Did anyone watch the HD video? Any comments about the video or audio?

I did

I'm looking for a good/non expensive mic now

The "dead kitten" shouldn't cause more than a few dB of attenuation to high frequencies and even less impact on mid- and low frequencies.

As for the low levels, make sure the -10 dB pad on the mic is turned off. Also, check to see if the K-7 provides different internal gain options. I'm not familiar with the K-7's mic input options, but often digital audio and video recorders have high and low gain options. Try high, if it exists.

I haven't yet found the mic sensitivity specs for the Rode mic, but a more sensitive mic would help with levels, too, but probably not enough to make a huge difference.

Finally, you may need a preamp between the mic and K-7 to get strong enough levels, depending on the results of the above.

OK, thanks!

I've just had a look and there don't seem to be any gain options in the camera.

-38 dB re 1V/Pa (12.6 mV @ 94 dB SPL) +/- 2 dB @ 1 /KHz

Possibly, but if you check the video, the conditions were actually very quiet. I was surprised the levels were low but they were probably quite accurate, and I have no complaints about the quality of the sound or stereo image.

I need to try it in a greater variety of situations.

That's reasonably sensitive. I doubt you'll find another mic offering higher sensitivity sufficient to raise your levels significantly.
