I vaguely remember reading that some series-E lenses were not released in Japan, or not at first anyway. The 28mm might be one of them. That might explain why they are not common in Japan.

Edit: I just saw that you wrote exactly that in your blog! :o :o :)

Also note, the early AF 28/2.8 uses the same optical design, but the coating are much better.

The Series E prime sold in Japan are 35/2.5 and 100/2.8.  Nikon EM (and FG) came with Ais 50/1.8 "pancake" without the rabbit ears, not SE 50/1.8.

If I remember correctly, the optics of SE 28/2.8 was also used for the ground-only lens for Nikonos cameras.

Thanks! I almost forgot about that :o :o :o
that was the reason why the early 28/2.8AF got such a bad reputaion ::)

i just checked mir.com and it seems that they're not aware that there are actually 2 versions of the AF-Nikkor 28mm f/2.8D :o :o :o

it's easy to identify the versions, the later, better one has a bigger front element ::)

A little of Topičov; does the AF-D version have the same optical performance as the AIS version? I just bought the AIS and I must say that I’m really impressed by its performance, really impressed! Just like the AI 105 2.5, it perform very good on the D850.

According to Rolands website the AiS has CRC, and a more complex construction.

It has close focus to 0.2m and uses 8 elements instead of the 5 of the simpler versions. For the near and not-too-distant range it's an excellent performer.

The original Nikkor-H 28/2.3 has 6 elements in 6 groups. Although a modest lens by modern standards, it was the first successful wide-angle 28mm lens for SLR cameras and helped them to become the general purpose camera system over rangefinder cameras. You can read about it here: https://imaging.nikon.com/history/story/0012/index.htm.


It was followed by the K (New Nikkor) 28/3.5 which has the same optics with some refinements that allow the close focus limit to be reduced from 0.6m to 0.3m.

In 1977 it was replaced with an all-new AI 28/3.5. The optics are completely revised but remain in a similar 6/6 element layout.


In 1974 Nikon released the slightly faster K (New Nikkor) 28/2.8. This lens focuses to 0.3m without CRC. This lens features a more involved 7/7 element design, but if you look closely the general arrangement of lenses is similar to the original 6/6 design, except the second concave element is replaced by two concave elements:


the K 28/2.8 was upgraded to AI in 1977.

In 1981 the AIS 28/2.8 was introduced, this has an even more sophisticated optical design, now with CRC and focusing to 0.2m. Again, if you look at the optical design, you can see it is really a further development of the AI 28/2.8, except the thick middle element is now split in two with CRC applied across the gap:


The cheaper Series-E 28/2.8 was introduced in late 1979 with a simplified 5/5 optical design. The first AF 28/2.8 (narrow plastic focus ring) and the AF 28/2.8 new (rubber focus ring) have the same optics. These all focus to 0.3m


The AF 28/2.8 D has a new 6/6 element optical design. It focuses to 0.25m without CRC. The arrangement of lens elements is very similar to the original Nikkor-H 28/3.5. Performance is reported to be much better than the older AF designs, probably similar to the AI 28/2.8 but not as good as the AIS version:

The AIS 28/2.8 is also among 1001 nights:

Also the AFD 28/1.4 is described. It is still a quite expensive lens at the used market.

Thanks, Birna and MEPER.

Yes, it’s an exellent performer, indeed.

It’s sharp at F/2.8, even in the edges, and one can include the sun without any flare. Impressive.

I’m not good at focusing manually through the OVF, but with LV magnification it’s easy to nail focus (I dont find focuspeaking that easy/presise either).

What a build quality these MF lenses have!
