Can a FTD 4000 flash be attached to a Canon?
You need to tell us the model of Canon camera you have. The Promaster FTD 4000 may or may not fire fron your camera’s hot shoe. If it doesn’t, then your camera must have a PC (Prontor-Compur) connection to plug in the flash sync cord. If you’re using a Canon DSLR then I suggest one of the Canon flash units like the Speedlite 430EX II which will be 100% compatible with your camera.
