I've tried setting it on camera and on the flash istself and I can't get it to work. The flash fires at the opening of the shutter and doesn't fire for the 2nd curtain.

So, you won't be able to use 2nd curtain sync with the 430EX off camera and triggered by an RF remote unit. ...Leo

I have the same cord, and yes it is fully ETTL compatible. No, I wasn't doubting the cord because it's a Chinese copy. Even Canon sells TTL cords which are not compatible with ETTL flashes. I was just implying that as long as the cord was not a copy of that non-ETTL compatible cord, then it should work. ...Leo

Nov 16, 2008 12:57 | #8 Thanks msowsun. Just one question, are there any downsides to having a cord on the flash? I was planning to use the wireless setup for nightclub photography but I'd really like the option of having 2nd curtain.

Set the 1D to 2nd sync and it always flashes in curtain open...never close. What am I doing wrong? (Sorry about the hijack of the thread) Had the same question for a while. Greg

There is no downside to using a cord other than having to watch you don't snag the cord on something or trip over it. You can also have the cord lengthened, or do it yourself. https://photography-on-the.net/forum/showthread.php?t=123662 Mike Sowsun / SL1 / 80D / EF-S 24mm STM / EF-S 10-18mm STM / EF-S 18-55mm STM / EF-S 15-85mm USM / EF-S 55-250mm STM / 5D3 / Samyang 14mm 2.8 / EF 40mm 2.8 STM / EF 50mm 1.4 USM / EF 100mm 2.0 USM / EF 100mm 2.8 USM Macro / EF 24-105mm IS / EF 70-200mm 2.8L IS Mk II / EF 100-400 II / EF 1.4x II

(Sorry about the hijack of the thread) Had the same question for a while. G The 2nd curtain sync option on the camera is really next to useless because it only works with those flashes that do not have the 2nd curtain sync available on the flash itself, like the 420EX. Most of the EX flashes starting with the 430EX and up have the 2nd curtain sync available on the flash so it needs to be set there and not on the camera. ...Leo

ifixsharp Senior Member 300 posts Likes: 3 Joined Dec 2006 More info | Thank you. I guess I will have to look into where that is located. I don't use flash much. I mostly do aviation photography. I know that flash has more bells and whistles than I will ever use... Greg

G On the 580EX, it's the second button from the right. it's the button that has an icon of a lightning next to the letter "H" and what looks like three arrow heads pointed to the right. Press that button and it'll cycle between high speed sync and 2nd curtain sync as indicated by the same icons displayed on the LCD screen. Just make sure that the flash is in normal operating mode instead of Master or Slave mode since 2nd curtain sync doesn't work in wireless remote mode. ...Leo

The extra foot of lenght (compared to Canon's) seems appealing.
