Compact Design. Bright Inspiration.
Experience photography in a new light with the PENTAX K-S1. Whether you’re new to photography
or a skilled enthusiast, the K-S1 offers you the ability to take your imaging to the next
level. The K-S1 incorporates new elements that optimize digital innovations, such as a compact,
modern design and an inventive interface system. The addition of LED lights adds brilliance to
its exterior, while enhancing functionality. The K-S1 also provides other outstanding features,
rivaling those of high-end models, including: the PENTAX-developed anti-aliasing filter
simulator (first incorporated on the PENTAX K-3), an optical viewfinder with a glass pentaprism
to provide approximately 100% field of view, and an in-body shake reduction mechanism. If
you’re looking to upgrade your mobile photography, the PENTAX K-S1 is sure to smooth the
transition with compactness, style and outstanding performance.
Highlights:
Compact design
20 megapixels
5.4 fps continuous shooting
AA Filter Simulator
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.
High-Resolution Images.
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.
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.
