Thanks to member Captura for revealing that certain Panasonic conversion lenses fit right onto the Sigma 30 and Sigma 19. Two ultra-wide Lumix UW conversion lenses (CWC1 and LW46, both x 0.75) screw right onto the 46mm threads of either Sigma lens. I have the LW46, which was actually the predecessor of the CWC1. Price was about $125 like new used through Amazon.
