I just got this lens and I really love it, but I can't seem to figure out why it will only take pictures at f/1.8. If I attempt to change the lens aperture setting, it says the aperture must be set at its lowest setting. The lens is AF but I can only manual focus on the D3200. Is there a setting I need to change, or a special way to set up the camera to be able to change the aperture setting on the lens, or is that just how it is for this camera?
@Scott Reed I have the same lens in Nikon F100. In my camera I have always set aperture to f22 in order to be able to set the aperture from the camera. Try to lock the lens in f22. Which exactly 50mm lens, do you have? Nikkor 50mm 1.8G or nikkor 50mm 1.8D? I am guessing that you have 1.8D which came without auto-focus motor. Moreover, neither the lens nor your camera have got auto-focus motor, thus it's normal that you can't auto-focus.
