Hey guys.. I have been using the 600 speedlites off camera for a while now and I used the on camera 600 to trigger the remote speedlites..
Recently purchased the ST E3 RT transmittor and using it on my Mark III. Took it out in the field ysterday and it doesn't seem to fire the flash consistently.. there are more misses than fires.. although the green sync light is on, the flash will fire probably 1 out of 5 times.. what I have also noticed is that if I point the camera to the directlion opposite of my subject, the flash fires consistently.. like WTF!? lol
I finally gave up as I was in the middle of an engagement shoot, so I reverted back by putting a 600 speedlite on body and using it as Master to fire the slave 600 and that works like a charm, as always..
Has anyone had this issue? is there something I am missing? any firmware upgrade etc?
