The Leica 21mm T1.4 Summilux-C Lens, a product from the C.W. Sonderoptic series, excels in delivering prime optical quality even at maximum aperture settings. This cinema lens ensures broad coverage of Super 35 format without compromising clarity at the edges or leading to vignetting. It boasts a robust titanium PL mount, a precision-engineered cam-driven focus system, and consistently positioned foot-marked focus scales. The uniform T1.4 max aperture across the Summilux-C selection simplifies lighting adjustments when interchanging lenses. The construction allows non-rotating fronts favorable for fixed matte boxes and stages 300° of focus rotation for precise focus control. Integrating front filters with bespoke 92.5mm threading is permissible, and all lenses except for the 135mm exhibit a common frontal diameter of 95mm. The 21mm is relatively lightweight at 3.6 pounds and supports additional (not provided) rear net attachments.

Summilux-C lenses maintain consistent color balancing and contrast throughout various focal lengths, enabling seamless transitioning between lenses without the need to match new additions to your collection.

Color and Contrast Uniformity

Engineered with focus cams rather than a standard helicoid mechanism for enduring precision and minimal play, ensuring long-term accuracy and performance.

Cam-Driven Focus System

Optical design and the cam focus mechanism work in conjunction to reduce focus breathing, allowing for a more stable and consistent image during focus adjustments.

Minimal Focus Breathing

Tailored for digital sensors, Summilux-C lenses are telecentric, providing even light distribution across an image sensor to prevent vignetting and maintain uniform exposure.

Uniform Illumination

Combining advanced lens design, meticulous manufacturing practices, and strict quality control, the lenses offer minimal distortion, high resolution, and vibrant color reproduction with a pleasing Bokeh, despite being created using spherical elements exclusively.

Superior Optical Performance

Featuring a 300° range in focus rotation and 110° iris rotation, these lenses guarantee precise control over focus and aperture, suited for manual or automated adjustments.

Extended Focus and Iris Control

Lenses in the Summilux-C series standardize front diameters and control ring positions, streamlining lens swaps and minimizing adjustments required for lens accessories and matte boxes.
