camera’s unique flat field user interface, which integrates a back-lit
LED selection dial, four-way navigation, and a bright 3” 921,000 dot LCD
that breaks tradition of the knobs and buttons found on traditional
The PENTAX K-S1 is designed to attract a mid-level customer who is
accustomed to a mobile interface and is looking for a similar
interaction in a DSLR. The simple UI eliminates many of the complexities
of a DSLR and provides immediate feedback including shooting
parameters, filter selection and effect modes, even in total darkness.
The camera’s power switch, mode dial, OK button and grip all feature LED
illumination; each of which indicates the current status of camera
operation. This intuitive UI and design combined with category leading
technology delivers a powerful imaging engine that is simple to use.
“With the K-S1 we are building on our solid reputation as a camera
company and inviting new customers to experience the PENTAX advantage”
said Jim Malcolm, Executive Vice President, Ricoh Imaging Americas
Corporation. “Our core PENTAX products provide an important foundation
that the K-S1 builds upon.”
The optional Flucard for PENTAX offers additional features such as Wi-Fi
transfer, wireless live view, and Remote Capture control; letting users
take control of their camera settings with a smartphone, tablet, or
computer and save images directly to a mobile device.
The K-S1 comes in 3 standard colors: black, blue, and white. In
addition, two separate color collections are available; The Fabric
Collection, containing 4 unique colors such as cotton beige and tweed
gray – and the Night Sky Collection, with 5 more elegant colors like
Sunset Orange, Dawn Purple, and Midnight Black.

Pricing and Availability
The PENTAX K-S1 kit including an 18-55 mm lens will be available at
retailers nationwide and at www.us.ricoh-imaging.com in September 2014
for a suggested retail price of $799.95. The K-S1 body only will be
available for $749.95.
• Illuminated Interface for intuitive camera operation
The PENTAX K-S1’s power switch, mode dial, OK button and grip all
feature LED illumination; each of which indicates the current status of
camera operation. The LEDs for the power switch, for instance, stay
green during still-image shooting, but change color to red during movie
recording. When the Face Detection function is activated, the number of
LEDs illuminated on the grip corresponds with the number of faces that
have been detected. The grip LEDs also act as a countdown timer during
self timer operation. This LED body illumination gives a decorative
illumination to the choice of distinctive body colors; furthering the
look of the camera as a sophisticated digital device.
• Compact, lightweight body with distinctive design
The K-S1 camera body’s main chassis, including the grip, is designed to
be compact in size and sophisticated in appearance, while the pentaprism
employs a solid, time-proven design that easily matches high-grade SLR
cameras. By harmonizing these dissimilar elements, the K-S1 delivers a
body design that is totally original and remarkably fashionable.
Note: This product design was developed in collaboration with and under
supervision for design and color of Ziba Tokyo, Co., Ltd., the Tokyo
branch of a design consultant firm Ziba, headquartered in Portland,
Oregon, USA, and with other branches in Munich and San Diego.
• High-resolution images produced by the 20.12 megapixel CMOS sensor with a super-high sensitivity of ISO 51200
The K-S1 is equipped with a newly developed CMOS image sensor with
approximately 20.12 effective megapixels to deliver
super-high-resolution images. It is also designed without an optical AA
(anti-aliasing) filter to optimize the imaging power of the sensor. By
coupling this image sensor with the high-performance PRIME MII imaging
engine, the K-S1 delivers true-to-life, detailed images by effectively
minimizing noise at all sensitivity levels, even during
super-high-sensitivity shooting at ISO 51200.
• In-body shake reduction (SR) mechanism, and AA (anti-aliasing) filter simulator for effective moiré reduction
(1) In-body SR (Shake Reduction) mechanism
The K-S1 features the PENTAX-developed SR (Shake Reduction) mechanism to
effectively minimize camera shake and assure sharp, blur-free images,
even in camera-shake-prone conditions such as when using a telephoto
lens, shooting low-light scenes with incident light only, or
photographing sunset scenes.
