The HJ18ex28B IASE is a high definition EFP lens that brings entirely new shooting flexibilities to field production. The HJ18ex28B can extend to 500mm focal length (and to 1000mm with the extender). It has a very impressive optical speed of F2.8 up to a focal length of 286mm. The lens represents the very best in contemporary optical and mechanical design.
The lens combines creative flexibility and mobility in a portable HDTV camera system with the demanding performance requirements for high-end HDTV image acquisition at long focal lengths. The design optimization strategies include a very respectable sensitivity, maximization of image contrast, and preservation of the highest MTF over the long focal ranges.
