Small and fast, the 21mm Compact High-Speed Cine Lens covers APS-C and Four-Thirds format sensors. The lens comes in a Canon EF-M mount and features industry standard geared focus and iris rings. Ultra Multi-Coatings on the lens provide sharp contrast and consistent colors from lens-to-lens. Aspheric and extra low dispersion glass elements are used to minimize chromatic aberrations. The lens is marked in both feet and meters and features a de-clicked iris for smooth aperture pulls.
