sharpness and minimized optical aberrations.
