colinm 0 Posted June 13, 2014 Needing some help here. I've got a 7D and I'm not sure if I've messed with a setting but it has started to pre-flash a lot. The setup is the camera's own flash on manual at its minimum power, a couple of Z240s on manual, and a FIX500 as a focus light. I'm wondering if the camera's own flash being on 1st or 2nd curtain would make it more or less prone to pre-flash? All help, and suggestions most welcome.

eyu 27 Posted June 13, 2014 Is the advance canceling circuit on the Z240 on or off? Share this post Link to post Share on other sites
pbalves 52 Posted June 13, 2014 Have you the red eye reduction function activated? Share this post Link to post Share on other sites
Alex_Tattersall 90 Posted June 14, 2014 Could be the autofocus assist also. Need to switch this off. Share this post Link to post Share on other sites
colinm 0 Posted June 14, 2014 Thanks for the input guys. A few things to check out. Great hammerhead. Sorry I forgot to mention it originally. The ACC circuit is engaged. The button is pressed in. Share this post Link to post Share on other sites
