Master & Slave

I had been using a Canon 430 EX as a slave but it’s been stolen. Is it possible to trigger a Canon 580 EX if I use it as a slave and have a Canon compatible  Sunpak 4000AF in the hotshot on a Canon 6d or 5d. Basically I'm asking, will Canon Speedlights only respond to other Canon Speedlights?

Re: Master & Slave

The Sunpak 4000AF is an old film era flash. It is not compatible with Canon digital cameras or the Canon proprietary off camera flash system.
