That is a real shame.
On the DC800, why not just zoom in to the equivalent of 35MM native, vignetting should go away, the wet mount lenses were mostly meant to operate with a 35MM equivalent native lens, should be happy and work fine--what am I missing here?
1. 28MM EFOV through a flat port = 52 degrees diagonal
2. 35MM EFOV through a flat port = 42 degrees diagonal
3. Typical .56X (18-20MM EFOV underwater) wet mount lens with native lens set at 35MM equivalent = 80 to 90 degrees diagonal
4. Inon 165AD fisheye with dome (.40X) with 35MM native lens or lens zoomed to 35MM equivalent = 165 degrees diagonal, zoomed to 50MM equivalent it is still around 130 degrees diagonal or more than 3 times as wide as the DC800 alone.
The only wet mount WA lens I know of that is intended for a 28MM equivalent lens without zooming is the Inon 28AD series which of course will not mount to a Sea Life because every camera importer/manufacturer prefers to re-invent the wheel, over and over rather than use superior off the shelf components.
