Non-shotgun cardioid condenser?
After looking into the suggested links and reading about things a bit, I'm leaning toward getting her a non-shotgun cardioid condenser mic that can be mounted on top of the JVC GZ-HD7. My reasons for this are as follows. I appreciate any comments about whether this is good or bad thinking.
1. She will be filming both indoors and outdoors. It seems to me that it would be better to have a cardioid condenser mic for outdoor filming (and pick up the extra noise) than to have a shotgun mic for indoor filming and get that "roomy" sound.
2. We don't have the money for more than one $250 microphone at the moment, but if she continues with the film thing, we will eventually. In the meantime, I'd rather buy one good microphone than two crappy ones.
3. She will be experimenting a lot this summer with filming different locations, etc, and most of this she'll do by herself. It won't be feasible for her to get a boom pole and someone to help her. (In other words, she's not there yet.) Hence getting something that can be camera-mounted.
4. If, at a later date, she wants to expand her collection, we can get a boom pole, shotgun mic, etc.
Again, I appreciate any advice, even if it's to say that I'm a total idiot and thinking about things completely wrong. Thanks a lot for all of the help so far.
