Overview

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.

Incredible Feature Set From an Incredible Lens Series
This lens has a lot going for it. You already know about the VCM and Iris control ring, but there is so much more. You can attach filters to this lens in two ways, a front 67mm screw thread allows for screw-on filters, and in the back of the lens is a cut gel filter holder (bundled). You also have a control ring and a control button both of which you can assign functions to. This lens is also dust and weather resistant, has two aspheric lenses, and ASC (Air Sphere Coating), SSC (Super Spectra Coating), and Fluorine Coating to significantly reduce ghosting and flare.
