The RF35mm F1.4 L VCM 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.
