[QUOTE="WayneF, post: 229415, member: 12496"] I don't know why it won't work, but I keep thinking there must be a little more to it. Did it ever work before (this TTL flash with DX2?). It should work, it should be compatible. I was thinking maybe it just was not seated deeply in the shoe, but the fact that the settings show up on it implies the CLS hot shoe communication is working OK. Maybe we should ask what does "will not work" mean? What does it actually do? What does it not do? Just does not flash? Or it flashes, but it does not light the scene in the photo? The camera meters the scene by causing a TTL preflash from the flash. It meters the preflash, and decides a proper flash power level for the final exposure. It programs this level in the flash, and then opens the shutter and triggers the flash. The basic difference in Manual and TTL modes is this hot shoe communication. Does this TTL preflash occur (do you see any flash occur?) The one imaginable easy mistake that I can imagine is if you are trying FP flash mode, since this flash cannot do it. Make sure your shutter speed does not exceed 1/250 second with the flash. Camera menu E1 should NOT be in one of the Auto FP modes with this flash, because this flash cannot do that. [/QUOTE]
