The lens has added capability when zooming, using the QuickZoom switch. At the touch of a button, the lens can move to full telephoto in less than a second. This provides a no-hassle way of verifying focus.
High Definition Ready
Many high definition cameras are hamstrung by insufficient optics. Electronic News Gathering (ENG) lenses are traditionally built to accommodate standard definition video cameras. This lens is designed specifically with high definition in mind. The optics increase fidelity, making sure HD footage is crystal clear.
Integral 2x Extender
For instant close-up shots the lens has a switch which inserts an element that doubles the focal length at any point in the zoom range. Instead of using the zoom function the extender gives immediate close up images.
