Click on the second page of the chart we can see the Pentax Q (White/Prime Kit) is there, at the top!
The sales of the Black Q Kit is not bad, neither. It is positioned at no. 17, just right behind the Sony NEX-C3 standard twin-lens kit in silver, which is also sold at exactly the same price as the Q single prime lens kit.
Congrats, Pentax! I think this is the ever biggest sales and marketing victory of Pentax in these ten years or so! And, a bigger sensor is not needed and the real IQ is of second concern, coz marketing tricks could prevail. Anyway, at a price of JPY 69,800 (~US$7k) let's see if the good sales of the Q will continue and persist.
