Redesigned for professionals who require quality and consistency in both photo and video applications, the Canon RF 70-200mm f/2.8 L IS USM Z Lens is an internally focusing, internally zooming telephoto workhorse that harnesses the power of the brand's latest mirrorless cameras. Its hybridized construction is optimized to produce professional results whether hand-wielded on the sideline or balanced atop a gimbal. The lens's internally focusing, internally zooming construction optimizes it for video shooters who intend to mount it on a gimbal. Two floating focus Nano USM motors drive the Dual Pixel CMOS autofocus and can operate independently of one another, resulting in fast and quiet autofocus that also benefits video. The construction also suppresses focus breathing, maintaining the integrity of the image as you move through the zoom range, and a manual, lockable iris ring ensures the integrity of the exposure as you shoot. Optically, the lens has 18 elements in 15 groups, incorporating two super ultralow dispersion elements, another ultralow dispersion element to minimize chromatic aberrations, and three additional aspherical lenses to ensure the highest edge-to-edge image quality. Canon's own Air Sphere and Super Spectra Coatings are applied to the front element to reduce ghosting and flare, while a fluorine coating repels oil and water to protect the lens.
