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?

I haven't tried in such a small dome I have used the 7-14 a little in the 170mm Zen dome and it does OK at 7mm but corners are a little soft.  I think though that using a 14mm full frame equivalent lens in a 100mm dome would be stretching the friendship quite a bit particularly as the 7-14mm doesn't focus ultra close.  I recall seeing people complaining about the image quality in the Nauticam 6"dome back in the past on Wetpixel. 

I would be cautious about relying on written advice that lens xyz is fine behind dome abc unless there are sample pics to go with the post, people's definition of fine varies from "sharp at 100% in the far corner" to "I shot a shark and I can tell it's a shark and got lots of likes on my post"
