[QUOTE="WayneF, post: 650080, member: 12496"] Yes, if the DSLR flash door is open, the flash should always fire in camera A, S, P, or M mode (regardless of light level or of TTL or Manual flash mode). Holding hand in front of lens would not make any difference if the flash fires, it will fire if the door is open and the shutter triggers it. Flash door open is the Flash On or Off switch, it will never pop up in A, S, P, or M mode. You open door manually when you want flash, close it when you don't. Not firing would imply some defect (often the switch on the door, or could be the flash tube). Has it ever fired since? The flash only "fires as it thinks is needed" if in Auto or the scene modes. Meaning, bright scenes would not fire flash then. This is like a compact camera flash would work. A few scene modes (like Landscape or Sports) will never fire the flash (described there in camera manual). And Auto does have its adjacent Flash Off position to prevent its pop-up. Firing only with hand over lens implies mode must have been Auto (or Scene is Auto too), and Not mode A ? But dark should have done that too, so this seems confusing, I can't say I understand situation. Could the mode have been changed? Horoscopes suggestions are a good test. Because the mirror raises and the viewfinder goes dark during exposure, we cannot see if the flash fired or not, not without actually looking around the camera and towards the flash. [/QUOTE]
