Have a problem with Slow Sync (580EX)
Tonight I was trying to do Slow Speed sync (2nd Curtain) with my 17-40 lens attached and it just wouldn't fire. I looked at the screen on the flash and it read "TTL" when normally it reads "ETTL". I coulnt get the camera or flash to do a thing.
So, for whatever reason, I took that lens off and put my 100mm Macro lens on. Same thing.
Took that lens off and put on my 50mm Prime and it worked fine (and it read "ETTL" again)
Anyone able to tell me what I might be doing wrong?
