Sigma Quattro has a Sigma SA Bayonet lens mount and currently there are 76 native lenses available for this mount.
Sigma Quattro doesn't have a sensor based image stabilization system but 23 of these lenses already comes with optical image stabilization.
Since Sigma Quattro 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 Quattro.
