SAFOX 11 Autofocus ModuleSAFOX 11 Autofocus Module

Assure the sharpest focus with the SAFOX 11 autofocus module maximizes 27 AF sensors and a vast light sensitivity range of –3EV to +18EV. The new focus module includes 25 cross sensors and three AF sensors dedicated to low light focusing.

Real Time Scene Analysis with 86,000 pixel sensorReal Time Scene Analysis with 86,000 pixel sensor

The new Real Time Scene Analysis System features an 86,000 pixel RGB light-metering sensor and improved algorithms that further enhance accuracy of exposure, white balance and autofocusing. This assures a perfectly exposed image even in difficult lighting conditions.

Durable designDurable design

With a magnesium alloy body, die cast aluminum chassis, and 76 special seals, the 645Z boasts a fully weather and coldproof design to resist water, fog, snow, sand and dust, for top performance in extreme field conditions as well as in the studio.

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.

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.

Optional FLU, Eye-Fi Wireless, and SDXC Memory card compatibility

Perfect for studio or macro shooting situations, the optional 16 GB FLU CARD 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.

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.

100-204800 ISO

High sensitivity range of ISO 200-204800 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.

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 colour reproduction. With a newly added Multi-Pattern Auto mode, switching back and forth between modes is easily achieved.

HDMI port

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

HDR Image Capture

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

Customizable RAW/Fx button

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

Other features
