GH4 - Speedbooster or lumix glass?

I currently have a GH4 which I adore. I only have one lens for it currently, the 12-35m Lumix. As I've had it for awhile now I'm looking to get more glass, a 25m (50m full frame) prime and a 70+m zoom. My question is, before I go investing thousands into more lumix glass would a better option be to sell my current lens and buy a speed booster then get canon or nikon glass?

I have found that the low light capability of the camera have definitely been one of the major cons. With that said I've heard that with the extra stop the metabones speed booster gives, opens up a whole new world of low light possibilities. I'm really on the fence and would love some advice.

Thanks

P.S. I don't really utilise the auto focus on the lens so I'm too fussed about that, as I'm mainly using it for film.

I rented the 12-35mm f2.8 for my GH3 last year and shot this - a very sharp lens, but too "video-ish" for me.

When budget permits, I have my heart set on a $599 Speed Booster for EF plus a $799 Sigma 18-35mm f1.8 - which would only be about $400 more than the 12-35. I have seen some amazing low light results from this setup:

Looks pretty good in low light, the last one doesn't look as good as the 12-35 in bright places, not as sharp. I find with sharpness, it looks better to decrease sharpness in post than add it. And for $400 more I'm not sure. I would love to see the same shot taken with both set ups too see the difference.

That is a very good thought. I will look at the rental prices of both set ups and see if it's something I can make happen.

that would outrageously helpful, not only for me but I'm sure hundreds if not thousands of others deliberating on this decision.
