Seeking history of Nikkor LF lenses

[Oren Grad]

I don't see the 610/9

The Japanese Wikipedia page is devoted to lenses marketed for general-purpose use, not process lenses. You'll find the 610 in Dan Fromm's article on Nikkor process lenses:

"Process Nikkors" indicated a lower-budget line suitable for stat cameras, much like the abundant Rodenstock Roganors which have been private-labeled many different ways for silkscreen stat camera, budget enlarging lenses, etc. But I've never even seen any kind of Process Nikkor in this part of the world - they were all 4-element Apo Nikkors, originally expensive, or else a few Apo El Nikkors, really expensive. I used a 305/9 Apo Nikkor a few hours ago for an 8X10 color film enlargement. They're remarkable lenses. The dang print looks almost like a contact print, except for being large. But if you need brighter focussing or more speed, most regular f/5.6 El Nikkor enlarging lenses are pretty darn good in their own right. The difference is, the Apo Nikkors are superb all the way from quite close up to infinity; so you can use them for cameras too if you like. But other than a little experimentation in that manner, I keep mine in the lab.
