Nikon Rumors has recently reported on the potential for, among other things, a 60MP Nikon Z8 with “two CFExpress cards, improved VR”, and a pixel-shift mode. As they point out, this would seem to dovetail with their earlier reporting 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. As a travel photographer 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 (that’s not to say that there aren’t any, obviously; or that they aren't critically important for some photographers).
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. I took the Z7 (with version 1.0 of the firmware) to a friend’s wedding and tried to get a few shots in during the reception. Even under modestly decent lighting conditions it yielded relatively few keepers. For a mirrorless body to be a full solution for many Nikon shooters the speed and reliability of the autofocus system will likely have to come a lot closer to the performance of the D810 or D850’s 3D Focus Tracking system. Unless the Z8 also sees significant improvements there, I'll be keeping the DSLR handy for a while.
