Sony A77 has a Sony/Minolta Alpha lens mount and currently there are 143 native lenses available for this mount.
The latest released lenses that are compatible with the A77 are the Tamron AF 28-80mm f3.5-5.6, the Tamron 17-50mm f2.8 XR II LD and the Tamron AF 28-75mm f2.8 XR LD.
A77 also has a sensor based image stabilization system which means that all of these lenses will be stabilized when used on the A77.
Since Sony A77 has a APS-C sensor, it has a focal length multiplier of 1.5x 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 A77.
