This lens has the same optics as MD zoom 35-105/3.5-4.5,
135s in the right lower two tables are misprinted, S/B 105.
At 50mm the lens is pretty good, some says better than 50/3.5 macro.
MTF graphs are actually measured ones by testers, not by Minolta.

I guessed this lens was TOKINA made one?, whose MF version has identical
optical design, although Tokina said 35-105mm F3.5~4.3(←not 4.5! :)).
