These identical examples may help if these are uploaded in a useful size. The first image is my Minolta 75-300 at 300mm. The second image is my Tamron 5 pin also at 300mm, the subject is about 5 metres away and a speedflash was used on a Sony A290. The Minolta has much better clarity which can be seen mainly in the stitching on the black jacket near the velcro patch which was the point of focus. The Tamron has never given me the clarity I've wanted, always just a little out of focus and the colours are always washed out and dull. I'm assuming with my limited knowledge of the electronics that it's to do with the pins. I definitely won't risk a 5 pin lens again.
8 pin
5 pin
if you disabled those contacts on both lenses (and used them fully on manual ) you would still have the same difference.
BTW, I had to micro focus adjust one of my Sony lenses (probably made by Tamron) but did not have to adjust my two Tamron lenses.
