Question about Nikon Speedlight SB-800 TTL Flash

Flash fires but picture is dark

I have the same problem. I have other flashes that work fine, but one looks to be completely out of sync with the camera. It does not matter if it is fired as the master or as remote, same results.

When I take a promaster remote flash trigger system with my canon 430ex half of the picture is exposed. What am I doing wrong?


this is most likely a sync issue. you shutter speed is too high. try lowering it. 1/200 or 1/160 of a second should be fine for your case.

I have a Canon EOS 40D camera. We are having problems with using an external flash. The pictures always come out extremely dark with the external flash. The flash seems to work fine, it flashes...


I don't know if this will help and this post is two months old. The camera store may be right that the synchronization is the issue which tends me to point a finger at the external flash. There are at least three different flash units that will flash when the picture is made but only one type will sync with the camera. A digital flash unit is different from a film flash so a Canon EX type is required to sync with Canon TTL or TTL II digital cameras. An EZ will flash but it's off a bit, so I can only assume that your Promaster and Canon flash units are for film cameras. Okay and another thing that could be throwing things off a bit is the camera may have been programed in Custom Functions to use "Second Curtain" or "Rear Curtain". Just seams to me if the built in flash works then it's the external units at fault.

How can you test a camera before use to be sure the flash sync is working properly.


Set camera up and aim at a blank wall. Place flash on camera, fire off test shots with camera set to flash sync speed and lens set to wide angle (eg 18 mm), ensure flash matches angle of lens. 
You will probably have to turn auto focus off, so that camera will fire, after taking photo/s use review to ensure that you have a nice even coloured piece of wall.
Any problems either with camera sync problems or flash coverage will show up in the test shots.
Camera sync, will show as part of the frame only exposed, for example you may find a horizontal line approximately 1/3 to 1/2 of frame with a proportion of the frame dark.
If you have flash "drop off" you will find the corners of your frame will be dark, you need to ensure that your flash angle specified on the flash and the focal length of the lens match.
Hope this helps Ian

Nikon SB 800 fires but pictures reamain dark


I have 2 SB-800s. When batteries leaked in one Nikon took forever to fix it, so they eventually sent me a refurb. Then they sent my original back. Which was great, until recently it developed this problem.

Another possibly related side effect is the modeling flash does not burst -- it only fires a single (very bright) flash.

The capacitor argument sounds likely. Coincidentally I also had a problem where the flash would fire sporadically -- but that was due to scuz buildup on the contacts.

Sorry I don't have a real solution for you.

My sb 600 fires with the camera but it seems not illuminate


Definately a settings problem. The camera will only syncronize on one specific speed. Youe best bet is to use auto. For manual, you'll have to set the shutter speed at the sync speed.

Flash Sync Speed
  • up to 1/250 X-Sync Speed
  • up to 1/8000 FP High Speed Sync
  • Red-eye reduction
    Red-eye reduction with slow sync
    Rear-curtain sync
    Slow sync
    Front-curtain sync (normal) Flash Sync Modes
  • 1) i-TTL: TTL flash control by 1,005-pixel RGB sensor, built-in flash, SB-800, SB-600, SB-400: i-TTL balanced fill-flash and standard i-TTL flash
    2) AA (Auto Aperture-type) flash: Available with SB-800 used with CPU lens
    3) Non-TTL Auto: Available with Speedlights such as SB-800, 28, 27, and 22S
    4) Range-priority manual flash; available with SB-800 Flash Control

    The flash pictures are only half exposed, like drag on shutter


    Sounds like the shutter needs repair. Either the opening curtain is sticking or the closing curtain is not holding long enough. Another problem might be the camera's sync speed might be lower than 1/125 of a second. Many cameras use 1/60th or 1/90th of a second as their flash sync speed.

    Dark pictures with flash


    I had this problem before, sent it off to have it repaired 1 year ago, and now have it again. Just to make sure it's the same problem, here's a description: The flash seems to be out of sync with the shutter. Using the flash in medium or low light (in auto mode) makes the picture darker than not using a flash at all. It ruins the picture. In a completely dark room, even though the flash fires, the pictures comes out pitch black. The problem is the flash unit -- it needs to be replaced. If your camera is under warranty, Canon will replace it for free. (You pay only to ship it to them.) (You might try what they told me to try before I shipped it off, and that was to reset the camera by pushing and holding the menu button until it resets. Didn't do anything for mine, but who knows.) If it's not under warranty, Canon will offer to replace it with a refurbished newer model for a discounted price. That's my situation now, because the problem has come back. I did come across a posting that described how to replace the flash unit yourself -- it involves taking the camera apart, but looks doable. (Sorry, I don't have the link handy and I'm not sure if I can find it back.) The problem is, I don't know where to get the part. Canon has been no help on this. Anyone know where I can get a Canon flash unit for the A85? Hope this helps, and good luck.
