More from the Ikonta. You’re getting some good results from the 521/16. Which lens does it have - 75/3.5 Tessar?
I have a 533/16 and in addition to severe spacing problems (sometimes will wind through a whole roll, not engaging the auto-stop) that 80mm f2.8 lens is very soft by today’s standards.
Thanks. Yes, it has the Tessar. I took it completely apart, cleaned the elements, and collimated it. I have been working on about a dozen folding cameras for months. I've given up on problematic spacing and started removing the extremely dark red plastic frame counter windows. One was almost completely opaque. On these old Ikontas none of them control spacing, just shutter locks. Since each frame is a different amount of film advance turns - the only way to be sure is the printed paper back markings. I just do it in subdued light.Also, none of these old lenses are sharp wide open - So I stop them down to f8 or f11.
