    Actually, you lose a lot adapting it to micro 4/3. You can't just take a fisheye designed for a larger sensor and adapt it on like you would a rectilinear lens. Since the outside of the image is much more compressed, you waste your money by buying this for micro 4/3. Micro 4/3 cameras need the 7.5mm or you won't get the fisheye effect.

    Wonder how it would perform with a focal reducer? I've seen a handful of Samyang/Rokinon 8mm fisheyes adapted with focal reducers and they seem to work well. I wouldn't buy the Opteka and a focal reducer just for a fisheye, would be a lot less expensive to just buy the m4/3 Samyang/Rokinon 7.5mm....
