20MP stabilised CMOS sensor with AA filter-less
Sensitivity up to 51200 ISO
Full HD recording with 30fps frame rate
Continuos shooting at 5.4fps
Shutter speed 1/6000sec
The Pentax K-S1
Intelligent functions capture light with complete freedom for a
satisfying shot. The light interface “Indicator Lamps” intuitively guide
Anti-Aliasing Filter Simulator
The low-pass filterless design maximises resolution from the
CMOS image sensor. This model is also equipped with the Pentax-original
Anti-Aliasing Filter Simulator function which reduces moiré that occurs
due to tiny drive operations of the sensor. Two merits are obtained from
this one unit.
*Sufficient effects are obtained when shooting at shutter speeds
slower than 1/1000 sec. Also, this function cannot be used when taking
The Indicator Lamps use LED to display camera status. This use
of light provides intuitive camera control. The design floats like a
light display for a sense of presence.
Main switch: Green for still images, and red for movies
Grip: The 5 lights in a line display a countdown for Face Detection, Remote Control, and Self-timer.
Mode dial: The currently set mode appears in green. When shutter release is available, the OK button is lit in blue.
With the CMOS image sensor and Prime M II image processor, high
sensitivity of ISO 51200 is achieved. This feature shows its true
ability when shooting in dark scenes that were not possible with
Simple GUI (Graphical User Interface)
A GUI design is used so setting content for each function can be understood at a glance.
Moving explanations and easy-to-understand displays make controls easier.
Optical viewfinder with approx. 100% field of view
A glass prism finder is used with the same specs as those found
on Pentax high end cameras. With the large, easy to use viewfinder with
an approximate 100% field of view and approximate 0.95x* magnification
(viewfinder magnification), focusing and composing shots are easier,
letting you focus on the subject.
The main body unit portrays a sharp and feel, whereas the light
path that contains the traditional pentaprism is very much like an
authentic SLR. By combining two differing shapes into a fusion design, a
compact, lightweight camera that fits in the palm of the hand is
