[QUOTE="Bob Blaylock, post: 299468, member: 16749"] With CPU lenses, the camera wants to control the lens' aperture setting. It does so via a lever on the back of the lens. In order for the camera to have this control, the aperture ring, if present, needs to be set to the smallest aperture. As it happens, I had occasion just a short time ago, in connection with another thread, to take and post a picture showing this lever, albeit on an ancient non-CPU, non-AI lens. [ATTACH=CONFIG]85985._xfImport[/ATTACH] I suppose that would depend on the lens. The stock 18-55mm lens that comes with the D3200 has an aperture that varies by a bit more than one ƒ-stop as the lens is zoomed from one end of its range to the other. It does, of course, know how to communicate its correct aperture setting with the camera, accounting for this change. I'm assuming that the lens to which you are referring does not communicate this variation to the camera, and possibly has a much bigger variation to begin with. You may just have to figure out how to compensate manually for this variation. [/QUOTE]
