Photography without limits
The PENTAX K10D opens new perspectives to you,
the photographer, with maximum speed and maximum
performance. This camera produces images more
rapidly, more precisely, and more realistically than
any other digital SLR in its class. All components and
functions are attuned to the highest photographic
requirements. The K10D can shoot up to 3 fps – with
a resolution of 10 megapixels. Recording delays are
virtually non-existent because the new PRIME (PENTAX
Real IMage Engine) image processing system calculates the graphic data with remarkable speed. Brilliance
in sharpness and color, as well as simplicity in operation and comfort are always there. Further intelligent
systems include supersonic direct-drive technology
for ultrafast focusing, “Dust Reduction” (DR) to help
eliminate the fine dust particles on the CCD and “Shake
Reduction” for blur-free photographs. All these features
allow you to concentrate on what is really important:
creative perfection.

Shake Reduction
The PENTAX-developed “Shake Reduction”
technology solves one of the oldest photographic
problems: blur caused by handheld camera
shake. The K10D produces sharp photos in
challenging situations without having to use a
tripod. Hand-held photography is now possible
with long telephoto lenses or when long exposure times are required due to poor lighting.
The PENTAX “Shake Reduction” system is
integrated into the camera body and is independent of the lens in use. The principle behind
its operation is simple: movement sensors in
the body recognize camera shake. The system
ensures that at the moment of exposure the
compensating movement of the CCD sensor
provides blur-free pictures.
The advantage is obvious: you can increase your
hand-held shooting by 2.5 to 4 stops.
If you are intentionally moving the camera when
shooting – while panning with a Formula 1 race
car along the track, for example – you can simply
deactivate the “Shake Reduction” system.
PENTAX has filed for over 30 patents for this
SR system, which uses a ball-bearing-mounted
oscillator unit with four electromagnets that
position the free-floating image sensor. Angular
velocity sensors detect camera movement and
relay the amount of compensation necessary
to the electromagnets that move the sensor to
compensate for any shake.
The Shake Reduction unit consists of
the rear bearing plate, the central plate
containing the CCD and controlling
electromagnets, and the front plate
containing the permanent magnets.

10 Megapixels
The 23.5 x 15.7mm CCD sensor records
photos with a resolution of up to 10 megapixels. This is enough for you to produce
truly astounding prints even at 20 x 30
inches or more without difficulty.
22 Bit A/D Converter
Analog information from the K10D’s 10
megapixel CCD is delivered over two
channels to the 22 bit analog-to-digital
converters, where the image information is
transformed from an analog signal to digital
data. This new technology affords a substantially higher dynamic range resulting in finer
tuning of colors compared to conventional
12 bit converters. With this new technology
PENTAX is again a step ahead of the market.
The photographer is the winner: digital
pictures are now virtually indistinguishable
from analog film pictures in terms of color
and dynamic range.
