It is what it is. I tried, and I know Adrenalin and I tried our hardest.

Anyways, just to put case in point, my first wedding "I shot" (I say that because I was just a guest and wanted to play around, yes, I was that "Uncle Bob" haha) I had my old D50, Sb-24 that didn't quite work on the hot shoe, and a 50 1.8:

Actually these that I uploaded had no flash...It's all the rows except the last row.

So it's of course do-able with a very minimal investment.
