SAFOX 11 autofocus module

SAFOX 11 autofocus assures the sharpest focus. Maximizing 27 AF sensors and a vast light sensitivity range of –3EV to +18EV, the focus module includes 25 cross sensors and three AF sensors dedicated to low-light focusing.

real-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. Get a perfectly exposed image even in difficult lighting conditions.

fully weather & coldproof design

A magnesium alloy body, die cast aluminum chassis, and 76 special seals make the 645Z fully weather and coldproof. Resist water, fog, snow, sand and dust, for top performance in extreme field conditions, or 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.

dual SD card slots & optional flu-card

Studio and macro shooters will like the optional 16 GB flu-card. It lets you remotely change settings such as aperture, shutter speed and ISO, shift the AF focus point, release the camera shutter, check a live-view image, and browse and download images to any web browser enabled device.

Dual slot SD/SDHC/SDXC memory card support ensures fast and reliable storage for high resolution files, simultaneously saving in multiple formats, assigning images to different cards based on their original format, or easily holding one memory card in reserve.
