Small and fast, the 21mm Compact High-Speed Cine Lens covers APS-C and Four-Thirds format sensors. The lens comes in a Sony E-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.

This 21mm lens produces 69.3° AOV when used with APS-C cameras; however, even though it has a Sony E-mount, it does not cover full-frame sized sensor. Internal focus design and a non-rotating front enables using it with a wide variety of cine-style accessories. The lens features low chromatic aberration and has a minimum focus distance of just under 12" from the lens. A removable petal shaped lens hood provides flare protection when shooting without a matte box, and the lens's threaded front accepts a 58mm filter ring.
