Canon UHD DIGISUPER 27 产品宣传册

The most advanced computer simulation design techniques, 
deployment of new glass materials and optical coatings, and new 
precision optomechanical design strategies deliver outstanding 
overall optical performance beyond 4K resolution even when the 
built-in 2x extender is engaged.  

A 2/3-inch 4K acquisition system can result in a narrower 

 

depth-of-field than an equivalent HD system, making achievement 
of accurate focus more critical. To help alleviate this challenge, the 
operation of the focusing system within the lens has been improved 
compared to previous models, which aids operational tracking  
of focus on selected scene objects even when fast zooming is  
also engaged.   

The lens has been designed with proprietary coating and 

 

anti-reflection materials to precisely manage internal light 
reflections and to better suppress unintended ghosting and flare, 
producing superb contrast and color reproduction of nominally 
exposed images.

The lens is equipped with 16-bit optical rotary encoders to 
output highly precise positional data of zoom, focus and iris on a  
20-pin connector for direct digital interface to robotic and virtual  
studio systems.

The lens utilizes the same standard controllers for zoom and focus 
operations that have been optimized over decades of Canon HDTV 
field lens developments.  Similar in size and weight to our 2/3” HD 
lenses, the UHD DIGISUPER 27 allows for the same shooting style.

CANON 4K UHD UJ27X6.5B STUDIO BROADCAST LENS

Designed for use in numerous high-end studio broadcast applications, the UHD DIGISUPER 27 combines 
outstanding optical performance beyond 4K resolution with a 27x zoom ratio (6.5mm to 180mm) and 
wide angle focal length (6.5mm at 1x, 13mm at 2x) along with easy-to-operate features.
