Bulb Exposures
If you take a picture without looking at
the viewfinder, light entering the
eyepiece can throw off the exposure. To
prevent this, slide the eyepiece shutter
lever as shown by the arrow to shutter
the eyepiece.
You need not shutter the eyepiece during
Live View shooting or movie shooting.
You can connect 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 and shoot with it.
To operate the accessory, refer to its instruction manual.

control terminal.
