Designed and built to deliver optimum optical performance at wide open, the Leica Summilux-C T1.4 25mm PL Lens is part of the C.W. Sonderoptic line of Summilux-C cinema lenses. The Summilux-C lenses all feature a minimum image circle of 33mm, so they each comfortably cover Super 35 without corner softness or darkening. The 25mm focal length is a wide-angle lens found in most lens packages. It features a titanium PL mount, a cam-driven focus mechanism, and the focus scales are marked in feet. The T1.4 maximum aperture is consistent among the range, so there is no concern about exposure variations when cutting between Summilux-C lenses. Each lens incorporates geared focus and iris control rings, which share the same position, so swapping lenses can be done without having to adjust your follow focus or lens control system.
The lens features an internal focus design, which means a non-rotating front perfect for clip-on matte boxes. The 300° of focus rotation provides for accurate focus pulling, and the focus markings from 6′ to infinity are consistent across focal lengths. Front filters with a special 92.5mm threading can be mounted on this lens and all focal lengths in the Summilux-C line up, and an available rear net holder is sold separately. The 95mm diameter front is standard across all Summilux-C lenses. The 25mm lens weighs only 4 pounds.
