Sigma Quattro has a Sigma SA Bayonet lens mount and currently there are 77 native lenses available for this mount.
The latest released lenses that are compatible with the Quattro are the Sigma 12-24mm F4.5-5.6 EX DG HSM, the Sigma 20mm F1.8 EX DG RF and the Sigma 24mm F1.8 EX DG.
Sigma Quattro doesn't have a sensor based image stabilization system but
29 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.
