Durst Laborator 54 question

Discussion in 'Darkroom Developing and Printing' started by leandronatale, Jan 31, 2005.

  1. Hi. I recently purchased a Durst Labo 54. The setup had all th
    condensers, but lacked any lensboards.

    The manual doesn't explain what lensboard is available for each foca
    distance, so I did some research. My findings were the following:

    - Latub for small format (50mm).
    - Seriopla for medium format (80-105mm)
    - Lapla or any flat lensboard for large format (150mm)

    Is this correct? I am specially interested in the 50mm and 105m
    lensboards, since my actual equipment is a 35mm and a 6x9.

    Another question: are the newer lensboards compatible with my olde
    durst? I ask this because it is almost impossible to find a Latub i
    Argentina.

    Well, thanks for listening. If you have any ideas, feel free to jum
    in.

    Greetings,

  2. AFAIK Durst uses the same lens boards for about 50 years now. These are
    round disks with about 70mm diameter and a bevelled edge. The main
    portion of the disk at the rim is about 8mm thick. There are several
    variations of this scheme (flat, recessed and protruding). The Latub
    looks like a can of preservatives with a rim.

    It really depends on the minimum distance between the lens board and the
    neg holder and the focal length of your enlarging lens what kind of
    board you need. I can use a flat board with a 90mm Apo-Rodagon in my
    L139 (way larger than your L54) and need a deeply recessed board for a
    50 or 60mm lens. AFAIK Durst still manufactures the L1200, so the lens
    boards should be available new. However, it would be easier to scan
    ebay.com and buy a few used disks, they won't get bad and its better to
    have a few spares handy. These things come in several variations and
    threads, but most are M39. Buy what you can get, there wil be a 5.6/150
    Rodagon in the future (for 4x5") that needs a 50mm thread...

  4. I had one for several years.
    Correct. The Latub 2 will also couple to the aperture ring of older
    rodagons or componons 4/50mm but not any lenses with larger diameter
    i.e. anything current.
    Seipla 75 is the one sold for lenses from 75mm up when your 54 was
    factory new. The Siriopla is a bit shorter and may suffice for 80mm and
    above.
    The Lapla is usable from 100mm up.
    You need a Latub then.
    Lapla or any of the above with limitations (aperture-ring hidden inside
    a tube).
    Yes, as long as they share the same diameter. The current Siriopla,
    Siriotub and Neriotub should also fit and are avaible for much less as
    they are made from moulded plastic. The Neriotub is the deepest
    lensboard still available, made for 35mm lenses on an M805 and it *may*
    be an alternative for 50mm lenses on the 54 if you can't find a Latub
    but I'm not sure if it is deep enough.

    OTOH: The 54 has quite a long column and you may be able to print even
    35mm as large as you like with a 75/80mm lens untill you find a latub.
    It all depends on what format you prefer for your prints.

    best
