I've been deciding whether to post my opinions and thoughts on the Z6 and how I acquired it...decided to do it, in case it helped anyone in their own decision. I've been with Nikon for a few years now, been a Pentax user before I started with a D7100, added the D600, traded them both for a D750 and now bought the Z6. The Z6 is my only camera at the moment...
I only have F mount lenses, no Z mount lenses at the moment. All of my lenses function well with the Z6, no complaints there.
I thought long about what would be my upgrade path and was saving up for the D850 and after seeing the announcements of the Z cameras, I was even more certain about getting the D850 But after reading more and more about the Z6 (Z7 didn't interest me due to better high ISO and better FPS from Z6) I was getting curious about it. I got the chance to use it for a weekend in a National Park nearby...and afterwards was certain it would be the right choice for me. After going back to the D750 it felt dinosaurish
A few things swayed me to purchase the Z6....the biggest being no need to AF Fine Tune
. It was great seeing all of my lenses hit the target without needing to tune them for hours. The ergonomics felt great as well. Focus points covering 90% of the sensor is another biggie that felt awesome...and it was fast.
I was a bit worrisome about AF-C though....I did get a few chances to test it over that weekend but not enough....and I was using a Nikon 200-500mm; not the fastest lens out there
I still decided to buy it; I've had it for a few weeks now and am thrilled about it. Battery life is of course worse than the D750, it only has one card slot (expensive)...but those are not deal breakers...
AF-C Section
I also managed to test AF-C a bit more...this time using the 70-200G VR2. AF-C is quite capable, different to the DSLR, but still capable. I would say it easily beats my D750 in AF-C. Not as good as the D5/D500 I'm sure, but more than capable to handle any but the toughest situations. I had the most luck with BBF, AF-C in Dynamic Area (WIDE-S works good too), H+ and AF Lock On set to 1 or 2.
Since I'm sure you want to see some proof, here's a series of 28 photos taken of my dog running full speed at me. Covering a distance of about 25 meters in 1,5 seconds. Are all the photos in perfect focus? No, but most of them are...in the end she was closer than MFD to me (last two shots). Definitely an improvement over my D750. I'm also quite confident in using this combination for such action shots.

I'm not trying to force my opinion on anyone, just wanting to help anyone in the same dilemma as me...to what do I move on from my D750?
