Hi Stuart,

>(aperture priority works that way anyhow), and just meter the

Remember that the Aperture diaphragm is always wide open except when the DOF Preview button is pressed or just before the shutter is released, the stop down mechanism on the camera stops down the aperture diaphragm to the f stop set in the camera. Since the D60 does not have the mechanical linkage to sense the aperture setting on non-CPU lenses there is no way for the D60 to set the correct aperture.

>Seems like just software....

It requires more than just software. Software will work if the lens is chipped. Mechanical linkage is required for the camera to sense the aperture setting.
Good Luck and Enjoy your Nikons!

Best Regards,
Marty
