I take it we treat the original UV-Nikkor and the Rayfact UV-105 jointly in this thread? For all intents and purposes they are the same lens.

My guess is that possessions by UVP members represent a sizeable fraction of the UV lenses produced.I have two of them and believe not the only one stocking up on the UV-Nikkors.

A characteristic property of the UV-Nikkor/Rayfact is the focusing collar goes way "beyond" the infinity mark, and the red IR dot is on the opposite side, i.e. to the right, instead of the usual left-hand side position of nearly all other lenses.

The UV-Nikkor is also a simple lens to "chip" (CPU-enable). Which is a very useful feature when you do experimental UV work and need to ascertain exposure data. However this will only work with the lens mounted on F- or Z-system cameras.

Your copy is AIS as it has the groove near the pin lock and an orange 32. I think I saw some might be before AIS.

The UV-Nikkor was released years after Nikon had introduced the AiS aperture operation on their lenses.

Thats really good to know. Then other one I saw would be a fake. Thank you. I will watch out for that.

According to my sources, Nikon released the UV-Nikkor 105 in 1984. So it always has been an AiS lens.

It shares the outer casing with the Micro-Nikkor 105mm f/4 up to the 'nose' of the latter, which has a retractable lens hood built-in that the UV-Nikkor lacks. Thus I guess any fake 'UV Nikkor' might be a relabelled Micro 105/4.
