Canon R7 has a Canon RF lens mount and currently there are 43 native lenses available for this mount.
The latest released lenses that are compatible with the R7 are the Canon RF-S 10-18mm F4.5-6.3, the Canon RF 24-105mm F2.8 L and the Canon RF 200-800mm.
R7 also has a sensor based image stabilization system that is up to 7.0-stops effective which means that all of these lenses will be stabilized when used on the R7.
Since Canon R7 has a APS-C sensor, it has a focal length multiplier of 1.6x so you have to multiply lenses original focal length with this multiplier to find the Full Frame equivalent focal length of the lens when mounted on R7.
