I was working in a lab and we used the Micro Nikkor 55 f/3.5 as a reproduction lens for duplicating slides, it was very good at doing that. A couple of times I borrowed it for weekends, it became a much loved lens, but probably wasn’t that flash on infinity subjects, but still quite good at infinity.
The faster updated version the Micro Nikkor 55 f/2.8 was released in Australia around December 1979 I tried one and bought one for myself. It came with the PK 13 extension tube which enables you to take 1:1 images, although the front of the lens is perilously close to the subject when doing 1:1.
For a couple of years this was my take anywhere lens as it gave super sharp images pretty much for everything; the other reason for taking it everywhere was quite simple, it was the only lens I had for my Nikon body; I was switching from Pentax to Nikon.
The sharpest and best of anything I have shot in 35mm land, has been with the Micro Nikkor 55 f/2.8 and a very good tripod on FE2 and F3 bodies.
At f/5.6 to f/8 it is in another league to almost anything I have ever used. Add the sturdy tripod and the lens is so sharp it’s a wonder it doesn’t cut the film.
I bought my 55 f/2.8 lens brand new, it was never abused but it was worked very hard for about 10 years, then it was used far less as I had other Nikkor lens available. I did find on one extremely hot day, a bit of a problem. I had been shooting in portrait mode with a tripod and started to get shutter sticking, or so I thought. Turned out the lubricant on the helices had started to run into the aperture blades and gum up the works. I had the lens pulled apart and given a service and it has been good as gold ever since. I have heard these lenses do have this issue, so beware that you may require a service on one of these units.
The next best lens for sharpness and resolution I personally have used in 35mm land, is the Nikkor 85 f/1.4. This lens works extremely well at f/1.4 but is decadently sharp from f/4 to f5.6 and a half.
There are others, but these two are the stand out performers in my armoury of Nikkor and non Nikkor lenses.
