I have both the Pentax 645Z and the D800E and the Pentax is just superb. The only time I have used my D800E since I got the Z was for a magazine article where the magazine insisted I shoot with the Nikon. I had the 5D3 before the nikon and lived the high ISO performance and the truly silent silent shutter (Nikons implementation of this is poor way to much sound on the quiet shutter). I gave the camera to my brother in law to borrow.
The Z performs really well at all ISOs low as well as ridiculously high. Dynamic range is more than 14 stops and I tend to ETTL rather than ETTR as you can push so much detail from the shadows it's ridiculous.
With the new canon I know people are asking for shots at wide apertures but since they are pitching this at landscape shooters like me so f/11 is far more typical for my style of shooting than f/4 or f/5.6 would ever be. So tests should be on this basis of apertures f/8 to f/16. With nikon I frequently shoot at f/11-16 and the Pentax I'm normally in f/11-16 with some forays into f/22. I don't do pixel peeping so am not nitty picky about theoretical diffraction.
The only thing that would get me back to Canon with this would be if they sort out the low ISO noise and banding and get to 14 stops of DR. I don't want to be forced to do HDR because the camera can't shoot scenes I want to. I am in the market for a possible replacement for the Nikon but may see what Sony offers by way of A7R2
Thanks for the feedback. Your impressions echo the sentiments of others who have used or owned both the D800 and the 645Z. How do you like the Pentax glass?
I can comment on the Pentax HD DA 645 28-45mm F4.5 ED AW SR Lens (shooting only lanscapes)
2. Big (some may say massive) and heavy but balances well with the body
3. Optical stabilization works very well
Paired with the 645Z it takes some very amazing sharp shots. (when I get my computer back up and running I'll post some examples).
