Hi everyone. I have the Hosa XVM-101F cable and Audio-Technica AT875R shotgun mic. Very good combo for the GH2 in which the port powers the mic. Just got my GH4 yesterday. This combo seems to be working, I'm getting good levels with Mic Level Limiter set to off. I'll do more testing but I have the Mic Level Adj set to +2dB.....so far so good! I had read this combo didn't work so well on the GH3 (never did buy one). Might be an alternative to the Videomic Pro.
