CANON 4K UHDxs CJ12e 4.3B WIDE-ANGLE LENS
This 4K portable wide-angle lens combines the ability to provide superb optical performance that supports 
4K UHD broadcast production with an amazing 4.3mm wide angle capability that is ideally suited to creating 
panoramic 4K imagery.
WORLD’S FIRST* 2/3-INCH 4K WIDE-ANGLE 
PORTABLE LENS
This lens boasts the world’s shortest focal length of 4.3mm* and the 
world’s shortest minimum object distance (MOD) of 30cm*. This makes 
it possible to create images having very wide angles of view with the 
shortest focal length for a 2/3-inch 4K lens: as such, this supports 
subsequent 1920 x 1080 cropping from the 3840 x 2160 camera output 
providing full HDTV quality. Alternatively, the camera output can be 
downsampled to provide an even higher HDTV image sharpness. 
APPLICABILITY AND EASE OF OPERATION 
IDEALLY SUITED FOR 4K SHOOTING
Since the lens achieves the zoom ratio, focal length, servo speed and 
stability required of wide-angle lenses, it meets the needs of a wide 
range of shooting conditions and provides the applicability and ease of 
operation ideally suited to 4K shooting. Shoulder mount lens-camera 
operation is facilitated by the remarkably low 4.63 lbs. (2.1kg) weight of 
the lens.
ACHIEVES 4K OPTICAL PERFORMANCE EVEN 
WITH THE BUILT-IN 2X EXTENDER
Thanks to the precision of its high-grade components and assembly, 
the lens achieves high 4K camera performance even when the built-in  
2x extender has been engaged.
COMPATIBILITY WITH HD LENS SYSTEMS
The lens enables the use of the same Canon standard controllers for 
zoom and focus as well as servo modules currently used by HD portable 
lenses. It comes with a 20-pin connector that enables high accuracy 
digital positional information of zoom, focus, and iris to interface with 
external virtual systems.
4K OPTICAL PERFORMANCE
This lens achieves optical performance that supports 4K cameras all the 
way from screen center to the edges.
