I've got a jupiter 9 85mm Made in about 1962 I only used it once so far seems fine thats the only russian lens I got for it. I was looking for a nikkor 85mm but I need to find it at the right price. I have nikkor 35mm f2.5 early made of chrome and brass I bought with a contax iia I also got a 135mm nikkor "c" with it. I have two f2 sonnar 5cm optons one nickel f1.5 sonnar and 13.5cm sonnar and I have a iia body thats been cleaned works fine
