    My mistake---it is an Acuton. Just as well; I already have a good tessar type in the same range, but the larger coverage and convertibility put mean this one fills a different niche.

    The lady of the house has to be a pretty swell sort of person to put up with the annoyance of a photographer.

    Well, I shot a couple of smoke tests, and the results ain't bad, at least in terms of the lens's performance. You can't fault it for sharpness, and considering its vintage the contrast seems acceptable; also, the perfectly round apertures are a nice little bonus. The shot of the peppers is quite strongly backlit, and I think the amount of veiling is reasonable considering.

    Both of these are negative scans, and I seem to have had the sloppiest day of my life for tray development---the scratches are outrageous, and there are even some fingerprints around the edges, which is pretty hard to achieve when you're wearing gloves! I don't think the lens can be blamed for that part, though.

    Tessars aren't convertible, some plasmats are. The likely convertible plasmat was Ilex's own 215/4.8 Acuton, said to be a good lens.

    Which were you thinking of? Oh, and by the way, I find Ilex' nomenclature nearly as confusing as Graflex'.
    That one.

    Nathan, re vintage. Per P-H Pont's Berthiot chronology, between 1900 and 1905.
