I have checked and this lens also works perfectly on my Sanyo PLC-XM100 : )
According to a quick web search, this lens was previously badged as the Sanyo LNS-S20 before Panasonic bought Sanyo and the lens is compatible with the following:
Panasonic PT-EW730ZE, PT-EZ770, PT-EZ580, PT-EW730, PT-EW640, PT-EX800, PT-EX610, PT-EW540, and PT-EX510
