Chinamen are shilling their subpar lenses and you fall for it. Soviet lenses have decades of reputation by being common kit lenses for Zenits.
You can't start building quality optics in a hurry, Soviets had decades to create their Zeiss clones and mass produce them. Creating optics is very expensive and thus Soviets churned the same lenses out for decades, the more they made them the cheaper they were in the end.
Chinese stole blueprints from where ever and kickstarted their own factory line releasing a new flavor of the week lens constantly. Their build quality is shit, a Soviet lens will be here and usable when you are already gone, a Chinese one will not even last daily use. Quick googling reveals those Chinese lenses falling apart.
>>3359269Everyone loves Soviet lenses.
Stop shitting the environment by buying single use crap.
