<p>Fort what its worth, I have a nikon D700 and use a SB-800 flash gun.<br>
a few months ago in the middle of a shoot my flash started to strobe. Never happened before. I was using a Nikkor AFS 28-70 2.8D lens. Immediately after the flash started to flicker, my lens' auto focus feature stop working. I changed lenses and all three flash, new lens and same D700 body worked fine. Nikon repaired the lens and I've been using it since.<br>
Just last night the strobing again happened. This time I was using a Nikkor AFS 80-200 2.8D. No problem with the lens or flash or body after that strobing. I turned the flash off and started using it again then worked fine.<br>
Did my flash cause the 28-70 silent motor to go or did the lens cause the flash to strobe? are any of these problems related? I'd say it is the flash to camera compatibility.<br>
Any thoughts?</p>
