If your really keen, and do not mind the expense, a GoPro Hero 4 Silver would be a great camera for the outdoors.
Its tiny dimensions and pocketability, are perfect for a take anywhere camera, and it can play and record video in 4k quality.
There are numerous digital cameras on the market, that outperform the GoPros for less money, but very few of them are guaranteed 100% water and condensation proof, down to 30m depth of water.
We all know how unpredictable the British weather can be, and having a camera where you can take crystal clear photographs and video in driving rain, is a big bonus, even if you know that the kind of photographs your likely to take are fine weather ones, having a camera you can take to the hills in any weather, is a big bonus.
Just imagine if you saw a particular photograph in less than ideal conditions, using a normal digital camera would be out of the question.
