    If someone gave you a lens...

    ... in this case, a Process-Nikkor 260mm/10 lens, what would you do with it? It's a bit dirty, but the optics and aperture look nice. It's in a Robertson mount (I think it came off a camera for reproducing plates for printing newspapers).

    So... any good ideas of what to do with this lens?

    I'd clean it fix it to a 10x8 camera lens board and test it with a shutter. I've some larger Thornton Pickard shutters that would work with a lens like that, may have to be mounted on the shutter which is attached to the lens board, that give Time and Instant speeds 1/15th to a 1/90th

    May depend how the lens is attached to the Robertson mount.

    I'd make a lensboard to fit it and strap it on my Calumet cc-401 and start shooting. Probably make a cap for it to use as a "top hat" shutter. If I didn't already have a LF camera I'd make one quick.

    What's a Robertson mount?
    The best I could find on the web was a bagpipes joint!
    Is it like this?

    I occasionally use a Fujinar 250 for enlarging 8x10, so if someone gave me that Nikkor, I'd use it for enlarging 8x10.

    Funny you should ask. I have one, also Nikon's f/10 Process Nikkor catalog. I spent pots of money at SKGrimes for an adapter to mount it in front of a Copal #1. This, alas, before I found the catalog.

    Per the catalog, the lens is not an apochromat and is not suitable for use outside of the recommended range of magnifications. Apo-Nikkors (so badged) are apochromats and are suitable for use at all distances.

    The 260 Process Nikkor is recommended for 1:3 to 3:1. It is symmetrical so doesn't have to be reversed when magnification crosses 1:1.

    I bought the mount adapter so I could find out what my lens was good for. I've shot it at distance. Short answer, not much. If I were you I'd invest nothing in making it usable.

    Small enlargements, maybe up to 3x. You'd be better off with a 305/9 Apo-Nikkor.

    Dan, it's rare to see someone sharing my thoughts on process lenses.

    One problem is that if you test them with a lens chart they'll out perfom other lenses because that's what they are designed for - copying flat field artwork, but in real life conditions particularly towards infinity they fall behind quite rapidly.

    Small magnification but big enlargement 24x30" I couldn't even process a print made at greater than 3x.
