Newbie needs math check, new pocket cam.

Kowa makes a decent 8mm non fisheye lens that looks to give about 24mm FF equivalent with the 3x s16 crop. 

Seems like the best solution so far./

A crop out of the center of a fisheye will still have heavy distortion. Check youtube or vimeo for examples.

Agreed, and even non fisheyes will have distortion. I notice slight distortion (enough so that I won't use unless it's a wide shot) with my Rokinon 16mm on a BMCC.

Here's the Kowa in action. I can't see too much distortion. The bokeh is a bit weird though.

I see a lot of distortion. Very wide lenses shouldn't use shallow DoF. If not extremely cropped, the focal plane is curved too much (three flowers on the window sill, either the one in the middle or the others appear sharp). Isn't there an 8mm Kowa?

wait, I thought this was the 8mm Kowa????

 

EDIT: oh my bad. I linked to that video via a 8mm Kowa thread, turns out, you're right, it's the 6mm.
