Panasonic 8mm fish eye or samyang 8mm?

Hi guys, was wondering if any of you folks used both before and what's the outcome.

I've read quite a few reviews on the net but nothing beats a truthful comment.

This is to fit into my Olympus housing for omd m5 with zenunderwater 4" dome.

Cheers

That would be interesting, I think many have one or the other only.

I have Panasonic, E-M5 and Nauticam housing and dome. I like to have the option of auto focus. That said, most of the time I have had this lens (soon a yr) I have actually locked the focus as the low-light levels makes the AF hunt anyway.

In that respect, maybe the Samyang would work ok, however I think one would need a focus gear, because the focus needs to be set underwater and I think it is going to need to be very precisely set. Is there any obstacles for producing a 3D printed gear for that manual lens?
