So i bought the RD-616 and RF-616 16 channel wireless trigger/receiver from ebay. Everything is working great , but i am seeing some radio interference in my photos. Both 28-70 and 17-40 exhibit this behavior. The camera is a 5d the flash is a 580ex , anyone have any input ? This only happens on the upper portion of the frame, very small area of the image.
