The lenses I put on one of my FED 2's reads approx. 1.1 meters for a 1 meter object to be in focus. I've checked "register distance" with a depth micormeter and it's within 28.78 to 28.82 mm. I know the lenses aren't the problem cause I've tested tbem on a camera I know is spot on.

Now I'm going to attempt to adjust the rf sensor head. The problem is I can't seem to budge it. Is there a trick to it? Any help would be appreciated. :)

P.S. I was following the instructions on the FED 1 & Zorki 1 Survival Site.
 
I've done it. I was thinking to myself, "It no good to me anyway if it doesn't focus properly". So I just torqued it. Woo hoo! Now it's spot on. Time for some test shots. :)
 
I turned the teardrop shaped head on the arm within the body. Is there any other way to adjust close-focusing distance?
 
I'm sure that's not a good way to do it, although I can see that it would do the job.
The horizontal alignment is done by turning a small screw hidden under the chrome headed screw between the rf and view glass. The vertical alignment is done by turning the prism which is clamped under the rf window bezel. Note that large adjustments in the vertical can affect the horizontal, so vertical first. There is a good link to some pics for this, I will have a look.
Of course! it's very well covered in the sticky thread at the top of this group. Didn't you see it?

The screw adjustment in the Viewfinder is mostly for aligning infinity adjustment. The "Teardrop" cam appears to have been made entirely for the ability to adjust the rangefinder at close-focus distance. Simply adjusting the screw can bring the infinity adjustment into view, but the close-focus distance can still be way off. Also, for an adjusting target for close-focus, try using a pen and ruler to make a thin-line cross hair on paper (+) ... makes it easier to check horizontal and vertical at the same time.
 
The adjustment under the screw will adjust near focus and infinity alike, however
I see that turning the shoe would give a differential adjustment. Last resort though?
 
Well, I turned the "tear drop" shaped thing and that did the trick for me. I tried adjusting it the conventional way but it didn't work.
