The subject innovation provides for systems and methods to facilitate obtaining an overall well focused catadioptric image by combining portions of multifocal images in a fast and reliable manner. The resulting images benefit applications where high image resolutions are desirable over a large field of view. In an aspect, shallow depth of field imaging with respect to the caustic volume boundary can be correlated to annular shaped best focal regions for multifocal image sets. These annular regions are generally independent of scene composition and generally dependant on optical system parameters allowing fast computation of overall well focused output images comprising concentric best focused annulus areas from a multifocal image set.
