Question about Nikon Speedlight SB-800 TTL Flash
I shot a wedding last week... all of a sudden, in the middle of the ring exchange, I noticed my images had no exposure - my display was showing me an almost black image. I wanted to panic. What did I do wrong? I was in manual mode, and my D300 was not indicating an F/stop on the top display. I quickly checked everything but could not find anything wrong. I powered off/on camera & nothing. I then dismounted the SB800 & things went back to normal. Hmm...
I was using a Quantum Turbo Battery power pack for the SB-800. Can this have anything to do with this problem? Today I looked at the image info of several images I took with & w/out the power pack. W/out the power pack the data appears normal & images taken w/the battery pack show abnormal settings, to include, Focal Length 0 mm, and F-Number F/0. I was also using a Tamron 17-50mm F/2.8 XR Di II LD Aspherical (IF) lens. (Can't afford the Nikon version, yet).
Image info on shots that turned out ok, using the power pack & the 17-50mm also showed some strange stuff; Focal length: 5mm, F-Number: F/95. Is this normal? Is my lens giving it incorrect data? The flash did fire each time I pressed the shutter release. I didn't even notice a sync problem, although one would think so. Help! What am I doing wrong? or is this equipment incompatability?
Thats is odd.
When you hook everything up, do you turn on the flash last?
It sounds like the battery pack is giving the flash a different voltage then it should have causing incorrect readings and exposures.
I would send the pack back to Quantum(located in Ronkonkoma, NY) and have them check it.
