I have a Nikon D60 and have just bought a 50mm AF 1.8 D lens but find I can only use the aperture setting at 22. Is that right ?? why can't I use the other aperture settings ??

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.
