When I bought it cost GH4R 15000 and 12000 GH4, today the pricing a little different and probably would have thought a couple of rounds whether GH4R is worth the money or not. In particular, if you do not work professionally and not in absolute need of a longer recording time.
I think certainly that the V-Log is the top - even if you only play out internally (when you absolutely need more headroom in the highlights), but that can be purchased GH4-ball for relatively small money.
Have had the camera for almost a year now, before that, I worked a lot with GH4 at another company, and before that with the GH3. It is hard to imagine a better camera for video. The only thing I miss is that case ND filter, and some sort of breakout solution for SDI and XLR. Then the camera would have been the only option for 30 000 of my book.
