kevin_mulholland1 Posted April 17, 2006 Share Posted April 17, 2006 I hope this is not a repaet - I seem to have been unsuccessful in a previous post............ I have a Nikon D50 that works fine with an AFS 18-70mm lens and older AIS lenses (on manual). My older AF lenses (60mm micro and 70-210mm) no longer seem to communicate with the camera - I get a FEE message and nothing works. They did work last week. Any ideas? I did reset the camera to its default settings but it did not solve the problem. Thanks. Link to comment Share on other sites More sharing options...
klix Posted April 17, 2006 Share Posted April 17, 2006 It IS a repeat. Check the archives. FEE means your lens' aperture is not at its minimum setting (e.g., f22). Your 60mm and 70-210mm should have a switch that locks the the aperture setting to the minimum. And BTW, AIS lenses will mount on your D50 but won't meter.

kevin_mulholland1 Posted April 17, 2006 Author Share Posted April 17, 2006 The lenses are locked on their minimum aperture - sorry I should have said that. Link to comment Share on other sites More sharing options...
ky2 Posted April 17, 2006 Share Posted April 17, 2006 Actually, AIS lenses have no aperture "Lock Switch". Just use your camera at Manual mode, and set the aperture as you would always have set it-- with the aperture ring. Link to comment Share on other sites More sharing options...

Whether AIS lenses have a lock or not is irrelevant with the D50 since it will NOT meter anyway. Kevin - Not sure what to tell you, if they're already set to the minimum aperture.

constance_cook Posted April 17, 2006 Share Posted April 17, 2006 Kevin: Not to insult you, but you have the lens set to minimum aperture but did you push the little lock tab over? Conni Link to comment Share on other sites More sharing options...
ShunCheung Posted April 17, 2006 Share Posted April 17, 2006 As long as the aperture ring is set to its minimum aperture, you should not get the FEE error. That little lock tab does not need to be in the locked position, which is for preventing the aperture ring from slipping out of its minimum setting. The next thing I would try is to clean the electronic contacts around the lens mount, on both the body and the lenses. Make sure that you have a good metal-to-metal electronic contact.

joseph_wisniewski Posted April 17, 2006 Share Posted April 17, 2006 Shun is right, sometimes it is the contacts. I hope he's right this time, because a simple contact cleaning will fix the camera. If it's what I think it is, your camera needs to go into Nikon service. AF and AF-G lenses "tell" the camera that the lens is at minimum aperture (it doesn't have to be locked) by pressing down a little switch on the camera. It is possible for this switch to be damaged. Sometimes the damage happens when you mount a lens wrong, other times it happens when you mount an pre-AI lens (even one that's been "converted to AI, if the conversion isn't done well). Damage from pre-AI lenses is cumulative: the first 47 times you do it, you may not see a problem, but then one day, one mount too many... "G" lenses (your 18-70mm is a "G") don't use the tab, they communicate to the camera that they're permanently locked on minimum aperture. So even if the switch on the camera is damaged, they still work. It's also possible for the little projecting tab on the lens that actuates the switch to break off, but that would leave one of your two AF lenses working. It's highly unlikely that they formed a suicide pact and both broke their tabs in the same week. Link to comment Share on other sites More sharing options...
klix Posted April 18, 2006 Share Posted April 18, 2006 It could very well be the electronic contacts, but the typical error message with bad contacts is "F--" so who knows? Link to comment Share on other sites More sharing options...
kevin_mulholland1 Posted April 18, 2006 Author Share Posted April 18, 2006 Sadly, I think Joseph has it right! The contacts are clean but I do use an old AI'ed 300mm lenms and I think that was the last lens I mounted (other than the G lens) before I noticed the problem. I'll have to call Nikon.

ron_yeager Posted June 9, 2006 Share Posted June 9, 2006 Really new at this thing, but I have the D50 as well, and getting the same message. My question, why will the camera not operate unless the lens is at the minimum aperture? Thanks for any response. Link to comment Share on other sites More sharing options...
ShunCheung Posted June 10, 2006 Share Posted June 10, 2006 If the lens has an aperture ring, i.e., it is not a G lens, it must be set to the minimum so that you can control the aperture, in its entire range, from the body. For example, if you have a 50mm/f1.4 AF-D lens and its aperture range is from f1.4 to f16, if you lock it to f16, you can then control the aperture from the body to anywhere between f1.4 and f16, inclusive. If you set the aperture to f5.6, there will be no way it can close down to below f5.6, and the range you could control from the body would have been limited to from f1.4 to f5.6. That is why the body displays FEE to inform you that you are doing something wrong. Link to comment Share on other sites More sharing options...

stuart_mckinnon Posted July 24, 2006 Share Posted July 24, 2006 Sorry to hijack an old thread but my problem is very similar. I have a Nikon D50 and have recently aquired a Sigma 75-200 F3.8 lense with a manual aperture ring. Rotating the aperture ring to f22 gets rid of he FEE message but I can't control the aperture through the camera. Whatever setting I use the display flicks between f1 and f4! Any idaes of what could be going wrong? Help would be much appreciated. Stuart Link to comment Share on other sites More sharing options...
ron_yeager Posted July 24, 2006 Share Posted July 24, 2006 Have you tried to adjust the aperture in manual mode? That is the only setting I know of where you can adjust the aperture. The aperture adjustment is done by holding down the button on the right just behind the power on/off ring. Hold that down and scroll left or right with the scroll wheel. Does that help?

stuart_mckinnon Posted July 25, 2006 Share Posted July 25, 2006 No that doesn't work either. The aperture number just flicks around all over the place. It mostly says '1' but then flashes '4' then '20' then...... and so on just picking random numbers. Any other ideas? Link to comment Share on other sites More sharing options...
