eyepiece shutter lever as shown by the 
arrow to shutter the eyepiece.
You can connect Remote Switch RS-80N3 or Timer Remote Controller

screen. This is called “Live View shooting.”

camera’s internal temperature may increase and it can degrade 
image quality. Terminate Live View shooting when not shooting 
images.
  For a long exposure, stop Live View shooting temporarily and 
wait...

a tripod for shooting still lifes, for example.
