One
of the well-known problems with those FSU rangefinders is the particular
design of the viewfinder, which seems to be developed to scratch your
glasses in the first place! Why the Soviet engineers did it in this way
is completely beyond my imagination… Thinking of a solution for my
Kiev-4A, my eyes fell on the lid of one of those Fuji Velvia slide
boxes, the no-flat black ones. After cutting the ridge on the outer edge
and the central part, it just fits tightly around the Kievs viewfinder!

Now, THAT’s a Soviet solution!!! Although… probably too sexy looking …

A cheap solution...
