The SK-UHD4000 was the world’s first UHD camera to employ industry-standard B4 2/3 inch bayonet lenses. 2/3 inch sensors deliver the deep depth of field and high sensitivity needed for traditional TV studio and sports production. Additionally, broadcasters, rental houses and mobile sports trucks have huge investments in existing B4-mount HD television lenses. Many single sensor 4K TV production cameras have been prohibitively expensive due to the special lenses required.
