It's serious enough that you will not be able to fix it yourself. You should send your lens to Nikon for a repair estimate. You will find information on the Nikon USA website regarding where your closest Nikon Repair Depot is located and return procedures.

SOURCE: repairing 20mm af nikon lens diaphragm lock

I'll offer the same answer I just gave on a D200 question: With the lens off, look at the camera mount area. If you are looking straight at the mount, there is a small tab sticking out at about 7oclock on the outside edge of the mount ring. The tab is spring loaded and may be damaged. You should be able to push the tab toward the base of the camera and it will snap back if functioning properly. If it feels loose or doesn't spring back, then switch that ab controls is not being activated.

I cannot take photos when i shot with manual mode.The shutter clicks but no picture is actually taken.Darkness.The auto mode works fine.Lens Nikkor Micro AF-S 105mm.Drives me crazy


When you shoot in manual mode, make sure your camera sensor gets enough light. When you shoot inside with dimm light at 1/1000 of a second or faster and a aperture of 8. all pictures will be black.
The best way to learn shooting in manual, is to shoot a picture in the P mode and put the picture on the screen (>) button. then select the info, where you see time, aperture iso and so on. and even better select the histogram. Note the figures in your head (or on paper) and then goto manual and make sure you have almost the same settings. Then shoot en look what the histogram shows. No histogram on the right, means to little light, so lower the shutter speed, open the diaphragm or increase the ISO. No histogram on the left, means to much light, so higher shutter speed, lower ISO or smaler diaphragm (the aperture number must be up. 3,6 is wide open 16 is almost closed.

Sometimes pictures are dark even in auto mode, err message is always coming, dark image in the view finder.


Hi dear pmorala
1) check
the lens if to drive the diaphragm actuating lever that opens.
2) also check the aperture lever on the camera body may be broken or bent.
3) look at the Shutter release the mirror and shoot the camera in a low speed (M mode) note if this works correctly or some of the leaves that make up the curtain is loose or out of place.


Everything seems fine ... OK command dial to select the full aperture, shoots the camera at you and see the diaphragm (set M mode and speed sh bellow 1 / 8). Full closed? = Aperture Mechanism defective.

Sounds to me like the aperture diaphragm on the lens is stuck in a small opening position. If you detach the lens from the camera and look through it, is the whole opening light or just a small dot in the middle? The diaphragm can stick if it gets a drop of oil on it.

I have turned camera on and set up to take a photo and the shutter release button will not press in to take the photo. I used the camera yesterday and it worked fine!


Turn the camera on and look into the view finder while you try to press the shutter button. Check the information in the view finder to see whether you are getting an error message. If you see an error message in the view finder, remove the lens cap and proceed to take a photograph but, instead of pressing the shutter button this time, press the button near the top of the camera on the back which says "AF/AE. If the camera takes the photo it means you have somehow initiated the auto focus/auto exposure lock which the camera will not override when attempting to take a photo using the shutter button. When you use the AF/AE button, you override this system. To remedy this issue, when you get the error message try pressing the shutter button again. Also, remove the lens to see if the shutter inside has frozen in the "locked" position. If you find this to be the case you will need to contact Nikon Customer Support. The link for Nikon Support is below. The numbers are half-way down the page.

ERROR 99


Error 99 is a generic error in that the camera does not know what the exact error is. The usual fix for this error is ......

Turn the camera off and remove the battery.

Remove the lens and clean the electrical contacts on the rear of the lens with a soft dry cloth.

Refit the lens and the battery and switch back on. Hopefully all will be well again.

SLR not working


The lens you are talking about has either:
1)a faulty diaphragm mechanism ( lens stays closed at f 22 or f 16 when you attach it to the camera instead of opening fully as it should ) . or
2) the lens is fine but the diaphragm coupling mechanism inside mirror box ( on the left hand side if viewed from the front ) is not engaging the lens properly so that your lens stays fully closed ( F 22 /16 ) : because diaphragm stays fully closed image in viewfinder appears v. dark.
Solution ? have a camera technician take a look but my guess is that the diaphragm needs cleaning and it should not cost you more than $ 80 bucks.

Dark view in view finder


Sounds like a lens diaphragm problem ( lens stays closed down to F16 and that is why you have a dark viewfinder ). Remove lens and see if you can activate the aperture mechanism via the activator which protrudes from the rear of the lens. You should get nice and brisk action from the aperture . If the movement is sluggish or the lens stays fully closed then your lens needs attention.
