The RF85mm F1.4 L VCM is an entirely different L-series lens, targeting a wide range of still image and video shooters, with a combination of medium telephoto coverage, a fast f/1.4 maximum aperture, and excellent optical design. On a full frame camera this lens gives you one of the most common focal legnths for portraits, which has been used for decades. 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. And finally, focus breathing is barely noticeable on this incredibly versatile lens.
