This is Canon's first RF lens designed for macro image capture with a magnification of 1.4x and autofocus. Featuring a fixed 100mm focal length, a fast F2.8 maximum aperture for blurred backgrounds and low light shooting, fast, highly-precise AF, and an SA (spherical aberration) Control Ring, the RF100mm F2.8 L MACRO IS USM lens gives you the option of creating dreamlike or romantic images with a soft-focus look.

Additionally, the Optical Image Stabilizer supports up to 5 stops of shake correction while the Hybrid IS compensates for angular and shift camera shake during macro shooting. When paired with an EOS R camera with in-body image stabilization, the Canon shooter can expect up to 8 stops of shake correction. The lens features a high speed and smooth autofocus with Dual Nano USM. 

The RF 100mm F2.8 L Macro IS USM is priced at $1,399 and is expected to ship in July 2021.

The Canon RF400mm F2.8L IS USM is designed to be optically identical to the EF counterpart. Optically, it has a 9 blade circular aperture that provides users beautiful bokeh and ideally blurred backgrounds when the aperture is stopped down. It has an optical image stabilization system with up to 5.5 stops of shake correction, including three IS operation modes. 

The lens is also compatible with Canon RF 1.4x and 2x extenders and features a customizable electronic focus ring with manual focus capability during Servo AF. Additionally, the lens features Canon's L-series dust- and water-resistant design with vibration and shock resistance. The front element has a fluorine coating for easy cleaning.

Essentially what you're getting here is the EF 400mm f/2.8L IS III in an RF mount, which will be nice to have for the newer EOS R system or when shooting with the Canon C70 or RED Komodo

The RF 400mm F2.8 L IS USM Lens is priced at $11,999 and is expected to ship in July 2021.

Similar to the RF 400mm, the RF 600mm is optically designed for the EF version. The lens weighs 6.81 lbs with a minimum focusing distance of 13.8 feet, respectively. It shares the same 9 blade aperture design, 5.5 stops of camera shake correction, extender compatibility, and dust- and water-resistant design as the RF 400mm telephoto lens. 

Both the RF400 and the RF 600mm feature a customizable electronic manual focus ring on the lens barrel where you can select from three different speed levels to adjust manual focus to your desired preference. They also have two focus presets to instantly return to one or two memorized focus distances. 

The RF 600mm F4 L IS USM Lens is priced at $12,999 and is expected to ship in July 2021.
