The latest released lenses that are compatible with the 77D are the Carl Zeiss Makro-Planar T2/50, the Tokina 35mm f2.8 Macro DX and the Canon 50mm f2.5 Macro.
Canon 77D doesn't have a sensor based image stabilization system but 113 of these lenses already comes with optical image stabilization.
Since Canon 77D has a APS-C sensor, it has a focal length multiplier of 1.6× 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 77D.
