The TC-80N3 Timer/Remote Controller is a programmable electronic shutter release. When you connect it to your EOS SLR or DSLR it will allow you to control:
- When the shutter opens (self-timer mode)
- How frequently the shutter opens (interval timer mode)
- How long the shutter stays open (long-exposure timer mode)
- How many exposures the camera will make in total (exposure count mode)
You can also combine modes: For example, you can program the controller to wait five minutes, release the shutter, then take a total of 25 exposures at five minute intervals. Refer to the Combinations Chart for more details.
The TC-80N3 also includes a remote switch that provides the same functions as your camera’s shutter button (auto-focus, autoexposure, and shutter release). When used simply as a remote release (no timer functions), the TC-80N3 does not require battery power.
