Looks pretty decent to me, however how do you rate its flare ?
flare has been a major issue with Tokinas in the past
By the way, the Tokina AF 100mm f/2.8 AT-X Pro D macro uses a Pentax-patented optical formula, that of the F / FA / D FA 100mm f/2.8 Macro which wad licensed to Tokina (among several others) when the then independent and listed Pentax company struggled to survive.
The first incarnation, the smc Pentax-F 1:2.8 100mm Macro, dates back to 1987. The latest and still current one is the smc Pentax-D FA 1:2.8 100mm Macro WR.
I'm using tokina 100 macro for more than 10 years. Moslty on my canon 50D
Lens is as sharp - Bokeh CA - fins a workarround - shooting BW or loca reduce of saturation in Photoshop
Flare resistance is good for Tokina lens but far behind my Sigma 150 non OS macro
My copy shows front focus by distance more than 7...10meters.
Easy to solve with AFMA
Another issue is the aperture PCB, but if you are handy - the PCB costs 5 Euro
Do I gonna buy this lens again - no is sigma 105 OS IF is just 50..70euro more

"gold old screw-drive for autofocus instead."

It's certainly not "gold", and it being "good" is also debatable.
I hated such lenses with a passion when I had the misfortune of using them. Thankfully it was all the way back in the (personal) Mesozoic era.
Luv it! :lol: Keep 'em coming.
Oops, sorry, somehow missed your hint. good/gold now replaced by old-fashioned
