Actually, one of my projects in college was to design a complete surround methodology. Since we figured the widest stereo speaker spacing a human could tolerate and still get a decent location placement at all points in-between was about 60 degrees, we settled on a duodecahedron arrangement of mics. That's 12 hypercardiod mics, each located on a sphere. As such, each mic was 60 degrees away from any other mic. Never built the thing, though.
So the innovative, if an "expected" evolution of camera-audio, is the bringing together of a semi-hyper cardioid mic, just visible through the mini-blimp & "cage" PLUS a solid state recording module. I suppose that was inevitable.
However, I want to experience an improvement in the handling noise creeping into the business-end of the receptor. I have three Rode on-camera mics and need to be very aware of the isolation. Not so with my comparable Senni kit.
An interesting and potentially situ adaptable piece of kit. It looks like it could also be hand held?
Reliving bad memories of fixing up my old Tascam 424 Portastudio with a shoulder strap and a 12V lead acid battery with a shotgun mic in my left hand AND carrying my full size VHS camcorder on my right shoulder to record an important interview with the mayor and a city councilman.
