Nikon made at least four Printing Nikkors, of which I have only three of them, the PN 95mm, PN 105mm, and PN 150mm. There is a PN 75mm, but I have never seen it or seen it for sale.
Of the three I have, they are not just larger (or smaller) versions of each other. They differ in terms of what you can do with them. For example, the PN 150 is sharp at the reproduction ratio of 1:1, while the PN 95 is geared more toward the lower reproduction ratios of 0.5 and so on.
One trait they all share is a restricted range of use if we want them at their peak quality. As mentioned, those qualities vary from lens to lens.
In the case of the PN 95mm lens, it is very sharp and has high resolution and that is true for both center and corners of the image. And chromatic aberration is minimal across the entire f/stop range. The PN 95 is VERY sharp at lower magnifications like 0.5 and 0.75, but it falls off at 1:1, unless you reverse-mount it, where it becomes very sharp again around 2:0. It is similar with resolution, very good at lower magnification, but not at 1:1 or above, unless reversed. Corner performance is good at 0.5 magnification, but drops off very rapidly.
So, for the kind of close-up work I do, the PN 95 is the Printing Nikkor to choose over the PN 105 or PN 150. This analysis was made possible by using the very useful lens testing results at CoinImaging.com, and I include the link:

I have noticed with the D850 that the color is remarkably different that the previous model, the D810. Not sure how to describe it, other than it seems to demand less color adjustment in post than the D810. In general, the D850 is an incredible camera, especially for the money. And although, I liked the color in the Hasselblad X1D, all things considered (especially lenses), the D850 is (for me!) a better bet than either the Hasselblad X1D or the Fuji GFX, both of which I bought, tried, and returned.
