Hi guys, quick bit of advice needed...
I just brought a second hand 580EX. I was testing it out last night and all seemed well, until I tried setting 2nd curtain sync. Normally to get this, you press the high speed sync button twice, and get the symbol showing 3 little arrows. However, when I pressed the button the first time the high speed sync symbol came up (OK) but then when pressed the second time it just reverted back to normal and didn't move onto 2nd curtain sync... Is it me or the flash? I've tried it on camera, off camera, in manual, ETTL, bounce, straight ahead, everything! I also tried settign it in camera on my 40D, but the 2nd curtain sync option is greyed out, along with the FEB option, so no joy there...
So...
1) Someone please tell me I'm doing something wrong, and the flash isn't broken and,
2) Can someone please tell me why some of the in-camera flash controls are greyed out when both my 580EX and 430EX are attached to the camera and switched on? Do I need a firmware upgrade or something?
Cheers
Jez
not sure. As I said, I've gone into the camera menu, found the external flash control bit, but then the option referring to 1st & 2nd curtain sync is greyed out. Is this what you mean, or is it a separate custom function I need to set? If so I haven't checked that yet...
