Please illuminate me. This 55 1.2 sc is a non AI lens? So how do you get it to work on a Nikon dslr?
Quite a number of us have been avidly pursuing pre-AI lenses that were made entirely of metal. They have scalloped focusing rings. As Peter and Rafael mention, these older lenses must be converted before they may be used by modern Nikon DSLR cameras. That may be done reasonably inexpensively by having the aperture ring cut down. The more elegant solution, the one that I opted for and that Rafael has done as well, is to find lenses that already have installed, an AI conversion kit manufactured by Nikon some years ago. They are available, as Peter noted for only the less desirable Nikkor lenses.
Lenses with the conversion kit tend to be more rare and to cost more money. Then another wrinkle can be added to the adventure because Nikon changed lens design and lens coatings over time, so there are often a number of versions for each pre-AI lens. Rafael just bought an S.C. version of the 55 f/1.2. He already owns the S version. The C represents multi-coating. Those are the last pre-AI lenses made by Nikon. The AI version of each lens generally has the same optical design and the same coatings as found in the pre-AI version carrying a C in its designation.
We've been sharing the lens owned by Ben in Sydney which is an 85 f/1.8 H.C. AI'd. That makes it the last pre-AI version of this lens and it has the AI conversion kit. I've wanted to buy a copy of that lens but have been unable to find one in excellent condition with the AI conversion kit. I eventually bought an 85 f/1.8 H AI'd. I decided not to drive myself crazy looking for the H.C., though if one comes my way, with or without the AI conversion kit, I might buy it and change aperture rings between my H and the H.C.
The whole adventure is complex but great fun to navigate, especially when one can share it with so many great folks who share a passion for these lenses. Here is a photo of most of my pre-AI lenses, all but one of which has the conversion kit.
