Zeiss Ikoflex IIa, Teronar Desyncronized!!!!!

Hi all!

the viewing lens (Teronar) on my Zeiss Ikoflex IIa is desync with

tessar!!!

I suppose that it has to be recalibrated.

the Teronar viewing lens appears to be too backward (and bypass the

infinite at 4m on the knob!!!!)

Please Help me!!!!!! and excuse my english!!!!

Thanks!

First you should check whether the taking lens (Tessar) is still in correct focus. I don't know how to correct this on an Ikoflex, on some other TLRs it is done by placing shims (washers) between the rear shutter collar and the body.

To recalibrate the viewing lens (Teronar), on most TLRs you will have to remove the fold-out viewfinder and the focussing screen. Usually the viewing lens is held by a screw ring which secures the thread of the lens mount. Loosen it, attach the focussing screen again and turn the lens until it is in focus. Then tighten the screw ring again.
