it's not

50 f/1.4 equivalent. it's not. it's probably more like 50 f/2.8 equivalent.
I wish I could use my canon 85/1.2 in a crop body and think of it as a 135/1.2 equivalent.

Your comment makes no sense.  An f1.4 lens is f1.4 regardless of crop factor, in terms of the brightness. It will have a depth of field like an f2.8 lens on full-frame.

Either way the same rule would apply to your 85mm f1.2.  It'd be like a 170mm on micro 4/3, f1.2 brightness and depth of field like an f2.8

Olympus have announced a 75mm f1.8 for m43, coming later in the year. Will be much smaller than the Canon of course.
