I guess I forgot I had to go into the Zoom button on my 430EX2&nbsp;and get flash to appear. So happy!</P> Sun, 31 Jul 2016 00:31:00 GMT straydog 2016-07-31T00:31:00Z https://community.usa.canon.com/t5/Speedlite-Flashes/Speedlite-430EX2-won-t-fire-with-90EX-on-Canon-5DM3/m-p/180875#M3090 <P>Although I had no problem last time I used this set-up, now I cannot get the 90EX (on my 5DM3) to trigger my off-camera 430EX2 flash. The 90EX does power up and send a flash when I take a picture. I do notice that on my flash function settings on my camera that the Master Flash Firing icon is shaded out. None of the batteries seem to be weak on either flash. Any help would be greatly appreciated. Thanks!</P> Sun, 31 Jul 2016 00:15:18 GMT https://community.usa.canon.com/t5/Speedlite-Flashes/Speedlite-430EX2-won-t-fire-with-90EX-on-Canon-5DM3/m-p/180875#M3090 straydog 2016-07-31T00:15:18Z https://community.usa.canon.com/t5/Speedlite-Flashes/Speedlite-430EX2-won-t-fire-with-90EX-on-Canon-5DM3/m-p/180878#M3091 <P>Aha!
