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.FeaturesIncredible Feature Set From an Incredible Lens SeriesThis lens has a lot going for it.
