I'm sure Klaus knows a lot about it...

Yeah, it is only for curiosity that I posted it here. I don't recommend you buy it! Wink

Had three of them, sold them all over time and bought really useful macro lenses for that money Wink
More a collector's item than a useful lens IMHO esp. since it is NOT color corrected.

"Klaus, auf dich ist Verlass!" Very Happy

28mm macro lens? Bet that has a pretty short working distance, one thing I've learnt lately is really short working distances are a PITA to illuminate.

May I kindly propose to also read a book about optics maybe some time - it helps a lot about understanding the basics... Wink

And it is not a "macro lens" in the classical sense, it is a highly specialized lens for micro reproduction of computer chip structures, used in the beginning of microchip production (436nm was the 2nd generation after 546nm lenses - today it is DUV up to 193nm).

Why would a "normal" macro lens have f1.8 speed?

Please don't patronise me, I asked a question, I had no idea it was not a normal macro lens, I have never had any interest in microlithography so was not aware of the optics used.

Why would any lens have f1.8 speed? I don't understand your question.

It is not important to understand the principles of optics in order to take photographs any more than it is important to understand the principles of the internal combustion engine in order to drive a car.

I thought the purpose of this forum was to share knowledge so that members may further educate themselves, I wasn't aware there was a required level of education and readin in order to participate in the discussion.

Far from patronizing anyone. It was a well-meant proposal so as to understand some optical basics better - isn't that what such a forum is for, to gain more knowledge?

I had quite a fantasy concerning this lens earlier this year. On an auction site, where the owner clearly did not know what he had, I bid on six of these. Yes, six Ultra Micro Nikkors. Apparently they come as a set; three of them like the one posted above. Each one had a "steel" case for protection, and these six steel cases fit in a velvet lined wooden box.
I bid $75 dollars, which held as the highest for a number a days. In that time I researched the internet and found very little information. Only two photographers (that I found) had fashioned a means to use these on their cameras (reversing them and using either a bellows, or tubes). I believe that they have M39 thread mount, but their flange distance was quite short (20mm?). So, I began to wonder about their use on a SonyNex.
I did read that the resolution of these lenses was extraordinary (800 lpm) and there is absolutely no distortion.
But, sadly, as if often goes, the knowledgeable bidders waited until the final hours and the winner paid $4,600. My dreams of a Caribbean vacation were dashed. Sad
