'For those looking for an ultra small compact system camera, the Pentax QS-1 is a reasonable option, especially if you've got some kind of affinity to the Pentax brand. '

Unless you can find the Nikon 1 S2 at a ridiculously low price, we suggest you spend a little more money on stronger mirrorless cameras like Sony’s A5000.
