Right now I have a 7mp Pentax Optio M20. It's a great camera if you are close up and dont zoom. It's VERY clear. But, as soon as I zoom in, it's awful. Blurry very bad. Do you have any recommendations on a camera that you can zoom in far and the photo is still very clear? It would be much easier to catch those cute doggy moments if I didn't have to get right up in their face lol. Oh..and what is the difference between digital and optical zoom?!
