Prospective difference!

its the one and only time 25mm does not equal 50mm in conversion.  If you use 50 mm on both cameras from the same distance and crop the full frame to match fov of m4/3 then the blur should be the same. (That is as long as they are stopped down f1.4 m4/3 and f2.8 for ff.  This does make things really difficult.
