* Recording capacity shows approximate number of shots recorded during CIPA-compliant testing. Actual performance may vary depending on operating conditions.

  • A 40-megapixel medium format (44x33mm) CCD sensor provides a top resolution of 7264x5440 pixels, which is ideal for ultra-high resolution imaging, exceptionally large printing applications, and outstanding cropping flexibility.
  • Magnesium-alloy covers around a rigid aluminum diecast chassis adds durability and thermal stability while minimizing weight.
  • Fully weather sealed and coldproof design resists rain, snow, dust and other environmental hazards during field use, to keep the camera operating at peak performance levels.
  • Large, 3" LCD screen, with anti-reflective coating and reinforced glass surface, features 921,000 dots of resolution, wide-angle viewing and 32X image review magnification for easy on-camera image proofing.
  • Compatibility with new D FA autofocus lenses, as well as older 645 lenses, ensures a wide selection of PENTAX glass for a broad range of photographic applications.
  • Highly responsive and accurate 11-point SAFOX IX+ autofocus system features a light wavelength sensor for improved focus speed and reliability, even within different lighting environments.
  • Highly accurate 77-segment metering system for perfectly exposed images even in difficult lighting.
  • Deep, 14-Bit RAW files in PENTAX PEF and Adobe DNG formats retain great detail in highlight and shadow areas of an image, and offer a high level of flexibility when processing RAW files.
  • Dual-slot SD/SDHC memory card support ensures fast and reliable storage for high-resolution image files, simultaneously saving in multiple formats, assigning images to different cards based on their original format, or easily holding one memory card in reserve.
  • ISO 100-1600 provides great existing-light photo capture with outstanding noise performance.
  • Highly flexible white balance options include several common presets, 3 Kelvin color temperature settings, and 3 manual saves, each with WB fine adjustment tuning.
  • All-glass, trapezoid pentaprism viewfinder with interchangeable focusing screens offers a 98% field of view viewing angle for accurate framing applications.
  • Multiple JPG image processing modes include Bright, Natural, Portrait, Landscape, Vibrant, Muted, Reversal Film and Monochrome, for high-quality JPG output without extensive computer enhancement and manipulation.
  • Lens Correction function automatically compensates for lateral chromatic aberration, as well as barrel and spool distortion common to wide-angle lens photography, with select PENTAX 645 lenses.
  • Consecutive shooting up to 1.1 frames per second at full 40-megapixel resolution, enables action photography in a medium-format camera system.
  • An in-camera HDR image capture function blends 3 consecutive frames of varying exposures into a single, perfectly blended image, maximizing detail within all tonal ranges.
  • Mirror-dampening hardware applies a braking action to the mirror swing, minimizing the effect of camera shake and noise levels to the image capture process.
  • Mirror Lockup function prevents blur caused by the movement of the mirror during the exposure, ensuring the sharpest possible image capture for professional-caliber applications.
  • HDMI output for high-resolution image display on HDTVs.
  • A Digital Level function displays the vertical and horizontal inclination of the camera, ensuring captured photos remain level to the horizon.
  • High-capacity Li-Ion battery provides up to 800 shots in typical shooting conditions.

Our first medium-format digital camera is garnering flattering attention from the photography world for delivering 40-megapixel image quality at an attractive price. The PENTAX 645D's 44x33-millimeter CCD produces ultra-high resolution images ideal for even the largest of print sizes. Offering ergonomic familiarity to any PENTAX DSLR owner, the body is considered superbly balanced with a light but tough aluminum diecast chassis surrounded by magnesium alloy covers, and extensive weather sealing as well as automatic sensor-dust cleaning, a first in a medium-format digital camera.
