I have a question about magnification ratios in general. I thought that the focal length was the main determinant of how magnified an image will appear. I recently tested my 105 Nikkor AS MF lens against the auto Nikon 105 macro vr. The automated Nikon 105 had a much higher mag ratio than the manual focus lens, regardless of how I rotated the focus shaft.

I assume this has something yo do with the individual lens elements within the two different lenses. Can anyone explain this in simple terms?

Other factors are closest working distance and any extension behind the rear element.
