The design incorporates floating lens elements allowing topreserve high image quality with minimum focusing distance. The focus ring features toothed rings compatible with professionalgeared follow focus systems available in the film industry and likewise atoothed, decoupled (de-clicked) aperture ring. Such modifications allowfor smooth and precise control over focus and aperture during videorecording / filming.
