It's not that scientific a study. The birds don't sit still while changing lenses so the distances are not exact, although I did try to get approximately the same. Looking at all the images I took it is difficult to see much difference on most of them, but there are one or two with the Tamron which do look sharper.
I'll maybe try a more scientific apporach tomorrow if the sun shines.
