Inon 165 fisheye AD bad on S110, why o why?

[mkhilario]

Results with my old Inon 165 AD fisheye are pretty awful with my S110 in a Nauticam housing (zoomed in to 35mm equiv.). Why is that? I was considering the Fix UWL-28; I've seen some decent sample photos with S100/110 (zoomed in to 28mm). Why does the Fix work and the Inon 165 not?

So I continue to soldier on with my Nauticam Wet Mate dome which gives corner to corner sharpness but only 80-ish degrees of coverage..

Because the UFL165 is for 35mm equivalent
Best lens for the S95/100/110/120 is the Fix/Idas UWL-04

I don't understand if the camera zoom is set at 35mm equivalent, why doesn't it work well?

Because the lens is too far from the port. The S95 an 28mm camera was the last one to work decently, you can try of course but with that amount of zoom and distance the field of view will be more 130 max

Any recommendations for best aperture settings to maintain corner sharpness? I'm talking general CFWA reef scapes, no sun balls.

Cfwa requires small apertures anyway but for landscapes f/4 works well. I think you can push even wider but never had to
