First things first: Pentax calls this “the smallest, lightest interchangeable lens camera in the world,” and they’re dead right. This camera is small. You thought your micro four-thirds camera was small, but it’s huge compared to the Pentax Q. It’s hard to appreciate just how small it is, until you put it next to something else that’s really small. Like an iPhone.
As you can see, the Q sits neatly atop the iPhone’s screen, not even touching the edges of its case. It’s tiny.
