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 lens 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. 
* Among compatible 2/3-inch 4K broadcast lenses available as of August 25th, 2015.
This lens achieves optical performance that supports 4K cameras 
all the way from screen center to the edges.
