Using The Eyepiece Shutter; F Using A Remote Switch - Canon EOS-1D X Instruction Manual

Using the Eyepiece Shutter

You need not shutter the eyepiece during Live View shooting or movie
shooting.

F Using a Remote Switch

You can connect the Remote Switch RS-80N3 or Timer Remote
Controller TC-80N3 (both sold separately) or any EOS accessory
equipped with an N3-type terminal to the camera for shooting (p.369).
To operate the accessory, refer to its instruction manual.
If you use the self-timer or bulb and take
a picture without looking through the
viewfinder, stray light entering the
eyepiece can throw off the exposure and
result in a dark picture. To prevent this,
slide the eyepiece shutter lever as
shown by the arrow to shutter the
eyepiece.
Open the terminal cover.
