The Canon off camera shoe cord 3 is around £48 in the UK, thats more than i am prepared to pay for the occasional use i will need it for, so i decided to try my old off camera shoe cord that i used on my EOS film cameras for taking some closeups with my 50D and 580ex, I set the camera to manual and the results were spot on, I presume the 580ex was working in TTL mode, is there any risk to the camera and flash using this old off camera shoe cord?
