Hi

A Zorki I does not have the built quality of a Leica II but should still work ok.
The earlier ones are slightly better but have more quirks.
You pays your money you makes your choice.
The collapsible lens will accept the Leica FISON hood or you can make a paper machie one. With a hood the little lens should be real good.
The provisio is that it needs to be free of kitchen table maintenance, before you buy it.
