No. In Av mode the camera seems to shoot with the lens wide open, no matter what you set the aperture ring to. It *does* stop the lens down briefly, but only after the exposure has been made. Very strange. (I suppose it's idiot-proofing; the metering is locked to full aperture, so an auto-exposure is made at the same aperture. I don't know why the aperture stopdown has to be trigerred at all, though.)
