This mic is sold in kits, and the one I used was the Q DSLR-Video Kit. It comes with everything a DSLR shooter needs (the mic, shock mount, shoe mount, output cable, wind protection, batteries and case). I really liked its size and sound. The mic itself is the same size and weight as a metal ballpoint pen. It has an impressively clear and present sound for such a compact shotgun. The output of this mic is a small, threaded connector, and it requires a special cable that screws into the thread. The other end of the special cable has another thread onto which you must attach a special output connector. Because there are so many proprietary parts, its best to purchase this mic in one of the kits. B&H sells just the QMSG1 mini shotgun on its own, but without all of the supporting accessories, its useless. This mic requires two button-sized batteries to operate. I believe theyre hearing aid batteries, so, in theory, you can easily pick them up at a local pharmacy. As much as I love the small size of this microphone, the included carrying case is impractically large. The included outdoor windscreen is a little too heavy for the mounting hardware to handle. The weight of the windscreen makes the mic swing away loosely from where you position it. But, as you can hear in the shootout video, this mic sounds really good. The sensitivity of this microphone and the sensitivity of the input on the GH2 are a match made in video nerd heaven.
