The overall demand for HD production coupled with the growing diversity of production applications has called for an expansion in the range of HD lenses. The HJ21ex7.5B was specifically developed to support high-end HD production where minimization of focus breathing (unwanted alteration to angle of view that accompanies manipulation of the focus control) & high imaging performance & extended focal range and a modestly wide angle constitute core production requirements for drama and documentary program origination. With the addition of the new digital drive unit the shooting versatility is further enhanced. The 7.5mm wide angle setting and the 21x zoom ratio offer a formidable operational combination for such high-end production work.
(New drive is loaded with the lens that has ‘A’ at the end of its model name such as ‘IRSE A’ & ‘IASE A’.)
