Wide angle--- most consumer cams' lenses are not wide enough. A wide angle (WA) adaptor is recommended. Spend the extra one on one with a glass lens. Any current cam will have the ability to accept a WA. The lens screw of a camera may have a diameter of 38mm. You'll match that diameter to the range of WA's (and adaptors if your cam uses an odd size) available. Very simple and easy.
What are the specs I should be looking for on these WA glass lenses? For instance I see one with .45X... what is the best general power for taking casting video, in your opinion (which I totally trust!)
that's a great idea I have been thinking about that resource for a while now especially for free access cable programming of volunteer kids events in the community etc.
