The portable CJ12ex4.3B 4K UHD wide-angle lens combines the ability to provide outstanding optical performance that supports 4K UHD broadcast production with amazing 4.3mm wide angle capability that is ideally suited to creating panoramic 4K imagery. Wide angle shooting has added tremendous creative options to many genres of program production including sports, documentaries and drama. The very nature of 4K UHD imagery inherently exploits wide angle shots by enabling panoramic vistas containing large amounts of image detail. These images can make 4K especially compelling. It is for this reason that Canon has given a special priority to bring a wide angle portable 4K lens to market in these early days of 2/3-inch 4K UHD television production. An unprecedented 4.3 mm* produces a 96-degree horizontal angle of view for the 16:9 aspect ratio of UHD.
