I'm using a Flashpoint Transmitter (R2PRO) and several off camera flash heads. The transmitter works great when I test it with all the flash heads up and running. Sometimes the flash go off on the first trigger and sometimes it's on the second attempt. I have been using this system for over 2 years and it has been working flawlessly, till recently. All my camera settings are on Manual, including Auto Focus...manual. I use the transmitter to adjust the output of each flash.
I am now wondering, is there some internal functions/setting I don't know about that causes this intermittent flash problem. I'd sure like some help from the pros here.
