problem with d7000

[lifeflower]

I have a D7000 and have it set on the shutter priority setting.. on the display settings panel where the appeture should be shown there is a flashing f-- being shown and the shutter won't work...any suggestions..I can't find anything in the book?()
Thank!

Check that the lens is connected correctly. By the way, which lens are you using?

[Mike Buckley]

Check page 302 of the D7000 User's Manual for possible causes. John asked about which lens is being used and my guess is that he is getting to the point that a non-CPU lens might be attached. If so, it will work in Aperture Priority or Manual mode but not Shutter Priority or Program mode.

EDIT: The page number I mentioned pertains to the English version. Your version may be a different page number. Even so, it's one of the first pages in the Troubleshooting section.

I have a feeling that is because the lens can't reach the aperture needed by the speed setting. If so set a faster shutter speed until it stops flashing.

This might also happen the other way round - can't reach a high enough slower F stop for the shutter speed that has been set buy I would guess that will only generally happen when a rather high iso has been set.

The camera will do this if you are using an AF lens that is not a "G" version (like a "D") and don't have the aperture ring set at f/32 or what ever is the minimum for the lens. There is a lock switch that should be used to prevent you from moving the aperture ring by mistake.

Yes, that is what I was suggesting regarding the lens. I checked the Nikon website and it stated that a FEE symbol will appear if the camera cannot control the aperture range of the lens, the F-usually indicates no communication between camera and lens, dirty pins is also listed as another cause.

Ooops, you are correct and I didn't read the OP's post carefully enough.

I am new here and got confused by this... Does camera restrict from going beyond specific aperture range, even if lens is capable of reaching that wide or narrow? Why would that restriction be? I always thought camera gets the possible aperture range from lens and itself does not decide the limit.

Part of the confusing terminology used by camera/lens manufacturers. The maximum aperture value (widest aperture) is limited by the lens capability, lens designated as f/3.5 can't be opened to f/1.8. The minimum aperture value (narrowest) is also limited by lens capability, lens can't go to f/32 when set at shortest focal length but can at longest focal length. If you have the 18-55mm kit lens, set the camera to aperture priority and 18mm and see how narrow you can set the aperture, then try at 55mm.

A slight correction to John's comment - the aperture range has nothing to do with it, but rather the camera's inability to automatically set the required aperture of the lens at all.

All this means that a modern / lens combination need to be tied together electronically for some of the automation to work. An older lens (without the CPU contacts) or a more modern lens that does not have them means that the camera / lens combination cannot communicate and automatic functionality will NOT work.

Even some modern lenses (i.e. those that are currently being produced) may have this issue. My Nikkor f/3.5 24mm PC-E (perspective correction) lens displays the "fEE" message in anything other than manual or aperture priority mode, simply because of the way it was designed. Unlike the other modern Nikkors, I have to set the aperture via an aperture ring on the lens and cannot use the on-camera command dials. The also has no autofocus capabilities; it has to be manually focused.

So, to simplify, automation depends on the camera and lens having been designed in a way that allows them to communicate. The error message simply tells the photographer that the camera / lens combination cannot do what is being asked of it, either by design (as in my example of the 24mm PC-E lens), backwards compatibility issues (using an older lens or modern lens without the CPU contacts) or a damaged lens or camera body (CPU contacts).

To me it's a hardware fault. If the software of the camera wants to exceed the maximum or minimum of the lens, I get a lo or hi sign.
