According to reports on Nikon Rumors, Nikon is reported working on the potential for, amongst other things, a 60MP Nikon Z8 that’d inclue “two CFExpress cards, improved VR”, and a pixel-shift mode. As they point out, this would seem to dovetail with the earlier reports that Nikon had previously entered into an agreement with Sony to purchase Sony’s new 60MP sensor.
The incredibly high-resolution sensors that we’re starting to see across the market are very exciting especially for travel photographers who are interested in everything from street photography to portraits, landscapes, and wildlife photography, the flexibility they provide is fantastic. They’re obviously great when you want to eek every bit of resolution out across the full breadth of an image that you can, say for landscapes. At the same time, the high-resolution gives you the flexibility when shooting wildlife to crop in after the fact, just as though you’d been shooting with a crop-frame body in the field. And, yet, when you do need superb noise performance in low-light conditions, you can have that, too, by comparably reducing the full-frame resolution in post. This offers nearly the same noise performance you’d get if you were shooting a lower resolution full-frame camera in the field. High-resolution sensors, thus, allow you to shoot under a wide variety of conditions with relatively few trade-offs.
The potential addition of a second card slot would likely bring a few welcome sighs of relief given the amount of controversy the single card slot on the Z6 and Z7 caused. It will also be interesting to see whether the autofocus system sees any significant update. For a mirrorless body to be a full solution for many Nikon shooters, the speed and reliability of the autofocus system will most likely have to come a lot closer to the performance of the D810 or D850’s system. Unless the Z8 also sees significant improvements there, It’d be safer keeping the DSLR handy for a while.
