Along with the first Canon RF mount macro lens, Canon introduced two telephoto lenses of the same system. These are the Canon RF 400mm F2.8 L IS USM and RF 600mm F4 L IS USM models.
The lenses are equipped with image stabilization systems that achieve 5.5 stops of exposure, regardless of which camera the lens is used with. The stabilizer has three modes of operation: one is more suitable for shooting stationary objects, the second is for panning, that is, shooting with wiring, and the third is for shooting lenses that move unpredictably. The optical designs of these lenses are equivalent to those of similar Canon EF mount lenses. According to
According to the manufacturer, the new telephoto lenses are ideal for shooting sports events, airplanes, trains, cars and wildlife such as birdwatching.

For added convenience, two focusing positions can be saved with the ability to instantly return to any of them.
