I was running around for the past week or so trying to find an Olympus Off Camera Shoe Cord and could not find on in stock anywhere. I was constantly being told that I had to order one and wait for it to come in. I went to one of my favorite camera stores and ask one of the salesmen there who has shot with the Olympus system for years. He told me that he uses the Canon OC-E3 Off Camera Shoe Cord 2 on his Olympus cameras because both cords almost had the very same set up. Canon has a five pin configuration that is configured like the Olympus, but the Olympus only has four pins and is missing the fifth pin that the Canon has on the bottom left corner and they both have a locking pin at the top. I tried the Canon cord on my E-M5 and it works perfect, especially since there is nothing but wires running through each Off Camera Shoe and nothing to damage either one. Has anyone else used this type of set up on their E-M5?
