I have recently acquired an Inon Bug Eye Lens courtesy of Ryan Canon. Using this lens in Alor and Komodo i had a lot of frustration, and quite a bit of pleasure.
Using the custom made Nauticam 60mm port i was able to get some useable images, i actually used the lens in autofocus quite frequently, which was probably a bad idea!
In manual focus mode the Nauticam 180 degree viewfinder was fantastic, and the field of view from this micro fisheye lens is amazing, if not a little unsharp at the corners!
