Hello, I need an advice from experienced users. I shoot in low light indoor and my gear is EOS 80D + EF-S 10-22. I have one Speedlite 430 ex II with broken hot shoe, but I think it is functional. I would like to use it as a slave flashlight and I have no experience shooting with flashlights. What should I choose/buy for triggering that flashlight? Is another 430 ex II as a master good option? How to pair it?. Have in mind that camera built in flash light is not an option as a trigger, when using ultra wide lens. Any advice is welcome... Thanks
