Process lenses DO count as enlarging lenses, because these are precisely what many high-end enlargements are made with, and have been made with, in one fashion or another, for a long time. And many of these lenses were designed for more than one application to begin with. It's not my fault if some people are apparently unaware of that cross-marketing fact. Print shop suppliers sold apo lenses for process camera use, while certain pro photo houses sold the VERY SAME lenses to the big photo labs for enlarger applications. The irony is that, in certain focal lengths, one can now find extremely good used process lenses at very reasonable prices compared to what they once sold for, and which excel at enlarging, even better than ordinary enlarging lenses.
Rodagon G's are specialty lenses made for high magnification - very big enlargements, not for general use. Like I already mentioned, certain Apo Nikkor have also been used for that same purpose. For medium format negs, I really like Apo Rodagon N lenses. I have both a 105 and 150. The 150 also works for 4x5 of course, though I often use a 180 regular Rodagon instead. My Apo Nikkors run from 240 to 760mm, though I never use the longest ones; they simply came with the set I cannibalized from a huge process camera (22 ft long).
But I have uses for certain regular El Nikkors too. For example, their cheapo 75/f4 version is a lousy MF lens, but works wonderfully for 35mm. The 360/5.6 is nice and bright for composing and focussing color neg film with that darn orange mask, but a draft-horse sized lens, and not quite as critically sharp in the corners as an Apo Nikkor. But since even a 30X40 inch print is only a 4X linear magnification from 8x10 film, there is almost no visible difference in the resultant print itself.
