Currently there are 3 native Macro Prime lenses for Canon R7 and 2 of these lenses are autofocus (AF) type.
R7 also has a sensor based image stabilization system which means that all of these lenses will be stabilized when used on R7.
Since Canon R7 has environmental sealings (Weather Sealing), you may like to couple your camera with one of these 1 Macro Prime lenses with Weather Sealings.
