<p>Thank you very much Marc or this detailed information and interesting picture. I now have a clue about the problem. I assume it could be caused by a lot of problem (broken or dirty sensor or emitter, broken mechanism, blocked holes on the wheel...).<br>

The seller agreed to take back the camera and reimburse me. I think that's the best solution, since the problem can't easily be solved.</p>

<p>My F4 sound seems normal when shooting either in A or S mode. The red LED blinks. On the youtube video it stays on.<br>

<br />I found some info <a href="/nikon-camera-forum/00NRqy">here</a> and <a href="/nikon-camera-forum/00SJKC">here</a> on photo.net, and it looks like the problem I encounter with my camera.</p>

<p> </p>

<p>I locked the diaphragm in its smallest aperture. As you said, FEE is displayed if you don't lock the aperture ring, and one can't take take a picture. I can take a picture in S mode but the red LED blinks and the camera freezes.<br>

This morning I managed to take a picture in S mode but that was at the lens' largest aperture (automatically set by the camera of course).</p>

<p>Hello,<br>

Some days ago I bought a Nikon F4S. I think there's a problem with exposures modes other than A or M. When using it in shutter priority mode, the alert red LED blinks after each shot. It's located near the film rewind knob. It's then impossible to take another picture. I have to shut down the camera. If I stay in shutter priority mode and take another picture, the red led blinks again. However, if I switch to the A mode, the camera works correctly. That red LED blinks when there's a problem with the film advance or when the camera cannot set the aperture of the lens. Since I can take pictures in A mode I think there's no problem with the film advance. Therefore I think the camera cannot set the lens aperture when taking a picture in S mode. I tried several lenses : 50mm AF-D f1,8, 24mm AF-D f2,8, 35mm AF-D f2. I get the problem with all of them.<br>

What's your opinion ? Do you had such a problem with a F4 ? How does the camera set the aperture of the lens? Is it with the lever located on the left side of the mounting flange ? It seems to be ok on my camera. The electrical contacts are clean.<br>

The seller told me he always used the A mode and wasn't aware of that problem. He's ready to take back the camera or reimburse a fraction of it price if I decide to keep it.<br>

For the moment, I shot 1 roll of film (staying in A mode), and another one is in the camera. I plan to make a lot of tests with the camera when I'll have finished that roll.<br>

Thanks for your opinion/advice !<br>

I'm French and I live in Paris. Using a tripod in Paris won't get you into trouble, unless you shoot right under the Eiffel Tower for example.

Some areas in Paris aren't really safe. All the areas around the Eiffel tower and the Louvre are safe.

Paris lights are sodium lights. Those lights are just horrible. A few places in Paris use tungstene lights. Those lights are now used only for historical monuments. All other streets use sodium lights.
