Just wanted to put in my findings. I've owned the 8mm fish eye lens and used it with my epl5 setup for a year and loved it. However it had its limitations, mainly not being able to zoom. When in Palau it was near impossible to get shots of sharks. I did get amazing pics of manta (fit in the frame easy).
This Year, I upgraded to the E-m1 setup. I also decided to get the zen 170mm port and 9-18mm lends. I do own the 12-40mm pro lens but didn't opt for the gear so i've yet to try it. Overall I find the $1600 investment (port and lens) kind of a waste. The 9-18mm is not very sharp and nowhere near as sharp as the 8mm lens. I'll be selling the lens and hoping the new 7-14mm lens will fit the 170mm port.
I've switched to only the 8mm lens for wide shots. and 60mm for macro.
Here are some pics with the 8mm taken the other day:
