Tan, Manual aperture setting on the lens is considered more accurate, there've been reports that from-the-body aperture control can err by as much as 1/3 or 1/2 stop and is inconsistant in its degree and direction of error. In addition, lenses from before the A-series can't support from-the body aperture control.
