The Japanese camera industry is very confusion as it's difficult to find out who made what, subcontracting, who made the glass, who constructed the optics and so on..........So Hanimex was a front name for lenses and it's all hit and miss for a VG\poor lenses. The only Hanimex lens I've picked up was a 28mm and it's absolute crap (which equaled my Osawa 28mm, maybe Osawa made the Haninex 28mm)....... but your 135mm might be a good one.
If you want a 135mm lens best to stick to ones recommended but even then you could get a friday afternoon lens because of copy variation.
