Both bodies carry the same 200,000-actuation rating, so shutter durability is a wash — your buying decision comes down to sensor, features and price, not shutter wear.
Rated figures are manufacturer estimates, not hard limits. Many bodies shoot well past their rating, while a small number fail earlier — the rating is best read as a durability class, not a countdown. When buying used, what matters is the actual actuation count relative to that rating, which you can read for free below.
The Z7 II is the newer design (2020 vs 2017), which usually means longer firmware support, a more current autofocus system and a stronger residual value — but also a higher used price.
Because both are Nikon bodies, your existing lenses and accessories carry straight across — the decision is purely about the body itself.
Both cameras write NEF RAW files, and ShutterCount reads the actuation count from the MakerNote of each.

Both the Nikon D850 and the Nikon Z7 II are rated for 200,000 shutter actuations, so neither has a durability edge on paper.
Take a photo, then drop the resulting NEF RAW file into shuttercount.app. The count is read from the file’s MakerNote entirely in your browser — no upload, no account.
The Z7 II is newer (2020), which tends to mean better resale value and longer support; the D850 is often the better bargain used. Always verify the actual shutter count from an original RAW file before buying.
No. Only the manufacturer’s service centre can reset the hardware counter, and only after a physical shutter replacement. EXIF editors can rewrite surrounding metadata but cannot alter the in-camera counter, which is why you should always read it from an untouched NEF/NEF RAW file.
