Hi Phil & Bob,
Thanks for the input - I have looked at the chart on Nauticam's website - but I would like to only buy one port if possible as I travel with my camera and want to keep it lite as possible not to mention the cost. Since I live in MN there isn't any way to 'rent' and try lens so I am trying to find out what ports others have tried with the two lenses.
One port - multiple (wide angle) lenses: Everybody has that wish - but you cannot cheat the physical laws!
I use the 8mm Panasonic fisheye with the 3.5'' port. For me (!) it works perfect. The full pic has benn auto-corrected with Irfan View, the other pic is an unprocessed 100% crop of the lower right corner from the original RAW file (which I cannot attach, so it is jpg with highest quality setting).
