Zorki 4 Vertical Rangefinder adjustment - A discovery

[comp_wiz101]

I have discovered something about the Zorki 4 Vertical rangefinder adjustment. Instead of adjusting the mirror inside the rangefinder via two screws (as suggested in a previous post), it can simply be adjusted in almost the same way as my older Zorki C. The rangefinder prism can be rotated much in the same way as the older Feds and Zorkis. Using a small set of pliers, the prism can be rotated until vertical alignment is correct.
