I've used the 8mm/2.8 to do immersive panoramas. Theoretically, you can use
only 2 images, but it's not easy, especially since the Zuiko only has a 179
deg FOV. But unless you use expensive IPIX tools, they're aren't any legal
tools to stitch 2 fisheye images together. (Panorama Tools will do it, but
you have to get the version from outside of the EU.)
Practically, you need at least 3 images. Plus a zeinith and nadir (pointed
straight down) to get good stitching at these two axes.
If anyone's interested, there is a link page on my website to several
resources using the Panorama Tools toolset.
I use the 16mm Zuiko, which takes 5-6 horizontal images, plus two for the
up/down areas and stitch it together with Panorama Tools. There are a few
test panos on my website, but I'm currently working on revamping them.
These were taken with the 8mm/2.8.

Immersive panoramas... AKA 'virtual reality' pictures. With a fisheye you
can do it in about 3-4 images, so there is less stitching to do. One web
page I studied trying to learn about this used a full-frame fisheye and did
it in about 5 pictures, but the 180 degree coverage in theory would only
require two, in practice you'd probably want three to get about 60 degrees
overlap at the edges. I have this vision of laying on my back in the tall
trees grove at Redwood National Park and shooting the sunlight filtering
through 360+ foot tall redwoods...
