Expanding its DSLR lineup, Pentax has just announced the new Pentax K-S1. Boasting a compact contemporary design and intuitive user interface, the K-S1 20MP camera offers some of the unique features of its big brother, the Pentax K-3, but adds some refinements on the inside and out.
On the inside, the K-S1 features a new 20MP APS-C CMOS sensor that feeds still image or full 1080p h.264 HD video data through a brand new PRIME M II Image Processing Engine. The sensor helps the K-S1 capture images in very low light, with sensitivity ranging from ISO 100 up to ISO 51200.
The most interesting features might be on the outside of this camera. Beside the bright body colors available for the K-S1, the camera features some eye-catching LED-illuminated buttons and camera controls along with LED indicator lamps in the handgrip that give it a little bit of visual "wow” factor while adding to the functionality of the camera. The shutter release is surrounded by an illuminated ring and the multi-function control wheel and buttons on the rear also glow to assist the shooter in selecting modes and navigating menus.
For shooting, the camera can capture action at 5.4 frames per second at shutter speeds up to 1/6000 of a second. To help keep subjects sharp, the camera features a high-precision SAFOX IXi+ phase-matching autofocus system with 11 detection points, including 9 cross-type points in the center of the frame. The autofocus system sensitivity range is from EV 1 to EV 18 at ISO 100 and the system is assisted, as needed, by an LED autofocus assist lamp. Keeping things steady is an innovative in-body Shake Reduction (SR) mechanism, negating the need for image-stabilized lenses. The camera is compatible with Pentax K-mount lenses.
Sharing a unique-to-Pentax feature with the K-3, the K-S1 also offers the selectable anti-aliasing filter that allows you to toggle the anti-aliasing filter's effect either on or off, providing support for both the high-resolution abilities of a filter-less design as well as advanced moiré protection. Having both options available extends the camera's versatility and allows personalized selection of the benefits best-suited to individual applications.
The K-S1 features a bright 100%-coverage viewfinder with 0.95x magnification and a live-view-capable 921k-dot rear 3.0" LCD that is adjustable in brightness, saturation, and color. The live view can be magnified 2, 4, 8, or 10x and features three different grid options as well as a histogram and bright area warnings. Metering is handled by a 77-segment system with multi-, center-, and spot-metering options, and a built-in retractable flash provides extra light when needed. A built-in stereo microphone with adjustable recording level is featured for the HD movie recording.
Shoot RAW images with your K-S1, or use the internal processing power to do in-body RAW development, HDR shooting, or utilize one of nearly 30 specialized picture and scene modes including Macro, Portrait, Moving Object, Night Scene Portrait, Surf & Snow, Kids, Pet, Food, Backlight Silhouette, Stage Lighting, Museum, and more. Who needs Instagram when you can add specialized effects to your art inside the camera with any one of a dozen options, from Faded Color to Vintage Color to Bold Monochrome, and others?
By combining some exclusive features of the big-brother K-3, as well as many proven internal features of the K-5/K-500 cameras, the new K-S1, with its LED-illuminated trim and buttons, is sure to turn heads while it captures great images.
The K-S1 body can be purchased from B&H as a body-only in Black, White, or Blue, or as a single-lens kit with a Pentax 18-55mm f/3.5-5.6 lens or a dual-lens kit with the 18-55mm and Pentax 50-200mm f/4-5.6 lenses. Continuing the colorful trend of Pentax's other DSLR lines, the K-S1 one-lens kits are available in Black, White, Blue, Cotton Beige, Denim Blue, Dusk Gold, Dawn Purple, Linen Brown, Midnight Black, Moon Silver, Sunset Orange, and Tweed Gray.
