I bought a used Nikon d7100, I googled how to set it back to factory defaults but I still have options that are not available for example the "Lock mirror up for cleaning" is not an option, it's dim and cannot be selected. How can I reset this? I have several dust spots that shows on my pictures.
Thank you
The most obvious is: ensure your battery is FULY charged. It wont lock the mirror up if its not.
