An Easy-to-Operate, Entry-Class Digital SLR Camera Featuring Shake Reduction, Scene-Specific Shooting Modes and an Array of User-Friendly Functions
in a Compact, Lightweight Body
HOYA CORPORATION PENTAX Products is pleased to announce the launch of the PENTAX K-m digital SLR camera. Designed primarily for beginning digital SLR photographers, this new entry-class model offers simplified, user-friendly operation, and an easy-to-maneuver compact, lightweight body.
The PENTAX K-m was developed as an entry-class digital SLR camera offering simple, straightforward operation, making it possible for first-time digital SLR users and family photographers to enjoy high-quality digital SLR photography with little trouble or confusion.
It features an upgraded version of the PENTAX-original Auto Picture mode, which
automatically detects the type of subject or scene, and sets the proper shooting
mode for the photographer. It also features a host of advanced features and sophisticated
functions - including the innovative in-body Shake Reduction mechanism - to assist
the photographer. It also offers a compact, lightweight body, designed by incorporating
PENTAX's advanced downsizing technologies, accumulated over the years of digital
SLR development, into different body parts. As a result, the PENTAX K-m assures
simple operation and outstanding operability, even for inexperienced first-time
digital SLR users.
Along with the PENTAX K-m, PENTAX will also launch two DA L-series interchangeable zoom lenses: the smc PENTAX-DA L 18-55mmF3.5-5.6AL and the smc PENTAX-DA L 50-200mmF4-5.6ED. Designed for exclusive use with PENTAX digital SLR cameras, these DA L-series lenses are designed to be more compact and lightweight than conventional counterparts, without sacrificing any of the exceptional optical performance common to all PENTAX lenses.
The smc PENTAX-DA L 18-55mmF3.5-5.6AL and smc PENTAX-DA L 50-200mmF4-5.6ED lenses will be marketed only as a part of the PENTAX K-m Lens Kit or PENTAX K-m Double Zoom Kit.
Compact, lightweight body for enhanced portability and maneuverability
Despite the incorporation of a large-sized image sensor (23.5mm by 15.7mm),
the PENTAX K-m offers a compact, lightweight body to assure remarkable portability
and maneuverability. This was made possible by the development of a compact,
lightweight and high-rigidity stainless-steel chassis, the downsizing of
the Shake Reduction mechanism and circuit boards, the employment of latest
high-density packaging technologies assuring most efficient positioning and
layout of various parts, and the repositioning of the battery compartment.
The camera grip has also been redesigned to assure firm, comfortable hold
of the camera body.
Simplified operation system for easy camera handling
The PENTAX K-m features a newly designed control system, which positions
most of buttons and levers on the camera’s grip side, making it easier
for first-time digital SLR users stepping up from their compact models to
operate the camera. What’s more, the functions of each button or lever
are instantly displayed on the camera’s LCD monitor with a single press
of the help button to facilitate camera operation — especially for
those who are unfamiliar with digital SLR cameras.
PENTAX-original Shake Reduction mechanism for sharp, blur-free
The PENTAX K-m comes equipped with the PENTAX-developed SR (Shake Reduction)
mechanism, which effectively reduces camera shake for sharp, blur-free images
even under demanding shooting conditions — such as when using a telephoto
lens, shooting in the dark or at night without supplementary flash illumination,
or using extended exposures for sunset scenes. This innovative SR mechanism
shifts the position of the image sensor vertically and horizontally at high
speed using magnetic force, while adjusting the shifting speed in proportion
to the amount of camera shake detected by a built-in sensor. It offers an
outstanding compensation effect — up to the equivalent of approximately
four shutter steps. As a result, it does not require special anti-shake lenses,
and can be used with almost all existing PENTAX interchangeable lenses.
*** Lenses compatible with this mechanism are: the PENTAX
K-, KA-, KAF-, KAF2-, and KAF3-mount lenses; screw-mount lenses (with an
adapther); and 645- and 67-system lenses (with an adapter). Some functions
may not be applicable with certain lenses.
