The Canon RF 24-105mm f/2.8L IS USM Z Lens is a versatile zoom lens for both photos and videos. It's the first lens of its kind with a 24-105mm focal length and f/2.8 aperture. It has dual Nano USM motors for fast and quiet autofocusing. The constant f/2.8 aperture allows for great low-light performance and nice background blur in portraits. The lens has in-lens optical image stabilization for steady shots, with up to five and a half stops of correction (or eight stops with Coordinated IS when used with a compatible camera). It also has special elements and coatings to reduce image distortion and unwanted reflections.
