I'm trying to adjust the vertical allignment of my Zorki 4's rangefinder. The vertical allignment is off pretty badly--at 1 meter, the images look like they're about an inch or so apart.
A post on the Rangefinder Forum said that you have to turn the two little recessed set screws on top of the rangefinder mirror.
They turn freely but seem to have no effect on the split image.
I am able to get the images to nearly line up by loosening the two screws that hold the metal top plate (the one that holds the ball bearing in position) and shifting the plate forward and backward. But there has to be a way to fine-tune it.
What am I doing wrong? Is something stuck? |

Not familiar with the Zorki 4,so might be talking rot. The vertical alignment can be done by a rotating wedge prism on the right hand range finder window.(rt hand when looking through viewfinder)All my Zorki 1's and FED 1's have this system and the FED 5 certainly has.There were definite cost cuttings done on one of the Zorki 4 types ie painted numbers instead of engraving. So perhaps there are two types of rangefinder vertical adjustment.
Does the right hand window have a circular brass frame with 2 slots in it? If so use tweezers to gently rotate clock or anticlockwise until images coincide.
If all the Zorki 4's use the cheap and nasty 'move the mirror' method, then I would suggest that the mirror is somehow stuck. |

Yes, Glenn has it. The difference with the Zorki 4 is that the top cover has to be off to get at the round window in front of the RF mirror... this has a pair of spanner slots, you rotate it until the vertical alignment is right. You will find that you have upset the lateral alignment by doing this, so you have to adjust that afterwards by means of the screw next to the big front window.
I describe the arrangement in the FED-3 part of my zorki/FED page http://rick_oleson.tripod.com/index-58.html ... the difference being that with the FED, you can reach the adjustment from the outside, where in the Zorki the top has to be off.
