good point from Scottishscript!
We all want a camera that will take a good photo, maybe even a great one! but the point about the Scottish weather is a valid one! one point to consider , and I have not seen it in any spec for a camera ( yet! ) is the temperature range it will operate in! Quite annoying to find out when you are halfway up a hill that your camera will not operate ( that's funny it was working at the car park! ) So maybe small is the answer , where it can be kept in an inside pocket or an insulated camera pouch at a reasonable temperature
