Pentax Q S-1, Is this World's Smallest Interchangeable Lens Camera?

Is smaller better when it comes to prosumer camera with interchangeable lens system?  Sure, why not, as long as the image quality does not suffer from the small form factor.

Since its first announcement, the biggest attention grabbing factor for the Pentax Q-series cameras has been their minuscule size and interchangeable lenses. Now, Pentax Q-S1 is official with pricing details.

Unfortunately, Pentax Q S-1 may not claim the title of being the world's smallest interchangeable lens camera.  That title still goes to Panasonic GM1 which has even bigger sensor - Micro Four Thirds.

The sensor in Q-S1 is a 12.4-megapixels backside-illuminated CMOS with a maximum ISO of 12,800. It uses a 1/1.7-inch sensor (similar to that of the Q7) with built-in shake reduction.
There is no doubt that this camera will make a big fashion statement.  It look quite attractive and looks unlike any camera in the market today.  It even offers an array of super cute  color choices; 4 standard body colors and 36 more body and grip colors!

Another welcoming news is the price of this charming little camera.  It's priced at $449 which is probably lower than most if not all interchangeable lens cameras from well known brands.
