im by no means a camera pro, more like a practiced novice but heres what ive learned.
if you are going to be taking long shots youll want something like a megazoom camera, i have a canon sx20is that has 20x optical zoom and a 4x digital zoom works great for the long shots
but if youre a bit closer and want more of a pocket camera i think any smaller point and shoot type will work well, i have a canon A590is that takes great pics has 4x optical and 4x digital zoom. both cameras have all the idiot modes and the more advanced mode options including full manual
just for to show what one camera is capable of, this pic was shot about an hour ago with the sx20is at a distance of 0.5 mile at 80x zoom in snow shot mode, have not done any post processing
