Need Help triggering 600ex-rt optically
I have a Canon mt24-ex that I like to use for macro work with my 100mm f/2.8 lens but I can't get it to trigger.
I normally use wireless on the my 600ex-rt(s) when I use multiple flashes but can't do that if I want to use the mt24-ex. It appears from manuals, web sites, etc. that I should be able to do this but so far I haven't had any success. I did change channel (using channel 4) and ID setting (to 0000).
Must be overlooking something...any help is appreciated.
