New 20mm L-Series hybrid lens featuring an iris ring for manual iris control in videos and now stills when using the latest EOS R5 Mark II, or EOS R1 Mirrorless Cameras. A Nano USM is used for floating focus and a Voice Coil Motor (VCM) for rear focus which allows for quiet independent or synchronized actuation at high speed, great for video. L-Series level durability and weather-resistant construction for use in harsh environments helps ensure reliability and dependability. Equipped with an Iris ring to allow better operability when shooting movies, providing functionality similar to our Cinema lenses. Air Sphere Coating (ASC), and Subwavelength structure coating(SWC) helps to significantly reduce lens ghosting and flare.
