Hello. I have two questions for you guys but I didn't want to create two threads. First question. I have a Nikon D7100 and I can't for the life of me figure out how to activate the focus confirmation beep. I've been to the custom settings under D1 and the beep is activated and the volume is on high. Second question. How do I restore my D7100 to the state it was when it came out of the box as new. Thinking I knew what I was doing I have messed with some settings that I think I shouldn't have. So I want to start over with all of the settings. Thanks in advanced!
