420 Apo Nikkor & 480 Apo Ronar

[Pete Watkins]

I've just won these two lenses on the E-Bay U.K. auction site for a silly amount (£28-99). I can find a bit of info on the Apo Ronar but nothing on the Nikkor. I have no doubts about the quality of these lenses but the two main questions are 1) Can shutters be fitted easily? I have Packards and LUC's if needs be. 2) Will either of them cover 11 x 14?
Thanks for your time.
Pete.

The F/9 Nikon? Packard time. Memory tells me 55 or so degrees of coverage. I think it'll just cover 11x14. Contact printing even more I guess.

There is a different version F/10 I think but I don't remember.

Should be plenty of info on the Nikon here.

I have a 420/9 Apo Nikkor. It is a dialyte type. Nikon's data sheets claim that it covers 46 degrees, 350 mm at infinity. Fine lens.

Pete, you might be able to hang a LUC in front of one or put one in front of a Packard. Actually putting one in shutter is a large job, possibly not feasible.

Nick, about that thread you pointed to. It contains a comment to the effect that the tessar type Apo Nikkors antedate the dialyte type. Not so, the two types were made simultaneously. Nikon claims the two types were made with different applications in mind. The tessar types have much narrower coverage (150 - 300 mm, 45 degrees; longer ones, 37 degrees) and, Nikon claims, higher resolution over that narrow field than the dialyte types (46 degrees up to 610 mm, longer ones 42 degrees).

I thought it was the F/10 that were wide? Except for the long ones the F/9 are Tessars. So that's wrong?

Yes Nick, that's wrong. My data sheets, which are incomplete, list 240, 360, 420, 480, 610 and 760 as dialytes; 150, 210, 300, 450, 600, 750, 900, 1200, 1800 as tessar types. All f/9 except the 760/11 and 1800/14.

The f/10 Process Nikkors are 4/4 double Gauss types but are in no way wide angle lenses. Wide for process lenses, yes, but not as wide angle lenses go.

I have 305 (not mentioned above, dialyte type), 420 and 480 Apo Nikkors. All very good. Also a 260/10 Nikkor-Q (4/4 double Gauss just like the 260/10 Process Nikkor and it looks like the PN too) on which the jury is out. I prefer my 10.16"/9 Taylor Hobson Copying Lens (originally made for Haloid Model D/Xerox 1385[this # may be wrong] variable magnification copiers) to it, much smaller and lighter, seems a little sharper.

Cheers,

Dan
