I was looking at the Zen WA-100 for the Panasonic 7-14mm to use on an upcoming trip to Cuba and then Fiji. I have the AOI 8" dome already, which works with this lens but it is large to travel with. According to the AOI Pen chart, that dome is the only AOI dome that works. In another thread on Scubaboard the OP posted he had used the 24mm Extension Ring and the DLP-06 4" dome, which is the same combination used for the Olympus 8mm Fisheye, and gotten good results. Has anyone else tried this combination with the Panasonic 7-14mm and what were your results?
