Nikon D810 Shutter Count
◐ Expected to work
This camera hasn't been personally tested here yet, but it shares its metadata layout with a sibling model we have confirmed, so it's expected to work the same way.
Shutter count for the Nikon D810 is read from MakerNote tag 0x00A7 (ShutterCount) in the camera's NEF file metadata — entirely in your browser, the file is never uploaded anywhere.
Canon, Nikon, Sony and Fujifilm publish a rated shutter durability for most bodies — for the D810, that figure is approximately 200,000 actuations. This is a statistical durability rating from the manufacturer, not a hard limit — many shutters keep working well past it, and some fail earlier.
