The Canon RF 35mm f/1.4 L VCM Lens is an entirely new L-series lens, targeting a wide range of still-image and video shooters, with a combination of very moderate wide-angle coverage, a fast f/1.4 maximum aperture, and excellent optical design. On a full frame camera this lens gives you a slightly wide-angle look which has for decades been used in photojournalism and street photography, and has become a very popular wedding shoot look. On the video side, this lens really shines with a dedicated manual Iris ring, and a new linear focus motor called a VCM (Voice Coil Motor) that is virtually silent. The VCM works in tandem with a Nano USM on the floating focus unit for incredibly fast autofocus. And finally, focus breathing is barely noticeable on this incredibly versatile lens.

• The latest L-Series hybrid lens featuring an iris ring for manual iris control during video capture.
• A Nano USM is used for floating focus and a Voice Coil Motor (VCM) for rear focus which allows for quiet
  independant or synchronized actuation at high speed, great for video.
  
• Improved durability and weather-resistant construction for use in harsh environments helps ensure reliability and
  dependability.
  
• Incredibly minimal focus breathing.
  
• Air Sphere Coating (ASC) helps significantly reduce lens ghosting and flare.
  
• This lens features 2 UD elements to minimize chromatic abberration, and 2 aspheric lenses for incredible
  quality from edge-to-edge.
  
• Comes with attachable rear filter holder.
