[QUOTE="Bob Blaylock, post: 545484, member: 16749"] Your post had me thinking. G lenses depend on the camera to control the aperture via a mechanical linkage that was originally intended, in older cameras and lenses, just to be used to provide the feature by which the aperture is wide open during viewing,and then closes down to the setting selected on the ring when the picture is actually being taken. It was the AI-S step in the development of this system, in which this linkage was calibrated to allow it to be used to control the aperture in an accurate manner. The F2 was the last fully-manual camera in this line, and it seems to me that any camera that supports shutter-priority automatic exposure ought to be able to control the aperture via this linkage. The Wikipedia seems to back up what I am thinking, that even if you cannot select any but the smallest aperture setting in manual, that you can operate it in shutter-priority mode and get larger aperture settings: [indent][i]Its lack of electronic aperture control limits the F4's functionality with G type lenses, which do not have an aperture ring. With these lenses, exposure control is limited to program and shutter-priority modes. In addition, DX lenses are not designed to cover the full 35mm frame and will vignette when used with the F4 (or any other 35mm camera).[/i][/indent] Anyway, you can certainly use those lenses, in any event, if you're willing to be limited to the smallest aperture.
