Well, at least I do hope it is good for UV applications !! The optics are dating from early '60s, there is no multicoating and only 4 elements, and none of them are cemented. Filters can be added to the rear end of the lens head yet are protected inside the focusing barrel. All of which taken together is a promising starting point for some severe UV work.
Here is the 400 mm f/4.5 Nikkor-Q with the focusing adapter CU, complete with boxes etc. The price was ridiculously low probably because the less fashionable CU focusing adapter is part of the assembly. However that will not bother me as I already have the more modern AU-1 unit ready for the new lens head.
The lens is currently in transit so will arrive in a week or two ahead, unless the Norwegian Customs throw their usual spanner into the works. Then days fly by before the item has cleared customs.
The reason I like to put this long lens, incidentally not a telephoto design just a long focal length unit, into service for UV and/or IR is the available long lenses for UV are scarce as hen's teeth. UV extends beyond documentation of botanical subjects, however nice these appear in UV.
(and yes, I already own several genuine UV-Nikkors so no need for more of them)
