Canon RF 70-200mm F2.8 L IS USM Z Telephoto Zoom Mirrorless Lens (Black) 6593C002

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.
