firstly i know little about digital camera, hence i am seeking help here. i am after a new P&S camera, with a budget around 300 dollars. now before i ask for suggestions, i want to know a little about optical zoom. most camera in my budget range only has 3X zoom, which may not be enough for me. because my current camera is Canon ixus 750 with 3 zoom (7.7-23.1mm 1:2.8-4.9). i found the zoom distance is pretty average or even hopeless in some cases. recently i went on a tour bus, and while i try to shoot certain far away object, i get tiny image on the longest zoom, while other ppl can get real close. as a result i want a better camera with better zoom. also can someone explain a bit about those values about zoom? so when i go to camera shop, i can understand them, maybe compare them? one more question is: during night shot, even with night shot mode on, with high iso on, image i took is really grainy and fuzzy (this is with sony DSC-T2), so only tripot is the way for night shot? last but not least, what camera do you recommend?
