Canon RF Mount. The Canon RF 24-50mm f/4.5-6.3 IS STM belongs to Canon’s line of RF-mount lenses. It’s compatible with Canon RF cameras. It does not work with Canon EF-mount cameras.

Wide-to-Normal Zoom. This lens’s versatile wide-angle to normal-length zoom range makes it ideal for landscapes, cityscapes, street scenes, portraiture, and product photography, among other applications. Its variable f/4.5-6.3 aperture isn’t going to give you much flexibility in very low light, so it’s probably not the best for night shoots. Using an APS-C camera? You’ll get a 38-80mm equivalent focal length.

Advanced Optical Design. This lens’s eight-group/eight-element optical formula includes two aspherical elements that work to minimize chromatic aberrations and color fringing while providing high clarity, color fidelity, and sharpness. Canon has applied a Super Spectra coating to the lens elements to further combat ghosting and flaring, even in harsh lighting.

Built-In Autofocus. This lens uses a screw-type Stepping Motor to provide fast, accurate, and nearly silent autofocus performance for both still and video shooters. You also get full-time manual-focus override for precision adjustments. This lens lets you work with a 0.11x maximum magnification ratio and a 11.8-inch minimum focusing distance so you can get reasonably close to your subjects.

Optical Image Stabilization. The 24-50mm f/4.5-6.3’s built-in image stabilizer compensates for 4.5 stops of camera shake on its own, or 7 stops if you’re using an EOS R-series camera with an In-Body Image Stabilizer (IBIS), so that you can shoot in lower light and at slower shutter speeds without worry.

Configurable Control Ring. This RF mount lens features a new integrated, configurable control ring that you can use to adjust a range of exposure settings, including ISO, aperture, and exposure compensation.
