overview

With a focal length range of 30-300mm, the 10x cinema zoom lens is designed to cover the longer end of the focal lengths typically required by cinematic productions, and its maximum telephoto length of 300mm puts it among the best in its class. Maximum aperture is a relatively fast T2.95 throughout much of its range, and the 11-blade iris enables a smooth bokeh for out-of-focus areas of the frame.
The lens was designed with working professionals in mind, with easy-to-read focus, zoom, and iris markings engraved into angled surfaces on both sides of the lens, so you can read the setting from either side of a camera – or from behind it. Depending on the production's needs, focus markings can be switched from standard to metric. The lens facilitates manual operation that's subtle, smooth, precise, and repeatable. Control rings are designed to provide and maintain the proper amount of resistance so you can operate with a consistent torque. The focus rotation angle is about 300°; for zoom, it's approximately 160°.
