Five years after announcing its development, and following a month-long online campaign trailing the launch, Pentax has finally unveiled its much anticipated 645D medium format digital camera. The first digital version of the company's 645 medium format camera system, it features a 40MP, 44 x 33mm CCD sensor, 921k dot 3.0" LCD and is compatible with the existing 645 system lenses. The camera will initially be available only in the Japanese market at a suggested retail price of ¥850,000 (~ US $9,400) from May 2010.
March 2010: HOYA CORPORATION PENTAX Imaging Systems Division is pleased to announce the launch of the PENTAX 645D lens-interchangeable, medium-format digital SLR camera. Thanks to the incorporation of a large image sensor, equal in performance to professional-standard digital camera backs, this high-performance model delivers super-high-resolution images with approximately 40 effective megapixels. It also offers outstanding dependability and superb operability and maneuverability to make outdoor shooting effortless and comfortable for demanding photographers.
The PENTAX 645D has been developed to provide super-high-resolution images produced by large image sensors — something previously available only on professional models — to serious landscape and outdoor photographers. It combines exceptional image quality with excellent maneuverability and outstanding reliability to simplify professional-level outdoor shooting. Thanks to the incorporation of a large, high-performance image sensor (measuring 44mm by 33mm) and PENTAXoriginal image-processing technology, it produces extra-sharp, super-high-resolution images with approximately 40 effective megapixels. It features remarkable durability and dependability, thanks to its lightweight but solidly built body featuring a magnesium-steel-alloy frame, reinforced glass LCD panel protectors and a reliable dustproof, weather-resistant construction. In addition, it is designed to be compatible with the majority of the existing PENTAX 645 system, so that current PENTAX 645-series camera users can take advantage of their valuable assets, including high-performance smc PENTAX 645 interchangeable lenses.
Unprecedented image quality
Solid, maneuverable body
The PENTAX 645D’s main frame is made of lightweight but strong magnesiumsteel alloy, while the chassis is made of diecast aluminum to minimize the expansion and extension caused by heat and also to optimize kinematic accuracy and thermal stability. The LCD panels — one on the camera’s top panel, another on the back panel — are covered with tempered glass plates for extra protection. The PENTAX 645D’s body is also designed to be a compact and highly maneuverable mediumformat camera, despite the incorporation of such dependable features as a dust-proof, weather-resistant construction with 70 special seals, outstanding cold-resistant performance to assure solid operation at a temperature as low as –10°C, and a newly designed shutter unit with a top shutter speed of 1/4000 second that can withstand as many as 50,000 shutter releases.
Dual SD/SDHC memory card slots
The PENTAX 645D has a pair of memory card slots for the recording of images on both SD and SDHC memory cards. This dual-slot design gives the photographer extra data-storage options: for instance, recorded images can be assigned to different cards according to recording format (such as RAW or JPEG), or one of the cards can be used as the backup of the other. The settings for each memory card slot can be easily made by dedicated button.
Dependable DR II mechanism to minimize dust spots
The PENTAX 645D comes equipped with the highly dependable DR (Dust Removal) II mechanism, which effectively minimizes annoying dust spots on recorded images, even when the lenses are changed in dust-prone outdoor settings. By shifting UV/IR-cut filters placed in front of the CCD image sensor at supersonic speed using a piezoelectric element, this mechanism effectively and efficiently shakes dust off the image sensor. Thanks to the user-friendly dust-alert system, the photographer can check at a quick glance for dust adhering to the image sensor prior to the actual shooting.
Newly designed, high-precision 11-point wide-frame AF sensor
The PENTAX 645D’s new SAFOX IX + wide-frame autofocus system features 11 sensor points (with nine cross-type sensors positioned in the middle) to assure the extra-high-precision focusing demanded of medium-format digital SLR cameras. To develop this sophisticated AF system, the entire optical system was redesigned, at the same time with the addition of the new functionality to analyze and make use of the light sources data in the field of view.
Advanced 77-segment multi-pattern metering
The PENTAX 645D employs a state-of-the-art, 77-segment multi-pattern metering system to assure super-high-accuracy light metering. The exposure accuracy is further enhanced by collecting such additional data as image orientation (horizontal or vertical) and the distance to and magnification of the subject using the sensors installed inside the camera body, with the obtained data incorporated into exposure calculations.
Large, easy-to-see optical viewfinder
Incorporated in the PENTAX 645D’s finder unit, a trapezoid-shaped glass prism not only assures an approximately 98% field of view, but also greatly contributes to the downsizing of the camera body. Coupled with a bright, easy-to-focus Natural- Bright-Matte focusing screen, the PENTAX 645D’s viewfinder offers a large, clear view of the subject.
Custom Image function to create desired visual effects with ease
The PENTAX 645D’s Custom Image function lets the user easily control an image’s finishing touches to more precisely reflect the user’s creative intentions, or to more faithfully reproduce the ambience of the scene. The user can select one of eight modes, including the new Reversal Film mode designed to create images with the colors that are typical of reversal film. In addition, all parameters — such as saturation, hue, contrast, sharpness, key, and highlight/shadow contrast — can be easily adjusted to desired levels, so that the photographer can shoot images with great ease.
Versatile, multi-mode exposure system for faithful reproduction of creative intentions
Large, easy-to-view 3.0-inch LCD monitor with approximately 921,000 dots
Positioned on the camera’s back panel, a large 3.0-inch color LCD monitor with approximately 921,000 dots provides a clear, bright view of onscreen images and menus. Since its wide-view design allows quick, effortless confirmation of the monitor image from approximately 170 degrees both horizontally and vertically, the photographer has little difficulty shooting images from low and high angles. The LCD monitor is also treated with exclusive AR (Anti-Reflection) coating to minimize reflections on the screen, even in the outdoor locations under bright sunshine.
Long battery life
The PENTAX 645D is powered by a large-capacity, rechargeable lithium-ion battery, which can capture approximately 800 images* when fully charged.
