It is unfair to wait right until the end and then introduce yet another camera into the mix but there is another camera, which is more expensive but which otherwise overlaps all of the others compared here. The Sony Cybershot DSC-RX100. Here there is one major difference, which is that the sensor is much larger: it is a 20 Megapixel sensor measuring 8.8mm by 13.2mm, but the equivalent focal length range is similar, 28-100mm.
Is this fair? The Sony is quite a bit more expensive, between 30 and 50% depending on where you are, but the performance of the RX100 is so good that this higher price is probably justified. A DxOMark score of 66, 18 higher than the EX2F, 22.6 bits of color depth, 2.6 better than the EX2F, 12.4 Evs of dynamic range, 0.9 of a stop better and 390 ISO, just under a stop again. The Sony is also smaller and lighter and it has full HD Video up to 60fps. On the down side: it does not have the WiFi and the lens is not quite as fast. If you have a tight budget then the Samsung EX2F is a well specified camera for the money, there are a couple of things that make it very interesting, especially the f1.4 lens, it would be even nicer if the aperture were fixed through the range. Other cameras in this sector do other things better, the Nikon Coolpix has a better zoom range, the Fuji XF1 looks nicer and so on, but if you want a camera to fit in your pocket and to give you the best possible images I’m afraid I would be getting my credit card out and paying the extra for a Sony DSC RX100.
