I'm trying to fix the rangefinder on a Super Ikonta B, 532/16. The image moves diagonally instead of horizontally. I have cured the same problem on a Super Ikonta C by reference to Dantestella.com information, but the 6x6 camera seems more complex. Can anyone suggest the source of a manual or offer any suggestions? My main problem is how to disengage the lens from the RF assembly so that I can set infinity focus through the rotating wedges without the lens turning. Many thanks, |

It has been awhile since I did one of these but you have to take the front cover off to disengage the lens from the rangefinder. They are a bit of a pain but they are nice cameras when they are working correctly. Regards, Roger |

Roger, Many thanks for that information. I can now see how to disengage the drive to the rotating wedges. For my next trick, I'll have to work out how to remove one of the wedges so that I can turn it a little at a time until both images are at the same height. Regards, Leslie. |

You will get it with a little patience. I have one waiting for a rainy day. It has another problem in that the rangefinder needs to be recemented. I don't have the cement so it will be awhile before I get around to it...Roger |

Roger, After much adjustment, a gearwheel tooth at a time, I managed to align the wedges correctly and the moving image is now perfectly horizontal. BUT I now find that one image is higher than the other! Presumably that means a fault, or possibly an adjustment, in the prism that would have to be accessed by removing the top. Does your comment about recementing have relevance here? Once again, my thanks for your help. Leslie. |

The Super B uses a prism to split the beam. I don't think its possible to recement these so easily because there is also semi reflective gold in the cemented joint. In any case it mucks-up the brightness/contrast of the image, not the vertical alignment.
I had a slight vertical misalignment on my Super B. Best I can tell, there is no adjustment. It may be from the lens standard not erecting to exactly the correct spot. |

The beam spliter is glued with Canadian balsam I believe which degrades over time. It is the major fault with the viewfinder on these cameras in their old age. This would not have anything to do with the vertical alignment though.
You may be able to change the vertical alignment by shiming the beam splitter. The top would have to come off of course. |
