Canon confirmed development of an 8K camera system, two new 4K lenses and a new imaging sensor, among its announcements as it kicks off Canon Expo in New York.

The two new long-zoom 2/3-inch 4K field lenses are created for 4K Ultra HD broadcast camera systems, for uses including coverage of sports, concerts and other live events. The company reported that the UJ86x9.3B (UHD-Digisuper 86) will be positioned as its flagship premium 4K field lens, and the UJ90x9B (UHD-Digisuper 90), its standard 4K field lens. With zoom ratios of 86x and 90x, the UHD-Digisuper 86 and 90 lenses are scheduled to ship in October and March, respectively.

The developing 8K system currently includes a Cinema EOS 8K camera and 8K reference display, along with a related still-image single-lens reflex camera equipped with a CMOS sensor.

Canon had already been working with 8K, having previously developed an 8K lens that has been used by Japan public broadcaster NHK, which aims to launch 8K broadcasting in Japan. These broadcast trials are scheduled to begin in mid-2016 with the Rio Olympics.

With the 8K camera system, Canon said it aims to offer “not only the input and output of 8K video content, but also such processes as 8K to 4K down-conversion and 4K cropping.” The company reported that its being developed with a Canon Super 35 mm-equivalent CMOS sensor that makes possible 8,192 x 4,320 pixel imaging, at a frame rate of up-to-60 frames per second with 13 stops of dynamic range. Current plans include an EF lens mount.

Also future technology, Canon revealed that it's developing a CMOS sensor that's smaller than the size of a 35mm full-frame sensor and incorporates approximately 250 million pixels (19,580 x 12,600 pixels). According to Canon, video footage captured by Canon’s prototype camera outfitted with the sensor was “approximately 30 times that of 4K Ultra HD video." The company is  considering the application of this technology in industrial equipment.
