Features

The portable CJ14ex4.3B 4K UHD lens was developed using our exclusive optical design technology to achieve superb optical performance, with 4K resolving power and high contrast from the center of the screen to the edges. 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 multi-layer optical coatings combined with new deposition processes produce a deeper black reproduction that is important to HDR imaging.

Minimized Chromatic Aberration
An optimized arrangement of fluorite and UD glass help minimize chromatic aberration, increasing image clarity with reduced color fringing on edges.

Reduced Ghosting
Special coatings and an internal lens barrel designed to prevent reflection result in clean black reproduction, less ghosting and flaring, sustaining high-tonality images that support HDR.

Built in 2x Extender
4K optical performance is maintained when the 2x extender is deployed.
Weighing only 4.7 lbs. and measuring 6.4” (W) x 4.3” (H) x 9.8” (L), the portable CJ14ex4.3B 4K UHD lens is similar in size to our 2/3" HD lenses, while delivering 4K performance and offering the mobility demanded in the reporting and documentary fields. The lens features the optimum construction and high durability of a conventional HD lens, while offering the same shooting style as that of existing 2/3" HD lenses.

The center of gravity is close to the mount, lessening strain on the hands and elbows of the camera operator. The ergonomic form factor creates a user-friendly design, including an ergonomic grip design for a comfortable feel during operation, helping to reduce fatigue and make it easy to move the camera about. The lens is sure to satisfy with its high-level combination of excellent specifications, enhanced optical performance, and outstanding usability.
The portable CJ14ex4.3B 4K UHD 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. Like our UHDxs series lenses, the CJ14ex4.3B provides optimized chromatic aberration correction based on BT.2020 correction data, enabling more lifelike high-resolution video shooting with outstanding tonality, realistic texture and depth.


This feature allows for compatibility with a broadcast-use HD demand. It enables the use of the zoom and focus electrical drive system accessories (such as the ZSC-300D and FPD-400D) which are currently used by HD equipment.
The portable CJ14ex4.3B 4K UHD 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.

Improved Startup and Mobility
The drive unit of the CJ14ex4.3B 4K UHD lens 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 to create more accurate composites.

Aberration Correction and Virtual Functions Enabled without Lens Initialization
Aberration correction functions 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.

Advanced Virtual Operability and Precise Virtual Image Expression
The drive unit of the CJ14ex4.3B 4K UHD 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.



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

Image is simulated


The Canon drive unit integrates a variety of operations, stored digitally, that can be manipulated using the display.

Shuttle Shot
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 on to an object.

Frame Preset
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 pre-set 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 shot and wide shot.

Speed Preset
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 zooming out contributes to help create stable images, particularly with slow zooms.

White Papers

Role of the 2/3-inch Image Format in 4K UHD Production
This paper is intended to provide a background to the emergence of 2/3-inch lens-camera systems for 4K UHD production and the optical performance expectations of associated 4K lenses. The paper will review Canon’s involvement in the development of those lenses and will describe our initial 4K UHD lens family and the associated design strategies to achieve this impressive level of optical performance. The paper will explain the unprecedented strategy of introducing two categories within this new 4K UHD lens family – namely, 4K and 4K PREMIUM. The distinct performance difference between the two reflects Canon’s recognition that different 4K program genres will require different levels of overall cost / performance.
Lens Strategies for the era of 4K UHD Digital Motion Imaging
It was probably inevitable that broadcasters would begin to explore the possibilities of 4K UHD for the globally popular world of outside broadcast sports coverage; and indeed, recent years have seen a great deal of related experimental projects. The 4K UHD lens issue soon surfaced as the limitations of presently available Super 35mm zoom lenses quickly became apparent.
