      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.

      >> PTGui calculates the 16mm + fisheye converter for NEX to be about 15-16mm.  I shoot 6 around plus zenith and nadir patch.  It's an ok combination but not professional quality.

      >> The Samyang 7.5mm on a M4/3 is about 15mm so expect the same.  The Samyang on a NEX gives complete sphere with 4 around and is very good.
