Well, there is a piece of information missing for this judgement:
The MTF-chart does not tell for which aperture it applies. (At least
I dont see that anywhere).
But on the other side ... this is a crop-2.7-system ... I guess it
is diffraction-limited for every aperture beyond f/5.6 ... so,
very likely the MTFs are for wide open aperture.

I guess since the aperture is not given, it is the widest used in the tests... And these are 60lp/mm by the way... Still not so impressive but I don't think before f/11 the diffraction will have an impact on that 3,40 microns of pixel size.
All in all, I think the lens line is very poor in terms of "fastness"... One could expect faster primes and smaller zooms. That 10-100mm looks huge on the V1 and it's hard to understand why... I assume the register distance is shorther than m4/3 and Sony E mount. And with regard to that, "in theory" a variety of lenses can be alternatives to those...
