I wants somthing that I can go for a horseback ride with.

I am a beginner. I want a camera that I don't have to worry about when I ride. So it needs to be small. I also need it to be quick as my horse doesn't always stay still for a long period of time. I would be taking lots of outdoor pictures, but I also would be taking indoor and close up pictures as well. Having good pictures is important to me.
