Sometimes I feel that Olympus made their mistakes in the first place when they chose the 43-size sensor. The m43 system does not seem to have much size/weight advantage compared to an APS mirrorless system, e.g. EM5+PL 25/1.4 vs XE1+X35/1.4. To compensate the limit of the very small sensor they have to make "over qualified" (in some sense) lenses, e.g. the old 43 pro lenses. Look also at the f0.95 Voigtlander lenses, the f1.2 PL 42.5mm lens. They are all quite bulky/weighty but have only mildly fast apertures f1.9-2.4 in terms of dof.
