"Upgrading" decision, Pentax 645Z or Nikon D850(810)

Hello

I am always surprised by this type of reaction. If you buy an apn only for its resolution and dynamics, buy a 5DSR ...
A 645D is much better in my opinion: the surface of the sensor explains that but it takes experience to detect it. The mf offers a 3D rendering, a relief impression. The D850 is excellent but it does not offer this rendering. It would not occur to a portrait painter to compare an apsc with a FF. Apsc and ff can have the same number of pixels

I'm late to the party, but here goes my experience in owning all three.. D850, had a D810 and a 645z.
For most of my commercial work I use the 645z. If I had to sell all of my gear except one system, I would keep the 645z.
I love the files out of that camera, to me 35mm DSLR may have the same pixel count but there is still something lacking. I cannot put it into words, but it is something I clearly see.
I am not new to photography as I have been shooting commercially for 25 years. In the past most of my commercial work was done with the Pentax 67.
I have what I consider a great set of lenses, bought at very reasonable prices from shops in Japan (ebay)
28-45, 35mm, 55 2.8, 150 2.8, 120 macro, 45-80, 80-160 and my recently acquired 300 f4. All lenses are AF and most came with the camera when I bought it second hand for a great price.

Indeed, same here. I say that my Z files have a certain "suave" quality, and the FF ones seem more brittle. Certainly in post the Z files give me more room for maneuver.

The D850 is significantly cheaper and portable. The 645Z is significantly more expensive and bulkier. On the other hand, you'll get more resolution and DR from the Pentax.

The choice is yours.
