Canon RF 24-105mm Zoom Lens The RF 24-105mm f/4L IS USM is a premium walkaround lens from Canon’s new line of RF lenses within their EOS R full-frame mirrorless system. Characterized by its exceptional focal range and fixed maximum aperture of f/4, this highly versatile piece of glass is great for capturing more of a scene at the widest focal length, zooming in on faraway objects from a distance at the longest focal length, and covering a variety of shooting scenarios in between. Its nine rounded aperture blades are also designed to produce pleasing circular and velvety smooth bokeh. Shooting sharper images, even in low-light conditions, is made easier with up to five stops of image stabilization. The new and configurable Control Ring can be used to intuitively adjust different exposure settings, including the aperture, ISO, and exposure compensation. The lens also utilizes a ring-type NANO USM autofocus motor for achieving fast and accurate yet smooth and noiseless focusing in both photo and video modes. The RF 24/105mm f/4L IS USM features the L-series dust, moisture, and weather-resistant lens body, and is specifically designed for use with Canon’s full-frame EOS R mirrorless camera.
