Pentax Q10 has a Pentax Q lens mount and currently there are 8 native lenses available for this mount.
The latest released lenses that are compatible with the Q10 are the Pentax 08 Wide Zoom, the Pentax 07 Mount Shield Lens and the Pentax 06 Telephoto 15-45mm.
Q10 also has a sensor based image stabilization system which means that all of these lenses will be stabilized when used on the Q10.
Since Pentax Q10 has a Small Sensor sensor, it has a focal length multiplier of 5.53× 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 Q10.
