[QUOTE="gabyte00, post: 228577, member: 18195"] No problem. The flas is firing every single time but in those underexposed pictures is firing at very small amount of power. You cand tell this by the naked eye and know that you got an underexposed one before it appears on lcd creen. The reason that I did most of my tests with the flash bounced is that if the flash head is in normal position the difference between the shots is smaller because even if the flash is firing low power you can still see it. This way that low power has no significance in the final shot. The flash is in the hotshoe on the camera. I cannot duplicate the problem using CLS and on camera flash to trigger the SB910. I also have a Pixel Pawn trigger/receiver but it's not TTL capable so it works just fine. Firing every time. I've had a D60, D3000, I've worked with D300, D700 and I never had this situation before. So for sure you cannot duplicate this on another model. That's why I asked peope with D7100 to try this and see the results. I'm trying to find out if there is an issue with a batch of D7100s or is a general thing. On our Nikon official forum here in Romania I've found at least 4 people who experienced this. As I said before, I have around 5000 shots trying to isolate the problem. I've tried many lighting situations. From groups of people in churches and restaurants to simple scenes with one object and one color backround. There is no difference, the results are the same. I to suspect a defect in the camera especially with the TTL system. I wrote Nikon Europe about this and they said to give them time until december to run some tests of their own so I'm waitng for their results. There is a discussion on flickr about this [url=http://www.flickr.com/groups/nikond7100/discuss/72157635272306708/]Flickr: Discussing Flash misfire in The Nikon D7100 Group[/url] [/QUOTE]
