D7000 Pop-Up Flash not firing! Help?

[PatrickCheung]

I was shooting outside today, using the pop up flash in commander mode. It took about 3 shots, fully working. On the 4th shot, my SB-900 made the "did not fire properly" whining sound. I checked the camera, everything looked good. The pop up flash was in commander mode, set so that it doesnt contribute to the exposure, it was set on the right channel... everything was fine. I did about 10 test shots, putting the pop up flash in commander mode, ttl mode, manual mode and repeating mode... nothing triggered the flash.

Right before the flash died, my camera was set at ISO100, f2, 1/400, manual mode. Battery was at half full, the top display showed the flash as being up. When I put the camera in auto mode and low light, the flash pops up, shutter speed goes no lower than 1/60 (as it would if the flash was working), but no flash fires. It was about -4degrees celsius outside.

I've tried re-installing the battery, resetting my settings, turning the camera on and off. I did a quick google search, but nothing came up.

The camera didnt fall, it just sat on the tripod and stopped working

Anyone know what's going on?

Since you were shooting outside the IR from the pop up wasn't strong enough to out power the IR from the Sun, and the SB-900 couln't see the Commander mode signal from the camera. Clouds don't block IR.

It's one of the downsides to using an IR communication system.

I've driven through Markham many times while plying the 401.

I think he means the pop up flash doesn't even fire now.

Yeah, the flash doesnt fire at all! The IR system usually works all the time for me!

Markham is an odd place :]

Hi all, does anyone know if this problem has a solution yet? I am having the exact same problem with my d7000, my d90 is set up the same and it works fine. But the 7000 with the same settings does nothing!
