The Nikon Nikkor 55 mm f / 1.2 Ai is a normal ultra fast prime lens for 35 mm SLR Nikon F cameras.
This is the last release of this really legendary lens (the rest - without Ai-connection). Serial numbers 400001 - 425518. It was manufactured since April, 1977 to April, 1978, that's why it is rather rare and finding one may be considered a success.
The Nikon Nikkor 55 mm f /1.2 AI lens produces wonderful bokeh (background blurring), which is result of great lens speed ( Nikon never produced serial lenses with greater lens speed).
It is made from metal and glass - a really durable build. It is perfect for portrait photography - soft when wide open. When stopping down, the Nikon Nikkor 55mm f /1.2 Ai lens is rather sharp and is suitable for other types of photography.
Remarkable feature:having used for some time the Nikon Nikkor-S 55 mm f/ 1.2 non-Ai and the Nikon Nikkor 55 mm f/ 1.2 Ai, which at first sight have no differences (I have even compared the travel of focus rings), I found it much more difficult for me to shoot with the non-Ai lens - inaccurate focusing, more defective photos ... I can't find any scientific explanation to the fact, it just happened like that... Besides, the non-Ai lens I used was quite normal, without defects, and some pictures I had taken with it were all right... As a result, I have kept the Nikon Nikkor 55 mm f/ 1.2 Ai, though objectively I can't say any bad things about the Nikon Nikkor-S 55 mm f/ 1.2 non-Ai ... I somehow didn't get on with it...)))
