Todays' Nikons DSLRs require lenses that have aperture rings to be set to their minimum apertures. So you're good to go. You aren't always shooting at f/32.... you can change the aperture with the camera. But the lens needs to be set to minimum so it can utilize those small apertures if you set the camera for them.
The chip in the lens (via the electrical contacts) tells the camera the minimum aperture is f/32. If you look closely at the aperture ring on the lens, you'll notice the part that mates with the camera is not smooth.... there's a notch in it. That notch marries up with a ring around the camera's lens mount. That keys the camera to what the minimum aperture is of the lens you've mounted. This is how your camera 'knows' the lens is not set to the f/32 minimum. If the two do not match up, the camera will display the FEE error and refuse to fire.
