Help with the Industar-61

[p.giannakis]

Hi everyone!

I bought a FED-4 with an Industar-61 a couple of weeks ago. Today i put the industar on a Leica IIc and i focused on an object 2 meters away. The industar showed 1.5m on the Leica but 2 meters when put on the Fed. I put the Elmar on the Leica and it showed 2 meters too. (!)

Is the industar compatible with the IIc's rangefinder? Any suggestions as to what is gong on?

Thank you.

The FSU lenses are not made to the Leica standard. You can shim the lens to correct most of the error.
