Right, I saw your reply, and I replied in turn that I had done some test shots that pretty clearly show (to my untrained eye, anyway) that despite the master flash being set to OFF, it was firing *at exposure time*, as shown in my photos. I get the idea clearly enough--it's pretty simple, really, and the controls to disable the master flash are quite simple too--it just doesn't seem to be working. ;(
Check out my test shots at http://groups.yahoo.com/group/elan7e/files/Alex%27s%20EF%20500%20testing/ (ouch, ugly URL there...) I can post the pics elsewhere if non-Yahoo members of the EOS list here want to see them. --Alex > > [EMAIL PROTECTED] wrote: > > Ok, not quite, but...since it seems like the Elan 7 won't allow the wireless > > ETTL master flash (in this case, an EF 500) ... > > Hi Alex, > > I answered this very question from you on the Elan 7E list, but you might > have missed it the first time around: > http://yahoogroups.com/message/elan7e/2601 > > > I think there is a very troubling flaw of logic in this thread.
