The TC-80N3 is the most advanced remote control available for any EOS camera. For remote photography it acts not only as a remote trigger to help avoid camera shake, but it can also be used to time accurately exposures from 1 second to 99 hours, 59 minutes and 59 seconds.
Who is it for?
All photographers looking to eliminate camera shake from their images will benefit from a cabled remote control. But the TC-80N3 goes much further than this but adding a multitude of functions for many various types of photography.
