I recently got a super Ikonta 6x9 on ebay that I have probably over paid at $400. I found lots of light leaks on the first roll. Fortunately there is someone dedicated to repairing this old cameras.
Mine has the Carl Zeiss Jena tessar 105 mm. 1:3.8. I have looked at the slides I shot with it with a 4x loupe and I have to say that I am very impressed with the sharpness and contrast even though all of the shots were handheld.
Now I am considering fixing this one and keeping it forever. It is a great little thing that just slips easily into a pocket or funny pack and will let you take all the great shots you would have missed by leaving the big cameras at home.
