Used for my Canon Mark III (now sold), but says it can be used on Canon EOS 7D 50D 40D D200 as well. Bought new for around $75 four years ago from (The Camera Store in Calgary) and is in perfect working condition. Comes with 2 free new lithium batteries which are almost the value of what I'm selling the remote for.
