The Pentax K-S1 does not look like your typical DSLR. Not just because the 20 megapixel camera is available in the sort of variety of colors we've come to expect from Pentax. But because it also features an intriguing illumination interface with LEDs built into the camera body to indicate its current status of operation, count down for a self-timer or show the number of faces identified in a shot.

Though the futuristic look of the Pentax K-S1 is certainly an attention grabber, the camera also boasts some solid photographic credentials. There's a 20 megapixel APS-C (23.5 x 15.6 mm) CMOS sensor which is paired with a Prime M II image processor. While the sensor has a low-pass filterless design for sharper images, the K-S1 uses the same anti-aliasing simulator as the K-3 to reduce moiré. In-body shake reduction is also on hand to help combat wobble-induced blurry shots.

An ISO range of 100 to 51,200 means that the K-S1 can be used in low light situations, and it also has a continuous shooting top speed of 5.4 fps. Autofocus is handled by a SAFOX IX i+ AF system with 11 focus points, 9 of which are cross type. Full HD 1080p video recording is possible at 30/25/24 fps, and in HD 720p this is upped to 60/50 fps.

Though the K-S1 is available in a total of 12 colors, it's the use of in-body LEDs which sets it apart from other cameras in terms of design. Five LEDs along the camera grip can be used as a countdown for a self-timer, show the number of faces recognized in a shot, or indicate remote control. Meanwhile, a ring around the shutter button glows green to indicate it's ready to shoot still images, or red for movies.

The use of LEDs doesn't stop there, on the rear is a mode dial which lights up green to show the camera's mode settings, and a big OK button that glows blue when shutter release is available. Also on the back of the camera is an optical viewfinder and a 3-inch LCD monitor with 921K dots, which has a new simple and straightforward graphical user interface.

The K-S1 uses the Pentax KAF2 bayonet mount and measures 120 x 93 x 70 mm (4.7 x 3.7 x 2.8 in) and weighs 558 g (19.7 oz). Though the camera lacks built-in Wi-Fi, it is compatible with Pentax Flucard memory cards for wireless transfer, along with remote live view and capture from smartphones, tablets or computers.

The Pentax K-S1 will be available in September for US$750 body-only, or bundled with a 18-55-mm kit lens for $800.
