240mm-260mm f10 Nikkor Process Lenses for 8x10 Enlarging

[neil poulsen]

Has anyone used the 240-260mm f10 Nikkor Process Lenses that keep showing up on EBay for enlarging 8x10? The f10 are the wide-field lenses, probably double-Gau sses. Or, has anyone used these lenses in any focal length for enlarging? If s o, how do they work? Would they give sharp results?

I'm referring to the Apo-Nikkors. Also, has anyone used the non-wide field f9 240mm-260mm Apo-Nikkors process lenses successfully for 8x10 enlarging.

While I haven't used mine for enlarging (yet), I've been using my 240mm f/10 Nikkor as a taking lens on my 8x10 for a few months now and everything is absolutely tack sharp, including some stuff shot at 1:1. I imagine that they would give equally sharp results when used for enlarging. If I get a chance to test it as an enlarging lens, I'll pass the results on.
