In 1971, “Kiev6” is produced by Arsenal (USSR/Ukraina).It has a same lens mount with “Pentaconsix”. Many texts wrote that “Kiev6 is copy of Pentaconsix”.
I think, it is half of right, half of wrong.
Oriented characteristic is same. So, easy use medium format SLR.but Detail differs. Another camera which has the same clasp or The on the basis of Pentaconsix and produced in Soviet interpretation.
When it compares with Praktisix, Kiev6 has range of vision is widely. It is larger than Exakta 66.
