Pentax 02 is a standard zoom lens with 3 times zoom range and 5 to 15mm native angles. The aperture is f/4.5 at full zoom and f/2.8 at the widest setting. At any focal range, photographers can focus on an object as close as 12 inches.
The lens itself weighs nearly 3.5 ounces and about 1.9 x 1.9 inches in size. Even in very bright light, users can shoot at relatively low shutter speeds thanks to the integrated neutral density filter. The responsive leaf shutter is responsive enough to sync with the flash at 1/2000 second.
