#RF400mm f/2.8L IS USM

Along with the EOS R3 announcement, Canon has launched its three brand new RF lenses, the RF100mm f/2.8L IS USM, RF400mm f/2.8L IS USM; RF600mm f/4L IS USM. According to Canon, the RF100mm f/2.8L IS USM is the world's first, medium telephoto macro lens with a maximum shooting magnification of 1.4x. The RF400mm f/2.8L IS USM and RF600mm f/4L IS USM super telephoto lenses are native to the RF mount, which provide professional and advanced amateurs with extra reach that comes with a high level of image quality, reliability, and durability. RF lenses have the rear element of the lens closer to the image sensor, which allows a new floating method that enables the RF100mm f/2.8L IS USM to have a maximum shooting magnification of 1.4x. The RF100mm f/2.8L IS USM is equipped with a spherical aberration (SA) control ring, that allows users the ability to toggle between soft or hard depictions of bokeh by turning the SA control ring. The RF100mm f/2.8L IS USM features an improved optical IS when compared to the 4-stop IS capability of its EF equivalent lens, the EF 100mm f/2.8L Macro IS USM.
