This isn't a fair comparison, as the technology is pretty far along since the Tamron. The Adaptall-2 system isn't going to give you the precision of an integrated unit in the first place. Finally, the Tamron coatings in those days were a bit weak compared to better OEM competition. Then there is the whole matter of losing the better part of two stops which will reduce the precision of your focus peaking.

Samyang low light shots - first is K-01, second is K20D

Lucinda Williams - 85 f/2

Joe Cocker (a dog) 85 f/2.2
