Features

The CJ45ex9.7B lens features an ultra-high zoom ratio of 45× and telephoto end focal length of 437mm (874mm when using the built-in 2x extender), making it ideal for shooting live sports, nature, concerts, live events and other applications where focal length on the telephoto end is prioritized. Offering a wide angle focal length of 9.7mm, the extensive focal range allows you to cover a wide range of shooting needs with a single lens, making it particularly useful for mid-sized broadcasting vans, horse racing tracks, and monitoring applications. High optical performance is maintained throughout the entire zoom range, even when the 2x extender is used.



New Integrated Multi-Group Movable Zoom for Outstanding Zoom Control
The lens features a new integrated multi-group movable zoom system, compared to the conventional two-group movable zoom system found in most broadcast lenses. This system helps provide superb zoom control, working to maintain optical performance throughout the entire zoom range from the center of the image to the edges. Integration of a multi-group movable zoom system also offers wider angle while reducing the φ127mm diameter of the front lens element that is equal to conventional HD lenses.


Wide Focus Rotation Angle
A rotation angle of 180 degrees (compared to 110 degree rotation angle of our HJ40x lenses) facilitates tight control for 4K UHD cameras , helping improve focus operation, even at long focal lengths where focusing can be difficult.

The CJ45ex9.7B lens features a combination of specialized materials, contemporary optical design and multi-layer coatings to produce outstanding 4K imagery, effectively deriving the potential of 4K cameras and expanding possibilities for image expression. In addition, 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 Integrated Multi-Group Movable Zoom System and Floating Focus System
A new integrated multi-group movable zoom system can control at points with major fluctuations in optical performance during zooming (wide middle, tele middle), working to maintain  optical performance throughout the entire zoom range from the center of the image to the edges. In addition, a new integrated floating focus system helps reduce changes in aberrations when focusing to different object distances, while maintaining 4K optical performance in color reproduction over the entire focus range, especially on the telephoto side.


Minimized Chromatic Aberration
Fluorite and UD glass have been generously utilized and optimally arranged for better correction of chromatic aberrations. This helps produce beautiful images with less color bleeding or coloring around the outlines, achieving superb color reproduction to the edges of the images. In addition, the BT.2020 compatible correction data enhances the magnification chromatic aberration correction level of the total camera system.

Reduced Ghosting
The lens coating helps to control the reflection on the lens barrel’s inner surface, helping suppress ghosting and flaring, resulting in HDR-compatible high-contrast images.

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 CJ45ex9.7B lens delivers the advanced optical performance that Canon considers essential for a HDR system, enabling shooting of more realistic images.


The CJ45ex9.7B lens features built-in image stabilization – a newly designed system compared to that in the HJ40x generation lenses. The improvement is significant in the all-important higher vibration frequency range that is typically stimulated when shooting within helicopters, boats, and motor vehicles.



Image stabilization mode settings are enabled from the digital information display on the digital servo drive unit.


Motorized Mechanical Lock Release Mechanism
A motorized mechanical lock release mechanism improves operability by enabling easy release in situations when the lever is hard to reach, such as when mounted on a tripod.

The CJ45ex9.7B lens features a high performance digital drive unit that improves servo performance compared to our HJ40x lenses, and an advanced 16-bit absolute value encoder that supports communication with compatible 2/3" 4K UHD cameras.

Quick Startup and Easy Calibration
The drive unit of the CJ45ex9.7B 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. Eliminating initialization of the encoder at power-on simplifies calibration when composing virtual and live-action images, and helps to create more accurate composites.

Fast Servo Operation
The servo operates faster than our HJ40x generation lenses, and can achieve the full focal range zoom in 1.2 seconds. The focus control has a wide 180 degree manual rotation angle, and when servo driven it can drive focus control over its full range in 1.8 seconds. The iris can be driven over its full aperture range in 1.3 seconds.



Advanced Virtual Operability
The drive unit of the CJ45ex9.7B lens uses three 20-pin connectors. This enables virtual system output and users can access the virtual terminal. One of these connectors outputs lens positional data, allowing for output even while the zoom and focus servo controllers are in use.


Simple Display Operations
An on-board information display is included on the servo drive unit that supports a range of operational settings. The digital display makes it easy to set, review and display a variety of operational functions. Full Mode can be selected, along with a simplified mode (Basic Mode) that limits options to most frequently used settings, making for easier operation.

HD Demand Compatibility
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 ZSD-300D and FPD-400D) which are currently used by HD equipment.

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.

Weighing only 12.3 lbs. and measuring 6.8" (W) x 5.8" (H) x 13.3" (L), the portable CJ45ex9.7B lens is similar in size to conventional 2/3" HD lenses, while delivering high level 4K optical performance, 45x high zoom ratio and faster servo operation. The lens is designed to satisfy professionals with its high-level combination of excellent specifications, enhanced optical performance, and outstanding usability.
