i want to get a digital camera to bring on the trails with me. i can't really afford to spend more than 400, i'd like to keep it under 300 if possible. i need something that's good for taking riding shots (duh). the hardest thing to deal with on most cameras is the shutter lag; it always makes taking a action shot more difficult, so a short lag time is one of the key things i'm looking for. so give me some suggestions please. what are you guys using to take pics?
