Hi there, I experienced a problem for the first time with the SB-800. I have four of them and shoot with two D-700's - a lot of event work. I had a couple issues crop up the last two times I used this combo of gear. Two of my SB-800's seemed to have connection issues (exhibited on both D700 bodies) - symptoms: sometimes the flash would fire on it's own; and when I wiggle the SB-800, I can sometimes get the flash to fire. I understand this is stemming from a likely loose connection or short with the center pin; correct me if I'm wrong. Second, and more disconcerting, when shooting some dancing (D700 + SB-800 in camera hotshoe, then a Pocket Wizard synced to the PC port on the camera firing a remote SB-800 (set to manual 1/8 power, no Auto Standby). [Overall, I'm shooting the D700 in Manual, f8, 1/200, rear curtain sync, AF-S, single point, RAW, ISO 1600, at Continuous High, the hotshoe'd SB-800 on TTL -1.3 FV] Problem: About 3 in 50 shots both the on camera (hotshoe) SB-800 and the remote light DID NOT FIRE - I can tell by chimping and just seeing the lack of flash on my subject - and I'm wondering if this is a problem related to the loose hotshoe/loose connection to the SB. Or is this a symptom of something potentially more serious with the camera since the PC sync socket did not fire the Pocket Wizard and the remote flash? It usually occurs when I'm shooting at a pretty high FPS rate. I tried cleaning the hotshoe contacts and the SB-800 contacts with an eraser. Still get the intermittent firings and failure to fire. I'm going to keep shooting for now and see if I can isolate the problem with the two bodies and two of four flashes. Any thoughts on other ways to troubleshoot or address these issues? Otherwise, off to NPS for a diagnosis.
