I think something wrong against soviet cameras. Big portion of APUG prefers Leicas , Hasselblads , Linhof , Rollei but when it comes to FSU cameras they wait miracles from 50 dollar Zorki. If you can try a Anamorphic Square Front 21 mm LOMO lens for 25000 dollars and see how soviet products work !
Trying to make a goal from cheapest product and compare with most expensive , is not IQ driven.
If you compare with japanese goods , there is no equivalent of sony , panasonic in usa also.
