I have a couple of questions.
Will the circular ring go away underwater? My LX5 did the same thing on land but I never got around to using the H100 underwater with it.
To me it's hard to tell if the edges are very soft or if they are only out of focus, probably a both. I may try shoot some photos on a flat wall and stop it down a bit more to see how it goes.
At least the combination appears to work.
12mm-50mm @ 12mm F5.6 1/640
12-50 @ 12mm w/H100 28M67 Type 2 F5.6 1/640
as above but cropped