Comprehensive Dust Removal system with prevention, removal
and confirmation devices
The PENTAX K-m features the user-friendly DR (Dust Removal) system to prevent
dust from appearing on captured images. Applied to the CCD image sensor surface
(or low-pass filter) through the vapor deposition process of a fluorine compound,
the PENTAX-original SP (Super Protect) coating effectively removes dust and
stains from the surface. In the next step, dust that still remains on the
surface will be shaken off when the SR system shifts the image sensor at
high speed. Finally, the dust that is shaken off the image sensor will fall
onto an adhesive sheet positioned at the bottom of the SR unit, eliminating
any possibility of it returning to the image sensor surface. This DR system
even offers a Dust Alert function, which allows the user to confirm the dust-adhesion
status of the CCD in advance.
Auto Picture mode for automatic selection of optimum shooting
The PENTAX-developed Auto Picture mode is programmed to automatically select
the most appropriate shooting mode — from such choices as Portrait,
Landscape and Macro — for a given subject. With the PENTAX K-m, this
user-friendly mode is further upgraded, with automatic detection of situations
requiring the Night Scene Portrait mode. Since all camera settings, including
aperture, shutter speed, white balance, saturation, contrast and sharpness,
are automatically adjusted by the camera for optimum results, the user can
concentrate on image composition and shutter opportunity.
The PENTAX K-m combines a large, high-performance CCD image sensor (23.5mm
by 15.7mm) with the sophisticated PRIME (PENTAX Real Image Engine) as its
imaging engine. With its approximately 10.2 effective megapixels, it produces
beautiful, fine-detailed images with subtle gradations and delicate texture
description. It also features a Custom Image function, which offers a choice
of six finishing touches to help the user create intended images.
High-speed continuous shooting at approx. 3.5 frames per
The PENTAX K-m lets the user keep shooting images at the speed of approximately
3.5 frames per second (in the JPEG recording format), allowing the user to
capture a sequence of a fast-moving subject with great ease.
High-precision 5-point AF system
The PENTAX K-m incorporates a five-point wide-area AF system (SAFOX VIII
with five cross-type sensors) to assure dependable, high-precision autofocusing.
Using the five sensors positioned in a cross pattern over the image field
(one in the middle, two at sides, and two at top and bottom), this system
automatically and unfailingly selects the optimum sensor for a given subject.
It also allows the user to fix the AF detection point at the middle sensor.
Thanks to a thorough review of the AF algorithm, this AF system also offers
improved autofocusing speed under poor-lighting conditions, in which conventional
AF systems take longer to focus on the subject.
Auto sensitivity control up to ISO 3200
The PENTAX K-m’s auto sensitivity control function automatically sets
the optimum sensitivity between ISO 100 and ISO 3200, based on such data
as the subject’s brightness level and the lens’ focal length.
Since this function allows the user to take advantage of faster shutter speeds
in poor lighting situations (such as indoor sports events and nighttime scenes),
it helps the photographer to effectively reduce camera shake and subject
shake and prevent blurred images.
Effective gradation compensation
The PENTAX K-m’s dynamic-range expansion function allows the user to
expand a dynamic range (or a range of gradation reproduction) to minimize
white-washed areas in the image. On the other hand, its shadow compensation
function minimizes pitch-black areas lacking details. Combined, they help
the user to produce beautiful, rich-gradation images when shooting high-contrast
Large, easy-to-view 2.7-inch LCD monitor
The PENTAX K-m features a large 2.7-inch color LCD monitor with approximately
230,000 dots on its back panel. This monitor’s wide-view design allows
the photographer to check the on-screen image from approximately 170 degrees
both vertically and horizontally. It even offers digital zooming of playback
images up to 16 times for easy confirmation of the image’s focusing
status and details.
Bright, clear viewfinder
Thanks to a combination of a lightweight penta-mirror prism, a PENTAX-original
finder optics and the acclaimed Natural-Bright-Matte focusing screen, the
PENTAX K-m’s viewfinder delivers a large, bright subject image with
an approximately 96-percent field of view and an approximately 0.85-times
Digital filters for unique visual expressions
The PENTAX K-m’s built-in digital filters let the user effortlessly
add some creative and artistic touches to recorded images — without
the use of a PC. The user can select one of 14 different digital filters — including
the new Toy Camera and Retro filters — to create a desired visual effect.
