Greetings! My son is interest in creating videos, casting his friends. I use a Canon 7D, but sound and manual exposure and controls are way too complicated for him. Understandably, he wants to grab and go. Also, there's the "boys will be boys" aspect. So I'm looking for something not too complicated. This is his reward for getting straight-A's this year at school, but I am on a budget. I looking for something under $700. Thanks!
