I searched throughout the boards, and while some members mentioned taping from the lawn, I couldn't find any comments on whether or not it was a good idea, or any reviews on how their recordings came out.
So, is it possible to achieve good results when taping from the lawn? I'm thinking about hitting up 106.5 The End's Weenie Roast 2012, and capturing Garbage and Coheed, if not the others as well. Also thinking about capturing Aerosmith's tour with Cheap Trick, both shows of which I would only be able to afford the lawn. I will be using a Panasonic Lumix DMC-FZ150 to capture video in 1080/60 progressive, and either using an external mic plugged into the camera or an audio rig to capture the audio.
Now, let me explain my reasoning for recording from the lawn. For one, it's a hell of a lot cheaper. The camera I will be using was $450, so yea, I'm tapped for awhile. The camera has 24x optical zoom, so getting close to the action video wise will not be a problem at all. It's the audio I'm worried about. Even if I was "front row" on the lawn, would I be able to get a decent audio capture, or will I be positioned too far away? The other plus to my set up is that the camera is just that, a camera. Not a camcorder. And since it doesn't have a detachable lens, it's not considered professional by most venues, so they allow it. No one ever said super zooms were not allowed.

But yes, any opinion and suggestions in regards to getting the best audio I can from the lawn would be greatly appreciated!
