Optical product maker Hoya Corp. said Thursday it will soon launch the world's smallest and lightest digital camera with an interchangeable lens.
The pocket-sized PENTAX Q is around 5.75 cm high, 9.8 cm wide and 3.1 cm deep, and weighs about 200 grams. It also has a function that allows finishing touches to be added to an image while previewing the effect on a display.
