Same AF Fine-Tune as in the D5. Actually, the two cameras D5+D500 is very similar concept as the D3+D300 in their day. Nikon has put a lot of efforts in making the camera layout as similar as possible. Same goes for specifications in terms of ISO etc. The rated ISO range is just 1 EV lower than the new King of Darkness, D5.
Nikon Nordic did not have any knowledge of the camera until just a week ago, so no wonder the world was taken by surprise !! Nikon Nordic CEO declared this is indeed representing the "D400" so much asked and longer for among the Nikon aficionados.
