"D90 Pop-up Flash not working correctly"


Corona, US
          

Hi all,

I think my D90 pop-up flash is not working properly, and I will need to send it out for repair. I'm posting the symptoms just in case someone else has run into the same issue and has some insight.

The camera is under 2 years old, and has taken less than 5,000 shots. I have two batteries that are both in good condition.

I have an SB-600 that is about 5 years old, and I have used lightly. The batteries for the SB-600 are fairly new; I'm getting quick recycle times.

When I take a picture using the pop-up flash, it is overexposed by 4 stops.

I have my AE-L/AF-L button set to Flash Value (FV) lock. If I use the FV Lock, it fires the exposure flash and locks. The exposure is then at least 5 or 6 stops overexposed. If I undo and redo FV Lock, the exposure is OK.

I put the D90 and SB-600 in commander mode. I verified the group and channel settings match. The D90 does fire the pop-up, but the SB-600 won't fire.

While in commander mode, the pop-up will not contribute to the exposure regardless of how I set the internal flash mode and compensation. FV lock has no effect.

When I put the SB-600 on the hot-shoe, everything is working as it should.

I reset SB-600 and did both the "two button" and the "Reset Custom Settings" from the menu on the D90 to no avail.

So, that's my saga. I'm hoping someone will let me know the secret menu option to fix this. (Not holding my breath. )

TIA,
jim

Have you tried a camera reset?

What are the settings for the SB-600:
Mode?
Group?
Channel?

What are the Group settings on the camera for:
Channel?
Group A?
Group B?

Can you post sample images with the full Exif data?

Hi George,
Yes, I reset the D90 first using the two-button reset, then the full reset from the menu. I also reset the SB-600.

Settings for both:
Mode TTL
Group A
Channel 3

And I tried different groups and channels, making sure they matched, and the result is the same.

The examples below were shot in program mode, matrix metering, with no exposure compensation or flash compensation.

I tried manual, aperture priority, shutter priority, and full auto with no difference. And just for fun, I tried with two other lenses.

Here's a shot with the SB-600 connected to the hot shoe:


Here's a shot with the pop-up:

Hi,

I was looking at the exif data and noticed when using the SB600 your ISO is 200 and F4.O against ISO 400 and F2.8 when using the pop up flash would that make so much of a difference in images.

all the best

Hi Jim,

It definitely looks like there is something wrong with the pop-up flash.

However, in looking at the exif data, I see one thing that you are doing wrong. You should always use spot metering when using the pop-up flash when you want the flash to be primary. If you use matrix metering, it forces the pop-up into TTL-BL mode, and then you will usually get underexposure. Same with the SB-600, except, you switch it to regular TTL on the flash itself.

So, you know the problem exists in TTL-BL mode with the pop-up.

You should now try the same shot using the pop-up in regular TTL mode as follows: camera in Manual mode, Spot metering, ISO 400, 1/160th, and f/4.5.

If the problem shows up in regular TTL mode, it is almost certainly going to need a trip to the shop.

Well, I tried full manual as noted above, and it looks like a trip to the shop is in my future.

Thanks all for your help.





edit:
Don't know why thumbnail not showing up. Oh well, it looks like the bad shot above.
