Don't really understand this lens! For the same money you could buy a full frame camera and an 85mm f 1.4 or 1.8 which would give you much better IQ and the same or better bokeh. Also it wouldn't be that much heavier or bulkier!
In general the ultra fast options don't seem to make much sense on m43 or APSC; they are expensive and not as good as the FF equivalents. The smaller formats excel at small lenses which are only moderately fast - and the price you pay (well worth it when you are travelling!) is some limitation on how narrow your DOF can be (even the lovely Olympus 45mm 1.8 only has the bokeh of a classic 85mm f3.5 on FF!). So far it seems that if you really want narrow DOF you are better off having an FF set up (as well?) rather than going for an exotic sub f1.0 lens..
