The D type and G type lenses provide 3D Matrix metering and 3D Multi Sensor Balanced Fill flash. The pre-D type lenses use Color Matrix metering. As stated above, the distance informations increases the exposure accuracy when using flash. I have both the AF 35-70mm f/2.8 and the AF 35-70mm f/2.8D and in practice, 99.9% of the time the difference in exposure negligible between the two. Good Luck and Enjoy your Nikons!
