digidurst Posted December 20, 2004 Share Posted December 20, 2004 Hi all! I was trying a little experiment yesterday with my Canon 20D and my Sigma EF-500 DG Super Flash. I used the custom function setting for 2nd curtain sync but the flash kept firing at '1st curtain sync' (for lack of a better description). Can someone tell me what I'm doing wrong? Thanks!!

ellis_vener_photography Posted December 20, 2004 Share Posted December 20, 2004 It is quite likely that the camera and flash aren't fully communicating as you aren't using Canon flash and Sigma may not have had a chance or been able to reverse engineer everything with how the Canon system works, especially with a relatively new camera like the 20D. Canon bodies can be quite touchy with how they handle second party flashes. Link to comment Share on other sites More sharing options...
beauh44 Posted December 20, 2004 Share Posted December 20, 2004 Hi Ellen, Ellis is quite correct that sometimes, Canon and Sigma don't quite get along. However, with the Canon 550EX I can set second curtain synch on the flash, or I can set it in the body itself. (Not all Canon bodies support it, so I guess they put the option in the flash itself) Does the Sigma also? If so, you might try that route. Good luck!

paul - Posted December 20, 2004 Share Posted December 20, 2004 Have you set the flash itself for 2nd curtain sync? I forget how, as it has been a while since I had the Sigma, but there is a setting for it. Setting 2nd curtain sync on the flash should even override the body's CF.

phil vaughan - yorkshire u Posted December 20, 2004 Share Posted December 20, 2004 There's an issue with the 550ex, when you set 2nd curtain, you have to do it on the flash NOT the camera. Setting it on the camera just confuses it and stops it working as expected. If that doesn't work, try setting the flash back to normal and setting it on the camera.

digidurst Posted December 20, 2004 Author Share Posted December 20, 2004 Thanks for the input everyone. But I have to admit, I'm a little irritated with Canon... What's the point of having that custom setting if the flash (Canon or other brand) doesn't respond to it appropriately?? I'll have to check the Sigma's manual - I think it does have an option for rear curtain sync but I'll be darned if I know how to set it for that.

digidurst Posted December 20, 2004 Author Share Posted December 20, 2004 Oops - I just reminded myself of another question! What if I wanted to set my Alien Bees for rear curtain sync? Is that possible? Anybody tried it? Thanks again :-) Link to comment Share on other sites More sharing options...
jimstrutz Posted December 21, 2004 Share Posted December 21, 2004 The reason for the second curtain control on the camera is for EX series flash units that don't have second curtain sync controls them selves. But I believe that on flash units that have those controls, the setting on flash is the one used. No, there is no way to set your Alien Bees for second curtain sync. Canon's second curtain sync system only works with dedicated flash units. Link to comment Share on other sites More sharing options...
