• New 24mm L-Series hybrid lens featuring an iris ring for manual iris control.
• Nano USM is used for floating focus and a Voice Coil Motor (VCM) for rear focus - great for video.
• L-Series level durability and weather-resistant construction for use in harsh environments helps ensure reliability and dependability.
• Incredibly minimal focus breathing - within 2.5% of the entire range in the lens alone! Further electronic breathing correction brings it to within 1.0% of the entire range.

Details: 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.
