5D3 Second Curtain Sync - Design Flaw?

[Mike6158]

Old post I know but I'm about to do a shoot with the 5DMKIII and 4 or 5 strobes in remote locations and I couldn't find the second curtain synch custom function. It looks like the answer is that there isn't one, it's in the menu system, and once it's set with the speedlight mounted the setting remains on 2nd curtain synch.

There are a bunch of threads about this scattered throughout the net. Most of them have a few "never used it, don't need it" comments. I've never tried it. I can see where it would be handy and I hope that it works for me upcoming setup. I got the idea from a Joe McNally video. 2nd curtain synch is his default setting. If it's good enough for him I suppose it'll do for me.

And yes- it's a design flaw...

Now, I just confirmed that if I attach the flash, set the shutter synch, then dismount the flash and hook it up to my Cyber Sync trigger, the second curtain sync that was previously set will work as expected.

I'm not sure why but this is not the case with my 5DMKIII and Pocket Wizards. Once I pulled the 650EX-RT off camera it returns to first curtain synch.
