No they're not. Push the GB and the lens and camera communicate, the aperture is recorded and exposure info is calculated, shutter speed is adjusted. The camera and lens just communicate differently. Plus, by activating the DOF button, the camera provides a read out in the viewfinder of how much over/under the exposure is. That's more than some film bodies delivered.
