The new issue has an article review concerning new video cameras from cost to efficieny to compatibility.
I recommend you subscribe to it hard copy also as it explains video in laymans' terms from A to Z from camera work to audio to editing.
Rule 1. Buy the best you can afford. Don't be in a rush to just 'get a camera'. Study, research, read, compare, play with them at the dealers.
Rule 2. NEVER USE A DIGITAL ZOOM. Forget it's there. Disable it a user function if at all possible. If you want more 'distance'....learn about Depth of Field and use a mulitiplier or extender which usually can be bought as a screw on lens attachment.
Rule 3. Buy BALANCED audio. Learn what it is before you buy anything for your camera to record it.
Rule 4. Make sure your CAMERA is compatible with your COMPUTER PROGRAM for pictures, editing, cables, video capture cards, etc. etc.
A professional shop can help you get set up with that.

Research the camera, the format, the computer systems, the video signal transfer, the audio, the HUNDREDS of ACCESSORIES etc etc. before you turn loose of your hard earned dollars.

Good luck and have fun once you get started.
