Here are the long lens test results. First, the overall scene, reduced in resolution to 600 pixels wide:
The Tair-11 133mm:
The Pentax Takumar 135mm:
The Tamron 70-210mm at 135mm:
Now here are two 600x400 pixel details from the full 2700 dpi scans:
The Tair-11 133mm text detail:
The Pentax Takumar 135mm text detail:
The Tamron 70-210mm at 135mm text detail:
The Tair-11 133mm stone detail:
The Pentax Takumar 135mm stone detail:
The Tamron 70-210mm at 135mm stone detail:
Overall, the Pentax Takumar 135mm is the clear winner. The Tair-11 is nearly as sharp, but much less contrasty. The Tamron's performance compared to these two is disappointing -- enough so that I'm suspicious the focus may have been a bit off.
