I was looking at the Nikon Normal AF Nikkor 50mm f/1.8D Autofocus Lens and found out that when I attach it to a Nikon D90, the only way it works is by turning the aperture ring (on the lens) to F22 - all other positions show an FEE error on the camera and can not take shots.
Is it because it's a D series lens and the camera can adjust the aperture from the body up to F22 (so any other settings on the lens conflicts this)?Ii realise that for G series lens there is no aperture ring on the lens which is kind of useless if the camera can change aperture from the body itself.
Another question that comes to mind is about Macro (micro) lenses. What is the main difference between (say) the Micro-Nikkor 60mm f/2.8G and the normal 50mm f/1.4G lens? The normal lens has a lower aperture (1.4) as opposed to the micro (2.8) so the depth of field can be used better in the normal lens. Is the only advantage of the micro lens is in it's 1:1 magnification and very low minimum focal distance (7.3" as opposed to 1.5'). Of-course there is price difference (50mm f1/8D - USD119, 50mm f1/4G - $429 and 60mm macro - USD539).
Thanks a lot for your assistance.
