  • Anti Aliasing filterless design

    Anti Aliasing filterless design achieves superior resolution for rich, detailed imagery at supreme resolution where camera settings, lens selection and shooting conditions are controlled to prevent moiré.

  • Optional Flucard, Eye-Fi Wireless, and SDXC Memory card compatibility

    Perfect for studio or macro shooting situations, the optional 16 GB Flucard for PENTAX in the 645Z allows the photographer to remotely change settings such as aperture, shutter speed and ISO, shift the AF focus point, release the camera shutter, check a Liveview image, and browse and download images to any web browser enabled device. Eye-Fi Wireless and standard SDXC Memory cards are also compatible.

  • 100-204800 ISO

    High sensitivity range of ISO 100-204800 with improved noise performance throughout, including ISO-specific noise reduction, the 645Z will be ready to perform in a wide range of light levels and shooting conditions.

  • HDMI port

    An HDMI port outputs high definition images, video and sound to HDTVs.

  • Customizable RAW/Fx button

    Customizable RAW/Fx button allows for easy access to common shooting settings.

  • Beautiful, full HD movies and H.264 video

    Enhance your video recording experience with full HD movie capture in the H.264 format (1920 x 1080 pixels/60i/30p), also including the ability to switch from still image to video recording with the flip of a dedicated switch. Equipped with a stereo microphone terminal for external microphone connection, the user can also adjust the audio recording level manually and visually monitor sound levels during recording.

  • Dual SD card slots

    Dual slot SD/SDHC/SDXC 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.

  • Multi-pattern white balance

    When shooting scenes that include multiple light sources, such as sunlight and shade or flash, light sources are recognized automatically and the image is separated into different areas. White balance is adjusted separately in each area according to the different light sources to achieve optimal color reproduction. With a newly added Multi-Pattern Auto mode, switching back and forth between modes is easily achieved.

  • HDR Image Capture

    Improved in-camera HDR image capture features more blending options and better pixel registration for easier operation without a tripod.

  • Other Features

    • Compatibility with new D FA autofocus lenses as well as older 645 lenses ensures a wide selection of PENTAX glass for a wide range of photographic applications. • 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. • All-glass, trapezoid pentaprism viewfinder with interchangeable focusing screens offers a 98% field of view viewing angle for accurate framing applications. • 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. • A Digital Level function displays the vertical and horizontal inclination of the camera, ensuring captured photos remain level to the horizon.
