How Do I Get Sound On Olympus Camedia D-435?

The D435 captures video without sound and there's no way to use an external mic or anything like that. You'll need to replace it if you want movies with sound. There are loads of questions and answers on here about cameras that do movies and movie cameras so take a look around and see what you fancy. A word of warning. The $50 HD movie cameras aren't very good. Give yourself a budget of at least $125.
