The Leitz Cine Zoom 55-125mm Lens features a PL mount and focus scales marked in feet. This zoom lens has an image circle that covers the VistaVision format, so it will easily cover full-frame sensors. Featuring a parfocal design and a T2.8 aperture throughout its zoom range, the lens holds focus throughout the zoom and does not ramp exposure as you get to the extremes of the range. The lens design also reduces the breathing and image shift sometimes encountered while zooming and focusing. It is color-matched to Leitz primes for seamless intercutting between the lenses.
The 21-bladed iris produces attractive bokeh in out-of-focus areas, with naturalistic-looking round out-of-focus highlights. The focus, iris, and zoom control rings have cine-style 0.8 MOD gears, and the focus ring features approximately 270 degrees of rotation. The 25 to 75mm zoom features a 114mm front diameter common to many cinema-style matte boxes. The lens has a built-in support foot with a 3/8"-16 threaded mounting hole that helps support the lens with the aid of an optional 3/8"-16 rod-mounted lens support (not included).
