Such tests are really hard to do. The Tessar looks a bit mis-focused at
f/8 (see the blue band on the vase) and the Tamron is obviously at a
different focal length as seen in the perspective. In a digital world
there's probably not a whole lot of performance difference to worry
about here... at least at this image size. That said, the Tamron did
very well for such a long range zoom.
