Nikkor 105mm AI-d or AI-S

[Sundowner]

No manual focus 105mm f/2.5 Nikkors focus to two feet unless they have been modified.

Okay, I stand corrected: I just mounted mine and measured the closest focus distance, and it's exactly 29.5"...so, basically two and a half feet, or .75 meters. I knew it was less than three feet, but I was off by a bit. Thanks for prompting me to check that.

In the old days we measured focusing distance from the focal plane mark on the top of the camera. This can add several inches if we include the length of the lens to the mounting flange and the film to flange distance.

I measured from the lens mount. So, add an inch or so.

I have the non-Ai Sonnar type, and it is one of the finest 35mm lenses I have ever used. Incredibly sharp for distance, and a really great portrait lens.

I also have several versions of the Nikon 105/2.5 and, like others have said, the pre-AI Sonnar-type is the best for portraits.

You should see what it does on a Canon dSLR with an adapter.

Makes it produce marvellous slides and negatives?
