As you know the cheaper mics have a lot of problems - the more expensive mics won't have those issues. Better cables offer better shielding - a better mic offers a better signal to noise ratio. What is "affordable" to you?

You want a good condenser (externally powered) mic with a ?lobar? pick up pattern to put on your boom pole. Lobar pick up means the mic focuses its audio pick up to a narrow area. This is why you want to use a boom pole to get the mic as close the the actor as possible - you?ll get clean dialogue tracks with less ambient noise.

?URL="http://www.sennheiserusa.com/newsite/"?Sennheiser?/URL? is the mic most used by professional sound recordists. They are expensive and worth it. Check out the ME-66 and the ME-67. The MKH60 is the best if you can afford it.

?url="http://www.audio-technica.com/"?Audio-Technica?/url? is cheaper. Check out the AT835B. It?s a workable mic, a little muddy and not as directional as it should be. The AT835ST is a good mic for the price, but it, too, sounds a bit muddy - the vocals don?t sound crisp enough for me.

I?ve never used ?url="http://www.azdencorp.com/"?Azden?/url? mic?s. They?re inexpensive and I don?t hear too many good things about them, but if that's all you can afford it's MUCH better than using the camera mic.

?url="http://www.rodemic.com/?pagename=Home"?Rode?/url? is an inexpensive mic - it?s okay for recording insterments but their shotgun mic?s aren?t very versatile. But once again, if that's all you can afford....

A good mic is an investment. It will last longer than your camera - why skimp? A great place to check prices and purchase is ?url="http://www.bhphotovideo.com/"? B&H Photo?/url?

The further away the mic is from the actors, the higher the volume needs to be. The higher the volume, the more ?noise? you get. Your goal is to have a very high signal to noise ratio - more signal (the dialogue) less noise (the background). Even a very good, expensive Sennheiser mounted on the camera will pick up a lot of background ambiance because it?s far away from the actors.

So you need a boom pole. This can be as simple as a painters pole with a microphone shock mount on it - or a 3 or 4 section, expandable Carbon Fiber, Graphite Fiber or Aluminum boom pole.

This helps me in so many ways, thank you.

I'm thinking I will spend some money on a
good mic. I would mainly be using a mic that
an person could hold in front of an actor
or someone who is speaking like in an
Interview sort of situation, not so much
for catching dialogue in a scene.

well in that case you would probly wanna go with a dynamic mic.
take a look at sm58's they are good mics.

Sennheiser are probably the best. For an older style you could pick up 2nd hand a lot cheaper would be the 416 or 816.
They are still excellent mics with XLr leads.

Maybe worth hiring also instead of you spending lots
