    Looking for a 14-15" (360mm) lens in barrel that easily covers 15" film

    Any recommendations?
    My format will be 8 1/2 X 15 (or there abouts).
    Due to the constraints of my modified camera back, 14" is about the shortest lens I will be able to use focused at infinity.
    No shutter needed, can be a repro or enlarger budget priced lens.
    The 355 G-Claron may work, just wondering if there are any other options...like:

    Rodenstook APO-Gerogon 360mm F/9
    CZJ Apo-Germinar 360mm f/9
    Rodenstock Apo-Ronar 360mm f/9
    Schneider Componon 360mm f/5.6
    Schneider 355mm Repro-Claron f/9

    Randy, for years I've used as my go to lens for 8x20 the Rodenstock APO Gerogon 360mm F-9 lens. It takes 77mm filters and is sharp as all get out. Still a bargain if you find one. Also small and light weight. It stays on the 8x20 all of the time.

    Try a 14" Commercial Ektar. Coverage is in acres.

    To echo Jim, a 360 Apo Gerogon will do. But remember that its cells aren't direct fits in any shutter. Apo Ronar and Repro Claron won't cover.

    I guess, price wise - and perhaps performance wise, the Rodenstock APO Gerogon 360mm may be my best bet. Just have to wait for one to come available.
    I have a B&L 1C 11X14 that looks like it may cover, especially at f/22-32, but it is such a large, heavy lens.
    I have a 45cm Apo Nikkor that will work nicely - I was just hoping to come across something a tad wider.
    Thanks for the input.

    I saw it Jim - looks like it doesn't have a retaining ring and I don't see any aperture markings on it - but I am thinking I may have a problem with that type of lens - since my Packard shutter is mounted right inside the front standard (behind the lens-board) the rear element of the lens may prevent me from using the shutter. That would call for more modifications..

    Randy, I just took a look at R'stock's Apo-Gerogon documentation. You're right, the 360 is wasp-waisted with the mounting threads far in front of the back of the much wider rear cell. That's no reason to pass on one.

    What you need is a disk threaded internally to fit the mounting threads and externally to screw into a tube slightly wider than the lens' rear cell. The tube would attach to the board. I'm not sure how much a machinist would charge to make the bits, but you might want to look into it.

    Not a my idea or even a newish one. That's how the Horseman TC attaches to a lens.

    Randy, I looked at the documentation again. The 360 Apo-Gerogon's rear cell is threaded M58x0.75 internally. I don't know whether you're up for the added expense, but I have several aerial camera lenses, one quite heavy (12"/4 TTH) that are held to boards by adapters that pass through the board and screw into the back of the lens. The board is clamped between the adapter's rear flange and the lens.
