9-18mm lens Vs. 8mm Fish Eye , my 2psi

[Storker]

The 9-18mm is not very sharp and nowhere near as sharp as the 8mm lens.

You might like to try adding a +2 closeup lens ("diopter") to the 9-18 before dismissing it completely. It makes a very noticeable difference. I'm always shooting with a +2 screwed onto my 9-18, and I'm a lot happier with the IQ now.

I don't understand what's wrong with the Oly 9-18, I use it all the time @f/4-5.6, but then again in the Nauticam 4"mini dome, which doubles for the 60mm Macro as well.
Yes I am also waiting for the pro 7-14 from Oly but it will definitely require a LARGER dome. JM2c

On a tangent, which are the ports the 60mm macro fits in?

Nauticam 4" Wide Angle Port Nauticam part # 36137 Want to shoot macro with your wide angle port? It is now possible and easy with the Nauticam M67 Flip Diopter Holder for 4” Wide Angle Port
then there is the dedicated Nauticam Olympus 60mm macro port #36163

perhaps others as well from Zen not sure which though

Well, frankly, the corner sharpness behind the 4" semidome is crap unless you add a +2 diopter inside the dome. With the diopter it's rather nice, though.

It's my standard UW lens (I'm a WA/CFWA rather than a macro guy, and I haven't been able to afford the 8mm FE yet), but I wasn't satisfied with it before I started to use a dry diopter on it. Even at f/8-f/11, the corners were rather mushy.
