Pb with pentax smc lens fa 1:4-5.6 35-80mm

I bought on ebay a pentax smc lens fa 1:4-5.6 35-80mm and I am not satisfied with the automatic adjustment (slight blur).

it moves laterally at the focus rings (this may be normal) and the drive axis at the back of the lens rotates 45 from one tooth to the other with respect to the front lens drive wheel? (it's difficult to explain).

I recently took pictures with a photo test pattern to highlight front or back focus, but I don't think I'll be able to correct it on the ZX-L body, or on the lens.

in the attached photograph, the automated system seems to have favoured the bush on the left and not the infinite.
