With 14.6 megapixels, it's the highest in its class.
Improving on the technology of the award winning K10D, the flagship
Pentax K20D is the highest-resolution camera in the advanced photo enthusiast
category and allows more experienced photographers, who demand complete control,
to fully customize the camera.
Newly Developed CMOS Image Sensor
The Pentax K20D features a newly developed CMOS (complementary metal
oxide semiconductor) image sensor measuring 23.4 mm x 15.6 mm. In designing the
K20D, Pentax made the significant transition to a higher resolution 14.6
megapixel sensor, rivaling the detail previously only found in images captured
with 35mm film. This considerable gain offers 50 percent more resolution than 10
megapixel sensors, and 20 percent more resolution than 12 megapixel sensors.
Pentax Imaging (a leading innovator in the imaging business) collaborated with
Samsung Electronics (a market leader in developing and producing semiconductors)
in the development of the 14.6 megapixel CMOS Sensor found in the Pentax K20D
Digital SLR. The larger photo diode in the sensor gathers more light in a
shorter time and therefore can respond more sensitively. As a result, the K20D
is able to achieve higher sensitivity levels (up to 6400 in the expanded ISO
mode). Also, there is a more direct light path to the pixels. Coupled with a
high-performance imaging engine incorporating Pentax-original image-processing
technologies programmed to yield natural, true-to-life images, the new model
assures fine-detailed, rich-gradation images.
Pentax Original Shake Reduction mechanism
The K20D is equipped with the Pentax-developed Shake Reduction mechanism, which
reduces camera shake for sharp, blur-free images even under demanding shooting
conditions, such as shooting with a telephoto lens, shooting in low light
conditions or at night without supplementary flash illumination, or using
extended exposures for sunset scenes. This innovative mechanism offers
outstanding compensation equivalent to approximately 2.5 to 4 shutter-speed
steps. In addition, the lighter image sensor unit and refined data-control
algorithm offer improved image stabilization over previous models. Pentax Shake
Reduction is compatible with existing Pentax interchangeable lenses.
Large, 2.7-inch wide-view LCD monitor
The K20D features a large 2.7 inch color LCD monitor. The wide-view design
allows the photographer to view the monitor image from approximately 160 degrees
both vertically and horizontally. Since it assures effortless image viewing from
a diagonal position, it facilitates low- and high-angle shooting using the Live
View function.
New Live View function
The K20D features a Live View function that allows users to view an image on the
LCD monitor during shooting. This feature is beneficial when the photographer
moves his or her eye from the viewfinder in specialized applications, such as
low and high-angle shooting, or when perfecting composition. The function also
allows users to confirm the Shake-Reduction effect on the monitor while
shooting.
High-performance, high-speed PRIME Imaging Engine
The K20D incorporates the Pentax-original PRIME (Pentax Real IMage Engine).
Designed exclusively for Pentax digital SLR cameras, the engine ensures
well-balanced, true-to-life images with faithful color reproduction by
efficiently controlling digital signals transmitted by the CMOS image sensor. It
also allows complete control over other photographic factors including white
balance and the new Custom Image functions. This imaging engine also features a
Double Data Rate 2 (DDR2) memory to assure speedy image processing and
high-speed data transfer.
Custom Image function
The K20D is equipped with a new Custom Image function that lets the user select
one of the six modes and adjust an image's processing to their preference by
automatically adjusting tone, saturation, contrast, and sharpness. These modes
include Natural, Bright, Portrait, Landscape, Vibrant, and B&W image modes. The
photographer can make further fine-tuned adjustments to each setting. The effect
on each of the primary colors is shown in a radar-type display on the LCD panel.
The user can easily see the effect of their adjustments by using the digital
preview option.
Expanded Dynamic Range Function
The K20D adds a dynamic-range expansion function, which allows the user to
expand the dynamic range (or range of gradation reproduction) while retaining
the proper contrast to avoid white-washed areas. With an approximately 1EV
expansion effect, it assures beautiful, rich-gradation images.
Dust-proof, water-resistant construction
The K20D boasts an extremely reliable weather-resistant and dust-proof
construction with special seals applied to 72 different parts of the camera
body, including the shutter release button and all the switches, levers, dials.
This dependable body makes it possible to use the K20D in the rain or dusty
locations without worries.
Comprehensive Dust Removal System With Prevention, Removal and Alerting
Devices
The K20D features the user-friendly Dust Removal system to prevent dust from
sticking to the surface of the CMOS image sensor (or low-pass filter). The
Pentax-original Super Protect (SP) coating, applied to the image sensor surface
through vapor deposition of a fluorine compound, effectively prevents dust from
sticking to the surface. In the next step, dust that may remain on the surface
will be shaken off when the system shifts the image sensor at high speed.
Finally, the dust that is shaken off the image sensor falls onto an adhesive
strip positioned at the bottom of the unit, eliminating any possibility of the
dust returning to the image sensor surface. This upgraded Dust Reduction system
also offers a new Dust Alert function, which shows the user exactly where dust
may be sticking to the sensor surface.
Hyper Program Function
The K20D's Hyper Program function allows users to instantly switch to the
Shutter-Priority or Aperture-Priority AE mode from the Programmed AE mode with a
simple turn of the electronic dials on the grip. To return to the Programmed AE
mode, simply press the green button positioned next to the shutter release
button.
Hyper Manual Function
When shooting in Manual mode, one push of the green button allows the user to
instantly set the proper exposure for the subject.
Sensitivity-Priority mode
The K20D features a unique Sensitivity-Priority (Sv) mode designed to
automatically select the optimum combination of aperture and shutter speed for a
user-selected sensitivity. The sensitivity can be shifted instantly in 1/2 or
1/3 steps by turning the electronic dial on the back panel.
Shutter/Aperture-Priority mode
Taking full advantage of the unique capability of digital cameras, which permit
automatic shift of sensitivity at any time, the Shutter/Aperture-Priority (TAv)
mode automatically selects the most appropriate sensitivity for a user-selected
shutter-speed/aperture combination. This mode allows users to experiment with a
greater range of photographic expressions with greater ease.
Bright, clear viewfinder
Featuring a glass pentaprism, the K20D's viewfinder offers an approximately 95
percent field of view and an approximately 0.95x magnification for easy viewing
of the subject and effortless confirmation of focus and composition. Coupled
with the acclaimed Natural-Bright-Matte II focusing screen, it delivers a large,
bright subject image.
Continuous shooting at approximately three images per second
To trace the movement of an active subject or capture a sequence of the
subject's expressions, the K20D offers a continuous shooting mode that allows
the photographer to capture as many as 38 images in succession (in JPEG
recording format) at a maximum speed of approximately three images (frames) per
second. When switched to the new high-speed advance mode, the user may capture
up to approximately 115 images at the speed of approximately 21 images per
second.
High-precision 11-point wide-frame AF
The K20D's sophisticated SAFOX VIII autofocus system features 11 sensor points
(with nine cross-type sensors) to automatically focus on the subject with utmost
precision, even when it is positioned off center. When the subject is captured
in focus, the in-focus sensor point is automatically superimposed in red in the
viewfinder for at-a-glance confirmation.
Powerful rechargeable batteries
The K20D features large capacity Lithium-ion rechargeable batteries, which can
capture approximately 740 images when fully charged. The dramatically improved
battery capacity (over the previous K10D) is the result of a new energy saving
design.
