Nikon D610 No longer recognizes SIGMA Lenses

<p>I am baffled with a couple of issuss n my D610. I have been using SIGMA 24-70 2.8D and SIGMA 15-30mm with this body for sometime. Yesterday, when I mounted the 28-70mm lens, I saw an fEE error on the top LCD display. I checked the tab that locks the lens aperture at its smallest, and the tab was in place. The aperture ring did not move. When I turned the camera on, it displays fEE error and refuses to function. I tried anther lens, SIGMA 15-30mm, same result. I tried the SIGMA 50mm 2.8 macro lens, ditto.</p>

<p>I then tried a NikonAF 50mm 1.8, same result. When I mount the 28-300mm AF-S VRII, it works fine. This lens comes with the body and I use it was my walkraound.<br>

Then I mounted a Nikon 105mm 2.5 AI, set Non CPU lens accordingly and select it. which used to work before, as far as metering is concerned. Now I can longer meter with this lens, the aperture is not correctly reflected in the display in the viewfinder. It stays at 11 no matter where I turns the aperture ring on this lens.</p>

<p>In sum, I am experiencing two distinct problems:<br>

1. Not recognizing NON-Nikon lenses, even though these same lenses work on this body before.<br>

2. No metering with Nikon AI lens.</p>

<p>I checked/cleaned all the contacts on the lens, and cleaned the contacts on the body. These lenses work fine on a D7000 body.<br>

Are there any settings in the D610 that have anything to do with these issues? I tried all the things I could think about to correct the problem, all to no avail.</p>

<p>Please help if you have any experiences on these issues or ideas on how to overcome them. Thank you all.</p>

 

<p>It definitely a service issue.. I have the Nikon D40, Nikon D3s The Nikon D4 and the Nikon Df, and all my lenses AI, AI-S, to AF, AF-S, zooms and prime working all the time properly. I haw no D610 or D810. Your camera has to be checked.<br /> Bela</p>

<p>Thanks for you reply. I figured out that the camera now only works with G lenses. Something is amiss with the aperture follower tab and its associated components. <br>

I will call Nikon Tech Support for a repair tomorrow.</p>
