I bought this microphone recently and used it myself to record on both my K3 and D800. I'm much happier with the stabilized video of the K3 by the way. The Rode is brilliant, I can't believe how good this microphone sounds, especially for bands. I plan to use it a lot more.
only complaint, for $250 it should include a carrying pouch. The pouch is an extra $25, but still... it should be included. I will probably buy the think-tank media bag that attaches to the Digital Holster 20 I own (which I love by the way).
changing audio levels on the fly is a breeze, especially with the on screen meter. now I just wish it had focus tracking in video mode
