I have a Canon Off Camera Shoe Cord 2 for sale. My understanding is that this works with any canon flash including the most recent and the only difference between this model and the most recent is that the most recent model is more weather resistant like the Speedlight 580EXII. This cable will give you full TTL features with your canon flash and canon speedlight. The features will be the same as if your flash were attached to the camera directly on the hot shoe. It is in great condition. There are a few marks on the top, it must have been knocked about in the bag a little, but that is it. It includes the original box and manual, for what it is worth. Asking $25 shipped to the US, shipping will be additional elsewhere.
