I've been looking for a digital camera and there are so many choices out there. I'm looking for something between $300-400 and around 4 mp. I'll be using the camera for mountain biking shots, nature scenes, and taking pictures of people. I want an optical zoom and the more features the better, like some manual modes ect. Size is sort of an issue as I want to carry the camera on mountain bike rides.
I was looking at these cameras:
Canon Powershot A80

Olympus C750 Ultra Zoom

Canon Poweshot S400

Are these good cameras for what I'm looking for, are there any others I should look at and what would you choose?
