The 7.5mm Samyang on the M4/3 is equal to a 15mm 180 degree diagonal fisheye on the M4/3 cameras. You'll need 6 around + zenith and nadir with the 7.5mm Samyang.
When the 7.5mm Samyang is adapted to the NEX, then it becomes a cropped circle fisheye and you can do 4 around + nadir.
I don't know of any full circle fisheye for the M4/3 systems.
