[QUOTE="naruse, post: 742097, member: 48632"] I think I may have discovered the reason for the flash not firing and it's embarrassingly simple; certainly not technical. Today I noticed that occasionally the peak of my cap was touching the flash. The spring loading is very light and after some careful checking of the flash ready display, I found that I only needed to depress the flash unit by about 1mm to turn it off. It's possible that when the flash didn't fire, my cap was moving the flash just enough for it to lose contact and switch itself off. Certainly for today's short session, after turning my cap around the flash fired when expected. When I got home I checked the EXIF of the files where it did not fire and they showed the flash was turned off. [/QUOTE]
