Is Sigma 17-50 f2.8 sharp enough for GH4 ?

Panasonic GH4 for shooting video is gonna be my new my camera very soon. I'm wondering what I should do about the lenses...
Should I buy a new one like Olympus 12-40mm 2.8 or buy a Metabones and use my Sigma 17-50 f2.8 with IS?
I've been watching at some videos in youtube/vimeo and I really have the feeling that Sigma is not sharp/quality enough... am I right? It must be the compression used to uploaded? Any opinions about that?

I would test if possible because there is no guarantee that the IS is going to work well when used with a lens adapter. I originally bought my Panasonic 12-35mm f/2.8 lens because of the built-in OIS, which works really well with my GH4 camera. ( after applying all the firmware upgrades, new lenses should already have these updates applied to them )

As far as sharpness goes, I find the Micro 4/3 lenses to be too sharp sometimes, and the adapted lenses like the Tamron 17-50mm f/2.8 to have just the right amount of sharpness for what I want. ( though they can be soft in the corners of the frame when compared to the Olympus or Panasonic Micro 4/3 lenses )
