The Canon RF 20mm f/1.4 L VCM Lens is an entirely different L-series lens, targeting a wide range of still-image and video shooters, with a combination of strong wide-angle coverage, a fast f/1.4 maximum aperture, and excellent optical design. On a full frame camera this lens gives you a vivid wide-angle look which has for decades been used in landscape, street photography, architectural photography, and strong commercial imagery.  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 on the floating focus unit for incredibly fast autofocus.  And finally, focus breathing is barely noticeable on this incredibly versatile lens.
