Question about Nikon D200 Body Only Digital Camera

1 Answer

Exposure button not working

This maybe a repeat message before I signed up for premium advise service. I have a Nikon D200 ( for a couple of year) While shooting a football game I filled up my memory card so I changed it with another 4 gig Ultra SanDisk memory card. Suddenly I could no longer shoot exposures. and if I tried to look at the card the screen read "This card cannot be used" and there were the letters CHA flashing on the control panel. I tried formatting the card, which worked, but the problem was still there. I changed the card again, and again, and again. I replaced the battery twice. I reverted custom setting back to factory defaults and then checked every button, knob and lever to be sure there wasn't anything "between" settings. I also changed lens twice. I have about 8 scandisk cards, all 1, 2, or 4 gig. I've been using these for years. They were all empty and ready to use. I have five Nikon batteries for the D200 and they are all charged and read full when you put the battery in the camers. I could find any listing in the manual for these letters (CHA) or for this problem.

Have you done the firmware update? If not the update is available here: CLICK HERE FOR MACINTOSH or CLICK HERE FOR PC.

If that didn't solve your issue, you may have to go to an authorized Nikon dealer to have the camera reset. The internal battery cannot be serviced by untrained persons. I would also suggest that going forward, you carry your camera inside your coat when you're outside in cold weather, since electronics are easily damaged (especially software) by frost and / or water vapor which can very easily damage parts of your camera (hardware and software) in any weather.

    I forgot to mention that I've had digital cameras damaged by trying to take photos too soon after going outside from an air-conditioned hotel room into a hot humid (read beach) climate. =)

My sigma 24-70mm f2.8 doesnot work on my d7000

Could you be a little more specific about "does not work"? Does the lens not fit? Can you not view through the lens when it's attached? Does it not autofocus? Does it not meter the exposure properly?

Exposure button no longer working.

When you insert the card and get the CHA Flashing error, remove the card and format it. Reinsert it again.
Should work.

Also, if it doesn't work, there is a strong possibility there's a broken or bent pin in the memory card section of your camera. Just look closely and inspect that section to see if there's a broken or a bent pin.
This happens when you forcibly insert the card the wrong way. This has happened to a lot of users.

Did you check the exposure compensation setting? The button is on the top right of your camera and is labeled with a "+/-" symbol. Press the button and use the main command dial to zero the setting.

Does your lens have a diafragm ring? Set this one to the maximum, for instance 22. Maybe this will solve your problem.

Using 200-500 Tamron on Nikon d300. When I shoot, camera freezes. Clock and exposure readout next to it, on top panel, blink. Camera will not turn off, I have to take the battery out. Lens works...

Maybe there is something wrong with your batteries? Replace them. I had the same experience with my D200 and a Nikon 18-200 lens, later with my Nikon 10.5, Sigmaa 135-400. After replacing the battery everything worked as ever.

HELP! How do i replace the main selector button on the back of my Nikon d200? The large button that toggles picture review? My broke and I need to replace it. Thanks! Patti

Patti, replacing switches requires the outer case to be dismantled and a job for a service person. I don't know where you are in this world but the D200 is still a good camera and well worth the dollars to repair it. If it were one of mine I would send it back to Nikon or a Nikon authorized repair center.
Probably not the answer you wanted but working on these cameras isn't like changing a light bulb.

My Nikon d40 is all of a sudden taking dark pictures

Silvanus is correct - I have a D200 and often by accident adjust the exposure bias dial when taking the camera out of my backpack resulting in dark shots. I bet this is your problem.

Nikon D200 / photos coming out magenta somtimes blue

Set it to a manual white balance colour temperature, 5200K being an average one to start testing at. Does this make a difference? If not, then the sensor, RGB lightmetering sensor or exposure board may be at fault. The peripheral area of most sensors is used for white balance metering, which denotes a sensor issue, although if the exposure board isn't reading this information correctly, then it will give varying results. However, Nikon's 420 pixel RGB sensor on the D200 may also be taking WB readings. I'll be talking to Nikon soon, but try manual settings first.

Total shutter counter D200 (maintenance menu?)

Nikon doesn't make that information available; but if you want, you can try IExif. It is a freeware program which purports to be able to give you that type of information and more from your digital camera. It is available at the following link:
