Does not have to be that long. Look at the Pana 42.5 1.2.

This is something easily done on FF lenses either the Canon 85mm 1.8 or Nikon 85mm 1.8G.  On FF camera's these lenses are absolutely perfectly balanced and manageable.  Both optically good.  The equivalent DOF of the 42.5 is 2.4, and by f2.4 both Canon and Nikon are tack sharp, so it sets a high bar for MFT lenses to follow wide open.

I've also tried the 45mm 1.8...great lens and usually better than 50mm's are for APS-C, but again at f 3.6, its very easy for Canon and Nikon to be sharp edge to edge and stellar stopped down.  I've been through many copies of the 45 and they had slight centering issues.
