Don't talk to me about mics.
Thye sound quality is the biggest difficulty for film-makers. They don't have a man with a big furry squirrel on a pole for the fun of it. I got through, IIRC, 11 microphones on Workshop Essentials 1 and 2. I tried two different radio mics, the second one being fairly expensive, but it simply didn't work well in the workshop. Where I stood I was next to a big chunk of cast iron, and if I wasn't then the receiver was. It played havoc with the signal. In the end I used a £20 mic from Maplins and that gave good results. It does mean that the sound quality is a bit variable, especially in the earlier scenes (bear in mind we shot from October to June).
The downside of using such a mic is that you are tethered to the camera and it is very easy to forget that...... The other problem is that presenting something like woodwork or any other practical subject where you are moving your head is that it is easy to pop, which really does sound awful. A fluffy cover helps
For WE3 I used the mic that is built in to the camera. Very good clarity, but the volume changes depending on my distance from the camera, so I have to normalize the gain for every scene when I edit. I also get a constant slight hum. This is the noise of the camera motor being picked up and it is not easy to remove without affecting the voice.
I'd have thought that the camera mic would be fine for a Podcast.
