[QUOTE="aroy, post: 498700, member: 16090"] You have to use the aperture ring on the lens to set the aperture. Note that the lens will be wide open, till you shoot. When you press the shutter, the body will move the aperture lever on the lens, so that it closes the aperture. The mechanical linkage will close the aperture, and there is a hard stop at the set aperture. If the lens had a CPU, then the camera body would know how much to move the lever to get the required aperture, as there is no CPU, the lever is moved till the aperture closes to the set value.
