The RF 24-105mm f/2.8 L IS USM Z Lens from Canon is the first of its kind at this focal length and aperture with a powerful multiuse zoom for photo and video. The constant f/2.8 aperture allows for optimal low light performance and provides flattering bokeh for portraits at any focal length. In-lens optical image stabilization offers five and a half stops of correction, or eight stops with Coordinated IS when paired with a compatible camera. Four ultra-low dispersion elements and three aspherical elements help create sharper images and reduce chromatic and spherical aberrations. By utilizing dual Nano USM motors, this lens achieves fast and nearly silent autofocusing. Additionally, the RF 24-105mm f/2.8 benefits from Super Spectra, Air Sphere, and Fluorine coatings, which work together to minimize ghosting and flare caused by lens surface reflection. While many comparable lenses are capped at 70mm, this lens's ability to push to 105mm gives users the advantage of stronger portrait focal lengths.
