WHat are canon’s UHd lenses?
The breakthrough optical designs of Canon’s HD lenses do full 
justice to UHD imagery, having four times the spatial resolution 
of HDTV. The associated stunning image sharpness is created 
by the combination of the remarkable contrast that Canon’s 
multilayer optical coatings provide, and superb resolution from 
the central picture region out to the image extremities.
Canon’s UHD Series Lenses are the most high performance 
lenses among Canon’s BCTV lenses, featuring Canon’s latest 
optical designs that do full justice to 4K imagery with four times 
the spatial resolution of HD. Canon’s proprietary optical coatings 
facilitate the vibrant color reproduction expected from the  
UHD wide color gamut specifications, while simultaneously 
providing excellent tonal reproduction.  A variety of proprietary 
design techniques helps ensure preservation of these 
performance levels across the entire focal range of these 
remarkable zoom lenses.
WHat is “4K PremiUm”?
“4K Premium” refers to the flagship line of Canon’s UHD series 
lenses that exceed standard 4K optical quality expectations. 
Specifically, the central image sharpness is extremely high and 
traditional optical aberrations are virtually invisible. The very 
high contrast ratio helps produce deep rich black levels and 
superb reproduction of scene detail in shadowed areas. This 
lens is ideal when used in an HDR (high dynamic range) and WCG 
(wide color gamut) 4K UHD image acquisition system.
