Rodagon or Componon-- can only keep one

    I've managed to acquire both an older Schneider Componon 80mm f5.6 and a
    Rodenstock Rodagon 80mm f4. I'm gonna sell one and keep the other if/when I
    pursue medium-format photography.

    The Componon is older with a shiny metal housing. It has about 18 aperture

    The Rodagon appears newer and is lighter in weight (plastic). It has the
    click-stops that can be disabled.

    Both lenses are in good shape although the Componon has a very very slight
    amount of haze whereas the Rodagon just has the normal amount of internal

    Of course I'd compare them side-by-side with prints from 35mm negatives
    however the Componon is already mounted in a lens board and the Rodagon
    doesn't fit in the hole if I try to swap them (I don't think the Componon is
    the standard 39mm size). Thus I'd have to acquire a lens board for the
    Rodagon. Therefore if these lenses are about equal in quality, I'll just
    keep the Componon for this reason.

    I have no personal experience with these lenses, but do a Google goups
    search for:

    enlarger lenses

    There's a test made by a German magazine on enlarger lenses.

    The Rodenstock is a newer design, larger aperture, better coating, and
    covers 6x7 negatives.

    The Componon only covers 6x6 according to the manufacturer. The Rodagon is a
    slightly wider angle of view.

    All of the above, and the haze noted, I would keep the Rodenstock.

    The Componon S is the Schneider lens that competes with the Rodagon. The
    Componon is inferior to both the Rodagon and the Componon S.

    Also besides having disengageable click stock the Rodagon also has a
    illuminated aperture ring and a pre-set aperture.

  6. Poor baby:) The Rodagon is probably the better of the
    two but probably not by very much. I have one of these guys
    and its very sharp although my much newer Componon-S lenses
    are sharper at larger stops. The haze can be cleaned out.
    The retaining rings have slots on them so are fairly easy to
    remove. This haze is common in older lenses and wreaks havoc
    on contrast. It comes off with any standard lens cleaner or
    widow cleaner, the problem is getting at the surfaces.
    I like the old style multiple blade iris. Newer lenses
    have plastic blades and fewer of them. They probably have a
    subtle (?) effect on the image quality.
    My suggestion is that you have a good look using a high
    magnification grain magnifier to see what both lenses do at
    various stops.
