The buyer of this lens "traded-up" to one of my F1.5 sonnar conversions. While back in my hands, decided that it needed an "edge". so now it has a 0.75ft Edge over most Leica mount Nikkors. This lens is sold. For sale is a Nikkor-H 5cm F2 in Leica Thread Mount, front element had cleaning marks filled in with eye-glass repair kit, cosmetically EX condition. The infinity lock tab has been removed, and the indent for close-focus has been removed. I modified this lens to retain RF coupling past the normal 3ft for LTM lenses, done by filing the threads down in order that the RF follower wheel of the camera maintain contact with the RF cam of the lens. This lens will focus to 18”, but the RF coupling of the Leica will stop at about 2.25ft The front element had cleaning marks when I got it. I diluted the solution from an eye-glass repair kit to fill in the marks, and the performance of the lens was improved. Keep a filter on the lens, blow-clean, use lens-cleaning tissue only. Do not use a wet cleaning solution on the lens. Focus is smooth, aperture is smooth. The third-party LTM to M-Mount adapter shown with the lens, rear cap, and filter are included.