(2) Innovative AA (anti-aliasing) filter simulator*
By applying microscopic vibrations to the image sensor unit at the
sub-pixel level during image exposure, the K-S1’s AA filter simulator
provides the same level of moiré-reduction effect as an optical AA
filter. Unlike an optical AA filter, which always creates the same
result, this innovative simulator lets the user not only switch the AA
filter effect on and off, but also adjust the level of the effect
(3) ASTRO TRACER support
The K-S1’s SR unit has a flexible design that shifts the image senor
horizontally (left/right), vertically (up/down), and rotationally.
Taking advantage of this flexibility, the K-S1 provides a host of handy
shooting functions, including ASTRO TRACER, which simplifies advanced
astronomical photography in combination with the optional GPS unit,
* This function is most effective with a shutter speed of 1/1000 second
or slower. This function is not available during HDR (High Dynamic
• Optical viewfinder with 100-percent field of view
The K-S1 is equipped with a glass pentaprism finder featuring the same
optics and coatings as those used in higher-level models. It assures the
highest level of viewfinder brightness in its class, with a
magnification of approximately 0.95 times to provide a broad image field
for easy focusing and framing.
• High-speed shutter to capture fast-moving subjects in crisp focus
The K-S1 provides a top shutter speed of 1/6000 second to capture the
decisive moment. Coupled with its high-speed continuous shooting
function (with a top speed of 5.4 images per second), it lets the
photographer freeze once-in-a-lifetime shutter opportunities.
• High-precision AF with SAFOX IXi+ AF sensor module
The K-S1 features the SAFOX IXi+ AF sensor module, which assures
responsive, high-precision autofocus operation with 11 sensors,
including nine cross-type sensors. It also provides a spot beam to
assist AF operation in poorly lit locations. Its select-area expansion
function ensures that the sensor module keeps tracking a moving subject,
even when the subject moves out of a pre-assigned auto-tracking area,
by assessing the distance data collected by neighboring focus sensors.
The AF hold function maintains the in-focus position, even when the AF
system loses track of the subject after once capturing it in focus.
These functions combine to improve the camera's accuracy in the
detection of moving subjects when its focus mode is set to AUTO, and
upgrade its auto-tracking performance of these subjects when using a
• A selection of image-processing tools for creative, personalized expressions
By setting the Mode dial to the EFFECT position, the user can apply the
desired visual effect to an image while previewing the outcome on the
LCD monitor. It provides a choice of 10 distinctive effects, including
three new options: “Fresh” with a crystal-clean finishing touch; “Fade
Color” for an elegant finish with subdued colors; and “Infrared” for a
black-and-white finish like that of an infrared photo. The K-S1 also
provides 21 digital filters (nine of them applicable during shooting),
including a new “Color Replacement” filter.
• Dependable lens aberration compensation system
In addition to the effective compensation for distortion, chromatic
aberration and peripheral brightness, the K-S1 also provides
compensation function for diffraction, which deteriorates image
resolution when a small aperture is used.
• Connected device functions**
The optional FLUCARD FOR PENTAX 16GB memory card can release the K-S1’s
shutter, provide a live-view image, and browse and download the images
recorded on the card using a smartphone or other wireless and web
browser enabled device.
** These functions support smartphones operating iOS6 or later and Android 4.2 or later.
• 3.0-inch, high-resolution LCD monitor, and newly designed, easy-to-use interface
The K-S1 features a high-resolution, wide-view LCD monitor with
approximately 921,000 dots. It also provides a status screen employing
the newly-designed GUI (Graphical User Interface), which allows the user
to confirm functions and settings assigned to the four-way controller
and the OK button at a glance. The RICOH RT font has been used for
on-screen menus to improve readability.
• Full HD movie recording with stereo audio
The K-S1 captures beautiful Full HD movie clips (1920 x 1080 pixels;
30/25/24 frame rate) in the H.264 recording format, which assures
flawless, high-quality movies even with fast-moving subjects. It is also
equipped with a built-in stereo microphone for recording natural sound
during Full HD movie recording.
• Color Options
The K-S1 comes in 12 different colors: The standard colors: black,
blue, and white. The Fabric Collection: Cotton Beige, Linen Brown, Denim
Blue, and Tweed Gray. The Night Sky Collection: Sunset Orange, Dusk
Gold, Moon Silver, Midnight Black, Dawn Purple.
