Canon 1157C001 Remote Controller Adapter RA-E3

The Canon Remote Controller Adapter RA-E3 is a small, single-purpose accessory that bridges the gap between Canon's TC-80N3 Timer Remote Controller and camera bodies equipped with an E3-type remote release terminal. The TC-80N3 is one of Canon's most capable wired remotes, offering programmable interval timing, long exposure control, delayed shutter release, and exposure count settings — but it ships with an N3-type connector that doesn't fit every Canon body. The RA-E3 solves this by converting the connection, giving E3-port cameras full access to the TC-80N3's feature set.

The adapter itself is compact and passive, requiring no batteries or setup. You simply plug the TC-80N3 into one end and the camera's E3 port into the other. While the RA-E3 serves a very specific purpose and offers no standalone functionality, it is the official Canon solution for this compatibility issue, ensuring reliable communication between the remote and camera. Photographers doing time-lapse work, astrophotography, or any shooting that demands precise long-exposure control will find it an essential link in the chain.
