Re: (1dx) Better to just get out of Av mode!

Selecting f/1.4 is telling the camera to select a very fast shutter speed, faster than the flash sync speed. The camera responds by shooting at the maximum flash sync speed, but the Speedlight defaults to full-nuke. This is my non-technical way of understanding Syl Arena's answer to a nearly-identical question at a Speedliter's Intensive event.

The simple, quick solution is to set either the camera or flashgun to Manual. I almost always use the camera's Manual Mode when using a Speedlite. I am not an expert, and do not claim the title of "professional" photographer, but as my signature lines indicate, I have some practical experience with Canon Speedliting.

I wear a badge and pistol, and, primarily with 7D cameras, with 10-22mm and 100mm Macro L lenses, shoot evidentiary images at night, which incorporates elements of portrait, macro, still life, landscape, architecture, PJ, and occasional action.
