Apparently my flash is fine for a few shots and then it gives me shot where is clearly under exposing. This only happens in TTL. Not in Aperture mode, neither in Manual mode. I tried to clean the contacts and I went to my camera shop and the tech went back an forth, we try different bodies and lenses and try to replicate the problem.

 

Certainly is not the camera, it's the flash. No idea.  

I have another flash same sb-910 and the screen cracked after I dropped.  So I sent it to Nikon and I'm waiting on parts for a Screen.

So I was wondering if someone has the same problem.

 

I might rent a couple of flashes to shoot several sessions I have coming.

But this sucks.  

 

I tried wireless mode, set the commander mode on my camera to ttl and it seems the sb910 is responding.  I put it on my hotshoe and here we go again with underexposing and clearly not metering properly.

 

Oh well, I guess I have no choice but to send it to NIkon and grab your ankles, not because of the price but because they are not selling parts anymore to small repair shops.

 

and guess what?.... really 3 weeks to wait to get a simple LCD fixed?

 

Anyone with the same experience?

Any chance that its an issue with the contacts between the shoe and flash that might be causing inconsistant communication?

Yes, as above. Does the flash wiggle side to side even just a tiny bit when tight on the shoe? Try rotating it like a clock while it's tight to see if there's any play.

Thank you guys, for a while I thought the problem as the wiggle, but pretty much after doing test shots under same conditions I was able to send them to NIkon and they told me I have a problem with my TTL thank god it's still under warranty.  Thank you for the replies.

Interesting, I am having the same issue with my SB910. I think I will send mine in as well.

Wow, have others had this issue?  Do you think it is across the board for the 910s?

I plan on taking a lot of portrait shots with these flashes at home to practise and develope portrait photography, so I will put them to the test and will let you know If I have any issues. Also the majority of use will be with wireless pocket wizards.

I feel a little noobie here. Theres nothing wrong with the SB910 flashes, it was with me. I did not know that my pocketWizard's had antennas. It was a hit and miss situation sometimes when firing the flashes, and I did not know that it had to do with a connection issue and when My flashes were to far from the main trigger without the antennas being exerted there was a wireless connecting problem that I finally realized. I noticed this when I moved the umbrellas back away from the camera tonight and the flashes did not fire, I then looked at the Wizards more closely and noticed they had antennas.

Notice the first picture with the antenna inserted and how stealthy it looks, no wonder I didn't notice and I guess I should have read the manuals after buying the wizards. lol

Sitting down with new equipment and the manual(s) is always a good idea...
