Some lenses are obviously rebadges. The Sony 135mm STF is identical to the Minolta one, except the color of the focus and aperture rings and the company name printed on the barrel.
Most of the SAL lenses also have a corresponding Minolta variant. If you can find a Minolta lens that has the same aperture range and focal length as a Sony lens, chances are they are identical. Some "Sony Zeiss" lenses may also simply be Minolta designs with coating tweaks, but this is just a theory I have with the Zeiss 85mm F1.4 being optically almost identical to the Minolta 85mm...
