Sorry about that bizarre post. Not quite awake here yet ;) What I meant to point out is that you *can* use flash coverage that's narrower than the field of view of the lens in some special instances. It's almost always OK to use flash coverage that's wider than the FOV of the lens (as long as you're sure the flash is powerful enough - remember the flash has less effective power as you spread its coverage out). -- Mark Roberts Photography and writing www.robertstech.com
