The RF24mm F1.4 L VCM is part of the expanding Hybrid lens series, targeting a wide range of still-image and video shooters, with a combination of wide-angle coverage, a fast f/1.4 maximum aperture, and excellent optical design. On a full frame camera this lens gives you a wide-angle look which has for decades been used to add drama to photos and videos, and has always been a very popular for establishing shots.  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.

• Canon RF mount: Compatible with all Canon EOS R-Series Cameras with the Canon RF Mount.
• Wide-angle lens for broad composition: Delivers stunning perspectives and allows you to include more of the scene in the frame.
• 24mm focal length: Excellent for capturing dramatic landscapes, cityscapes and other wide shots.
• f/1.4 maximum aperture: Wide-open aperture performs exceptionally well in low-light settings. Provides remarkable depth-of-field control, so you can softly blur the background and draw attention to your subject.
• Incredible Feature Set From an Incredible Lens Series: This lens has a lot going for it. You already know about the VCM and Iris control ring, but there is so much more. You can attach filters to this lens in two ways, a front 67mm screw thread allows for screw-on filters, and in the back of the lens is a cut gel filter holder (bundled). You also have a control ring and a control button both of which you can assign functions to.
• Let's focus: The RF24mm F1.4 L VCM is part of a series of “hybrid” lenses that focus on video performance as much as still photography. One of these new features is a change to how the focus system works. There is a Nano USM that controls the floating focus unit, and a VCM (Voice Coil Motor) that powers the rear focus unit. These focus motors work in tandem for incredible speed in near silence.
• Excellent image quality: Again, thanks to the Canon RF lens mount, the RF24mm F1.4 L VCM lens offers great optical quality. Its optical design includes two UD lenses and one aspherical lens as well as Air Sphere Coating (ASC), and Super Spectra Coating (SSC) to reduce ghosting, and Fluorine coating on the front and rear lens surfaces to help mitigate smudges.
• It's showtime: This lens is part of a new family of “hybrid” lenses that focus on video creation as much as still photography. To that end, this lens features a manual iris control ring so you can smoothly change the aperture from f/1.4 to f/16 during video capture.  Thanks to advancements in lens design, focus breathing on this lens is extremely minimal, and backlit images are sharp.  Combine all of these features, and you’ve got a great video lens in your hands.
• Get close: With a minimum focus distance of just 9.4 inches , and an f/1.4 aperture you can capture some really compelling imagery that is unlike anything else.
