    In order to make sure a lens covers an Ultra-Large Format, you need to first know the length of the diagonal of the format.
    Then, if you have the coverage of the lens, also known as the size of the image circle, you can see if a lens covers a format.

    I know I have multiple lists that show just this. When I get back from oregon I will post them.

    That works well with well documented lenses, like newer ones and "collectibles" like old Dagors. There is a very good list at http://www.mamutphoto.com/content/view/92/43/lang,en/

    I have a few good reference books especially for older German lenses.

    It looks like my technique is to buy the lens, then see which format it will cover. That works too, at least if you have enough cameras...

    Hi darwinwc -

    A good inexpensive lens is the Nikkor 300 f/9 - it covers 7x17 and 8x20. Also the APO Germinars are great lenses - 450mm, 600mm, 750mm and 1000mm. The first two will cover 12x20 and the second 2 will cover up to 20x24. Also the 355mm f/9 G-Claron will cover 12x20 and so will the newer 210 Super Symmar XL (very expensive). Hope this helps.

    Fred

    The Nikkor-M 450mm F9 will also cover up to 12x20 format and produces very nice image quality.

    A 19" Dagor will cover a whole lot ;-)

    It might illuminate these formats, but if you demand optimal sharpness, you should not use it beyond 5x7". What you suggest is MUCH larger than what the lens was designed for. Of course, if all you want is contact prints, you might not need 20 or 40 lp/mm.

    It would make a very good "long" lens for 4x5".

    The circle of illumination of the 300mm f/9 Nikkor-M is large enough for 7X17. However, performance is not real crisp on the corners. The 300mm f/9 G-Claron is a much better lens for 7X17 and 8X20 in my opinion.

    Coverage information provided by the lens manufacturer, and what you see in many charts, is nearly always based on, 1) use of the lens at f/16 or f/22 and, 2) for projection printing where an enlargment of 4X-10X is anticipated. In ULF work we usually think of coverage in terms of contact printing, i.e. no enlargement, and use of the lens at f/45 or f/64, which with many designs increases the useful angle of coverage.

    If you were to rely solely on the charts you would have no idea that the 450 Nikkor-M covers 12X20 with many inches of movement, or that the 355 G-Claron covers 12X20. But both of these lenses are very popular with users of this format. The same is true of many other lenses, so if you want to know if a given lens will cover your format, beteter to ask someone who work with the format before wasting your time with the charts.
