one thing to watch out for,when using the zoom button,dont just let it go after you zoom,or it will click and the noise will be recorded. however,if you edit and can dub different audio then it wont matter. that said, we love the camera.ive been thinking about an off board mic for sterio audio,,just for fun. but since this camera is kinda old now,finding extra parts is kinda tough. when we bought it,they were just comming out and then everything was available,but now,several years later,,, well they arent. ebay or maybe canon outlet in the usa.in fact i just bid on a remote for it,we lost the other one. man,they come in handy.id probly also want a clear over lense to protect the main lense from grit and crud. cheaper to get a new cover than new lense.

Ex Output:
Positive

The great thing about this book is it works as a nonfiction book, if you're a believer and as a book of fiction, if you're a nonbeliever.If you believe in UFO's and monsters, the interviews with the people sound very sincere and convincing.If you don't believe in the subject, the book reads like a good horror novel with a tragic ending which is based on a true event

Ex Output:

Positive
