hi, I've notice this issue with both my 2 canon 5d mark II and the CTS+CSRB: if I set my exposure to 10 seconds or more (flash on 1st curtain) the flash pops every 7-8 seconds after the very first pop. This doesn't occur with my fuji camera and the cybersync, neither with my 5ds and the elinchrom trigger. Anyone knows why?! Thank you. nico |

This is a by-product of the programming in the CST, which will fire once every 9s if the flash circuit is held closed. I am actually surprised that when used with the Fuji this does not happen. Our engineering staff is aware of this, and are looking into making changes to eliminate this behavior. |

Thank you for the answer. Greetings. nico PS: I've tried again with my fuji x100, and all is working fine... even in bulb mode (2 min. exposure) |
