For some reason which I can't explain, I have never owned the 105/2,5. To rectify the situation, I have now aquired two of them, both arrived a few days ago. One is an Ai-converted K, the other is Ai-S. Both in mint condition. I enjoy and love using these classic Nikkors more and more, and have a decent collection - 16/3,5 (x2), 20/2,8, 24/2, 28/2, 35/1,4, 50/1,2, 105/2,5 (x2) and 180/2,8 ED.
