While the 645Z's AF system can't compete with a high-end small format SLRs, it is pretty impressive considering the size and weight of the elements inside the compatible lenses.

Pentax 645Z review

by Angela Nicholson |
www.techradar.com
Despite the water on the grip and covering the buttons and dials it continued to function correctly, and I was able to keep a good grip on it.
It's pretty good at ISO 204,800 as well, but there's a drop in colour saturation.

Hands on with the Pentax 645Z

www.dpreview.com
Let step back Canon in 2005 announce the first Full Frame DSLR and Nikon to this day has been trying to take the lead back-to make even more challenging Canon with out knowing the outcome with the second Full Frame with video capability that charge the game Nikon has never recovered since.
To avoid this kind of bad reviews (People would be saying "why din't Pentax put a headphone jack next to the microphone jack).
