Canon EOS 5 - Manual (Page 124)

Remote Switch 60T3
This switch connects to the camera's 3-pin
remote control socket and allows you to take
pictures by pressing the remote switch in­
stead of the camera’s shutter button. This is
useful for situations where camera shake is
likely to occur, such as during close-up
photography or when using a super-tele­
photo lens. Combine with the Extension Cord
1000T3 (extension length: 10 meters/33
feet, sold separately) for taking pictures at a
distance from the camera.
Angle Finder B
The Angle Finder B makes viewing easier for
many scientific, copying and close-up photo­
graphy applications. A special adapter (sold
separately) is necessary for attachment to
this camera.
