    Hi!

    I just bought this lens, I still have to get my hands on it

    it was made by Hermagis Paris, it's an "Extra Rapide" no.4

    it should be a portrait lens (petzval?)

    it has a diaphgram iris with aperture range from 3.5 to 20

    the barrel diameter is about 9 cm and about 20 cm tall

    it comes with a mounting flange and a hood (about 10 cm diameter)

    I didn't find any information on this lens on the web... how old do you think it is and which image circle do you think it covers?

    I will probably answer the latter question myself once I have the lens here, but I would still like to know more about the lens, I'm not an expert, but was looking for a very old portrait lens... I hope it will cover the 5x7 format and hopefully full plate or 8x10

    thanks

    Better post a photograph of it when you get it, might get you more responses.

    the focal length is likely to be around 300mm, meaning that it covers 4x5" SHARP. Or 8x10" with lots of swirl...

    Hermagis was a French maker of optics
    from about 1860 to about 1935, according
    to the Vade Mecum. I have a Hermagis
    "Objectif pour Portrait N. 6" -- it is the lens
    you see in my avatar. The name of your
    lens suggests a rapid rectilinear design, of
    which Hermagis made many. But the
    apertures you mention are the same as
    the ones on my Portrait N. 6, and the f/3
    maximum seems too wide for a RR design.

    The Vade Mecum entry for Hermagis is
    sketchy at best. As you have found, there
    is very little information about the Hermagis
    line on the Internet, but it appears that in its
    day Hermagis was a leading maker of optics
    in Europe.
