I locked my nikon 50mm lens aperature ring to the appropriate setting for my Nikon D60, yet the camera still tells me to lock it into place, as if it is not registering the fact that I've locked it down already.

Yes. Just lock the lens aperture ring at its smallest setting (largest f/number). If you need to change the aperture, change it from the camera body by turning the command dial, the same way as with a lens without an aperture ring.

Then do so. Turn the aperture ring to its smallest setting (largest f/number). You can control the aperture from the camera body, the same was as with a lens without an aperture ring.

Set the aperture to its smallest opening (largest f/number) and lock it. You can control the aperture from the camera, the same way you do it on a lens without an aperture ring.

the lens needs to be set at its smallest f-stop to work properly on your camera. The F error is telling you that the aperure ring is not at the smallest setting(largest "F" number, most likely F22. turn the ring to F22 or whatever is the biggest number and it will work. there might also be a lock on the aperture ring to keep it from moving. Good luck, Worm1855

The D60 camera sets and triggers the aperture that you have selected (or the camera has selected if in auto mode) and sets the aperture as you take the picture. Moving the aperture ring on the lens will not work, in fact once you move it from the f22 position the camera will stop or possible show and error. on my older Nikon AF lenses there is a small lock to lock the aperture ring in the lowest position when mounted on a digital camera, it is found near the f2.8 side of the aperture ring. when you want to set the apertures manually, you put the camera in aperture or manual mode and set the aperture you want by moving the the rotating wheel on the grip part of the camera. the aperture you select will show in the window, you do not have to move the ring on the lens,it must remain the f22(highest numerical) position.

Make sure you set the aperture ring on the lens to its smallest setting (largest f/number) and lock it. Without doing so, the lens will not communicate properly with the camera and thus you will not get the autofocusing.

Hello,
The 50mm lens is fairly old and uses a different system to the later lenses. On the D90 and other later cameras you should rotate the ring to 22 and lock it there using the lock just above the aperture ring.
To adjust the aperture you use the front dial by the on/of switch.

Try it out in A mode. Rotate the mode dial on the top left of the camera to A (Aperture Priority mode) then lightly press the shutter button to turn the meter on. Then rotate the front dial and you will see the aperture reading changing.

The older Nikons changed their apertures using the ring but the later Nikons use the camera controls.

Hi I had a similar problem with a 50mm prime and I fixed it by locking the aperture ring on the lens in place.

The FEE message indicates that the lens is not set to smallest aperture (highest number). The camera body expects this so it will have full control of the aperture. It sounds like you may be accidentally bumping or turning the aperture ring on the lens while using it or changing lenses. There is a little slide lock to lock it at f/22 to prevent this. Turn the aperture ring to 22 and move the slider so the white dot is next to the orange mark on the lens barrel.

Hi, Is the aperture in max or min ?
Remove the lens. Try pushing the stop down lever and look through the lens if the aperture changes.
Look at this pic if you wonder what stop down lever means. http://www.mir.com.my/rb/photography/hardwares/nikonfmount/20AI-S2_8rearconv.JPG
