Thread: Lens to cover 20x24

    Lens to cover 20x24

    I am trying to build a 20x24inch camera just for a fun project. I have found Wisner's website fairly informative about which lenses will cover 20x24 inches but can't seem to locate any of those lenses. Any ideas? or any other information about building a camera this big? Thanks.

    There's a frighteningly large lens on feebay right now that will cover 60x80 inch film. That should give you some movements

    Try looking for a 19" Dagor, they come up fairly often but of course are not cheap. Also the 19" f"11 wide angle process version, very rare.

    I'm sure you are aware of the Schneider XXL lenses with the 900mm image circles, which you can purchase new for a large sum of money, but there are still many more old and new process lenses available on ebay and other online sources. There are also many experts out there, such as Kerry Thalmann, Jim Galli, Ole Tjugen, Arne Croell, etc. who check in here regularly with lens info. Check the archives here and on APUG for 20X24 topics (and of course the classifieds in both). www.mamutphoto.com has a lot of ULF info, as well.

    There's a 600mm f/11 Fujinon-C on eBay right now. No relation, interest, yada^3.

    Quick! Buy the 30" Artar that WFWhitaker is selling for $350 on the FS area here!

    The 600mm Fujinon doesn't cover 20X24 at infinity and the 30" Artar is "iffy" according to the seller, but perhaps the 35" or 42" would work.

    You need about 790mm of image circle for a 20x24. The published specs for Artars are conservative. The Goerz catalog states the 30" Artar will cover a 16x20 plate with a prism and approximately 15% more without the prism. Coupling this with stopping the lens down to f45 or less should cover 20x24. You may want to contact Tracy Storer to learn his experience with the 20x24 Polaroid. The Mamut web site will give you a wealth of information. Good luck (and William has a fair price for that long Artar).

    I just found Ron's chart for 20x24 and it lists the 30" Artar as usable. I'd seriously consider William's lens. For an experiment, the price is right and you'll not lose value if you decide to sell it later.

    I have a 17X20 Gundlach Symmetrical. It's 26" combined and I believe a triple convertible. So that would be something like 26" 45" and 60" or some other crazy numbers. All the old lenses would cover a plate larger than the advertised when stopped down so I would bet this one will cover 2024 easily. I offered it a couple of months ago for $650. Our friends in Asia are snapping up all of these antique US BIG lenses about as fast as they hit ebay.
