f4 Assign Preview Button
The only difference is Nikon‘s default value: Here it is „preview“, the logical choice that is consistent with the name of the button and its usage in earlier Nikon models.
Tips: See the recommendations for the previous menu.
My preferred choice here is „access top item in My Menu“. Long walks through menus can be an obstacle in handling the D7000. The customized My Menu helps and this programming of the preview button gives immediate access to your most frequently used menu items without even moving the hands to the menu button.
