NEW BCTV LENSES DESIGNED TO ACCELERATE THE PACE OF
4K UHD CONTENT CREATION
As 4K continues its steady integration into mainstream television dramas, documentaries and movies, Canon has worked to be
at the technological forefront with our innovative Cinema EOS series and development of 4K Optics. The needs of broadcast
television producers to achieve the high image quality of 4K UHD and more powerful ways of expression are now spreading to
live telecasts of sports, concerts, and events. The imperative need for 4K lenses that can offer the long focal ranges that are
central to contemporary sports coverage while maintaining the usability and ease of operation that the broadcast industry
favors, is increasing at a rapid pace. In response to these new marketplace needs, Canon is offering lenses whose performance
neatly dovetails with the various new 2/3” small-format 4K UHD cameras as part of our onward drive to support this new
movement. By offering lenses that fit in with the applications and objectives of users, Canon is taking steps to actively open up
new dimensions of potential in video performance. 4K images can convey such a sense of presence and an almost 3-dimensional
feeling that viewers sense they are actually involved in the action; through such images, these lenses can impart new values to
user content and allow viewers to experience videos in new and fresh ways.

SHARPNESS AND MORE
In all the color channels of red, green and blue, it is a matter of course that the sharpness expressed by the balance between the
high resolution and contrast is high while chromatic aberration that tends to cause the image quality to deteriorate is definitely
minimized, the ability to reproduce the colors is enhanced, and high-quality images are obtained. This is the approach that Canon
takes to deliver a 4K optical performance.
