The RF50mm 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 image quality. On a full frame camera this lens gives you a Standard-angle look which has for decades been the most "all-purpose" focal length for photos and videos. On the video side, this lens really shines with a dedicated manual Iris ring, and a  linear focus motor called a VCM (Voice Coil Motor) that is virtually silent.  The VCM works in tandem with a Nano USM (Ultrasonic Motor)  on the floating focus unit for incredibly fast autofocus.  And finally, focus breathing is barely noticeable on this incredibly versatile lens, minimizing distractions for your viewer, and keeping your imagery and story as the priority.
