Hi, you may have seen my previous post, and thanks to most of you, I think I have narrowed it down some. I think that the Canon SX210 IS, Canon ELPH300 HS, or Canon SD1400 IS, maybe good for me and my family, but I need your help. My main needs are: 1. Good pictures in bad lighting/dark. 2. Good motion pictures for sports. 3. Good battery life (oh and what is the best kind of battery- is lithion ion good)? 4. A zoom that actually helps. (by good ^^^ I mean about 3-4 stars out of 5 being the best) Questions: 1. Do you want a higher megapixel number? 2. What is the F.# do? 3. Are the choices I chose good cameras that do the work, or is something else better for my buck? Budget: I would like to keep it under $280 (I found where I can get the SX210 for $260). Thank you so much again for all of your previous help, when I look at all the cameras out there, I get so confused and nervous. Your help is very much appreciated! Thanks again!
