You should be aware that a few lens will shift focus with aperture change.  So the camera acquires focus at full aperture and then stops the lens down for the correct exposure which can result in a focus shift. The Minolta 50mm f/1.4 is known to exhibit this characteristic. This is mostly seen in large aperture lens.
