The Mechanics of a Broadcast Lens
Broadcast lenses are generally classified into three types: studio zoom lenses, used mainly in the broadcasting studio; field zoom lenses, used for relay broadcasting of sports and other live events; and ENG/EFP lenses, used for production of such TV programs as news and on-location events.
Broadcast lenses provide high-definition 4K/HD images free from geometrical distortion and color blurring through the use of such optical elements as fluorite and aspherical lenses. Several dozen lenses are optimally configured, resulting in a broadcast lens capable of meeting the high standards of optical performance demanded by professional video production. For greater ease of use, some lenses are also equipped with high-precision position-detecting elements (encoders) and control circuits to realize superior operability.
