Re: Aperture priority not working...HELP!!

Hey Mike, This is an easy one. With the battery grip attached, you can only have either Shutter Priority or Aperture Priority work properly. You can change it with the custom function settings of the camera. So you can change it to work with Aperture Priority if you use that more so then shutter priority won't work. Brandon

Nikon N65 with Nikkor 35~80mm AF lens will not focus or shoot

N65s were notorious for bad shutter release buttons. The metal is thinner than a strand of hair and they break. Search Ebay and see if the part is available to replace (note: Nikon stopped selling parts last year).

What does FEE mean? The camera won't take a picture and I see that in the display of my Nikon N90S

FEE error message displayed on SLR camera LCD Description If the cameras LCD screen displays "FEE" in the area where the aperture is normally displayed, please ensure that the lens is attached to the camera correctly. This error message will appear if the lens is not attached correctly to the camera or if you are not using a CPU lens such as the Nikon AF or Nikkor P lenses. Alternatively, if the lens has an aperture ring, it may not be set to f22 (or the highest aperture number on the aperture ring - normally marked in orange). Select the aperture number marked in orange on the lens and lock it using the aperture locking switch to prevent this occurring again.


The FEE error message

Set to F22, or the highest aperture number - normally marked in orange. Note the locking switch.
If the above did not resolve the problem and you still experence the the error display FEE, please contact your local Nikon office. Before doing so please also check the following.


1157d.gif That the EE servo coupling highlighted above on the lenses has not been broken. That the F-min switch highlighted above on the camera body has not been broken. If either of the two items above are broken please contact your local Nikon service center.

I'm doing a project for school and i need to change the aperture for different photos. But my camera refuses to take the photo on any other aperture. Why is there an aperture adjuster if you can't use it....

It depends on the lens.

If you're using a lens with an aperture ring, simply set the exposure mode to Manual or Aperture priority and change the aperture by turning the aperture ring on the lens. In Aperture priority the camera will set the shutter speed appropriately, in Manual you have to determine the appropriate shutter speed. If you want to use such a lens in Shutter priority or one of the Program modes, you must set the aperture to its smallest setting (largest f/number) and lock it.

If you're using a lens without an aperture ring then it's a bit harder. You can only use the camera in Shutter priority or one of the Program modes. You turn the command dial on the camera to change the exposure, and the aperture will change. If you want to use an exposure different than what the meter suggests, you can adjust it by using either exposure compensation or changing the ISO setting (or both).

Hi, I have an old Nikon F90X with Nikon AF NIKKOR 28-200 mm lens. Can I use this len in othernew Nikon digital camera? Thanks, Tz

Yes. But unless you're using one the the expensive full-frame models the lens will produce images that are magnified by a factor of 1.5. So your 28-200mm lens will behave like a 42-300. Aperture values are unaffected though. On the plus side, the fact that DX sensors only use the middle of the lens image means that the pronounced image pin-cushioning is greatly reduced, and the vignetting (darkened corners) is also reduced.

Both versions of the 28-200 (AF-D and AF-G, click for details courtesy of Ken Rockwell) lack an in-built focus motor, so autofocus only works with Nikon bodies which have an AF motor built in. Not all the digital models have them, but if that's the case with yours then you can still focus manually.

Please take a moment to rate my answer.

MY CAMERAS SAYING FEE, its not working

This is found in the F80 manual page 99. it means the CPU Nikkor lens (other than G-Type) is not set to its minimum aperture. Solution: set the lens to the largest f/stop such as f/22. This FEE error is the same for almost all Nikon cameras, be they film or digital.

Nikon f100 will not powerup when turned to on...

Sounds as though the fist thing I would do is check the batteries. Also, if the batteries are good then check the battery holder for corrosion. Are you using the small battery holder or the MB15. Sometimes folks do not have the MB-15 screwed in tight.

Nikon F100 suddenly went dead

Which battery holder are you using? The small one or the grip MB-15? If it is the MB-15 make sure it is screwed in tight. If it is the small one then make sure your batteries are in the correct direction. If that does not work call Nikon Film 1-800-645-6687.

Error message shows F -- with lens attached. Lens was cleaned with compressed air, now willnot work. Lens type Nikon 28-80 AF

Check to see that the lens aperture ring is set to the smallest (largest numerical) aperture setting (usually f22 or such). Nikon AF cameras have to have their lenses set at the smallest aperture for most of their program modes to work. Nikon AF lenses have a small slide or twist lock adjacent to the aperture ring to lock it in place at the smallest aperture. This may have been unlocked during the cleaning.
Another possibility is that the lens's electrical contacts were damaged during cleaning, so the body is not "seeing" the lens. Do you have another lens you could attach to the body to test this theory?
