okay... so my uncle is looking for a great camera to take back to mexico with him. he travels a lot! so he'll need the camera to take great low light pictures. he keeps asking what optical zoom is and i don't really know how to explain that. he doesn't want a camera that's all big either. he would prefer one of those thin ones and prefer for it to be able to record video and sound as well. he says the higher the optical zoom is, the better. and i say the higher the mega pixels, the better. so if there's both! then that's great!!! :) brand names and the model please... if you could give a link, that would be appreciated.
thanks for your help!
