Leica Summilux-C

The magic happens in the design process, where choices in coatings affect the color and contrast, where the inclusion of exotic glass elements and shapes determine the treatment of highlights and focus fall off. It happens in the mechanical design where precision machining gives each focus and iris ring its accuracy with a smooth feel and repeatable action.

Aperture

At T 1.4 the Leica Summilux-C prime lenses are among the fastest modern lens sets available, but unlike traditional lenses they are designed to perform at their best when wide open.

Focusing

The biggest complaint about 35mm cinema lenses has always been their large size intended to accommodate a focus ring with more witness marks.
The Summilux-C lenses feature a patented focusing mechanism that eschews the logarithmic focusing of the past by expanding the focus scale in the most critical range.

Size

Their unique design allows these cine lenses to be far smaller than any existing lenses below T2.0. At just 5.6” (142mm) long and weighing between 3.5 and 4 pounds (1.6-1.8kg), lens changes are easier and safer than ever, which is welcome news for camera assistants and hurried productions. Smaller lenses also result in smaller, lighter camera packages and cases as well as significantly smaller rigs.
