Sony A65 has a Sony/Minolta Alpha lens mount and currently there are 139 native lenses available for this mount.
A65 also has a sensor based image stabilization system which means that all of these lenses will be stabilized when used on A65.
Since Sony A65 has a APS-C sensor, it has a focal length multiplier of 1.5× 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 A65.
