The rf 100-300mm f 2.8L is usm is the first of its kind, delivering a constant f 2.8 Aperture in a super-telephoto zoom. Its sophisticated optical design featuring one fluorite, four ud ultra-low dispersion , and one gmo aspherical element ensures surgical sharpness that rivals the best primes. The internal zoom and focus mechanism means the lens length never changes, maintaining a consistent center of gravity that is ideal for use on gimbals, monopods, or handheld shooting.Equipped with a dual nano usm system, the lens drives two separate focusing groups independently for virtually instantaneous and silent autofocus. Handheld stability is guaranteed by the 5.5-Stop optical image stabilizer, which can reach 6.0 Stops when paired with an eos r camera featuring ibis. Built for the most demanding professional environments, it features l-series weather sealing, a heat-shielding white coating, and a dedicated focus preset button alongside four customizable l-fn buttons. For ultimate reach, it is fully compatible with rf 1.4X and 2x extenders, transforming into a high-performance 200-600mm f 5.6 System.
