    Bronica had a fisheye lens for the 6X6 system (SQ) though i am sure it covers at least up to 6X8.

    I use a Rodenstock Apo-Sironar-Digital 35/4.5 on a Fotoman 69. Extremely sharp, and only just covers the 6x9 format without movements. Would not cover 6x12. For a similar ultrawide perspective on the 5x7 format there is the Schneider Super-Angulon XL 72/5.6 which again covers the format, but with little room to spare.

    Thanks; I was not aware of the 35mm Grandagon.

    Re: Is the 47mm the widest lens, period?

    There are some options in formats 35 mm, medium format and large format.

    It's the old series of Zeiss Biogon 38mm, 45 mm, 53 mm, 75 mm and all f: 4.5.

    Zeiss manufactured the model 38 for Hasselblad SWC series (and ALPA series) and then fabricate large format to the other 3.

    I've used 4 and are truly wonderful, just that 75 is too heavy (like a dead cow) and is too big. But they all give superb quality even after many years. A I think they're better than most current wide angle lenses for large format ... but everything is a matter of weight, so use modern Super Angulon.

    For 35mm there are also several Zeiss Biogon (for Contax G and Leica M mount). They are very good, but they've only tasted the Contax G. The others do not know.

    The deformation or curvature lines on a Biogon is almost negligible , I once read that if photographs , a lamppost straight on the edge of an image of the Hasselblad SWC ( Biogon 38 ) and then the large image, the 1x1 meter ... distortion is less than 1 mm at the side . I later found that this is true.

    That makes me wonder if my Horseman 6x12 is really 12cm wide. I'll have to get it from storage to measure it.
    I would not be surprised if it is not. For example, the two kinds of 6x9 Veriwides have different widths.

    jac, for most makers of cameras and roll holders nominal 6x12 is 56 x 112. Linhof is the big exception, they make a roll holder with gate 56 x 120.

    Francisco, the 38/4.5 Biogon -- I use one on a 2x3 Graphic -- covers only 84 mm. Total darkness outside of 86 mm. Lens for 6x6 and no larger format, but of course an 84 mm circle gives interesting cropping opportunities.

    Now, I know that ... and so my Biogon 38 is my SWC. The other Biogon 45, 53 and 75 are in my large format cameras.

    I remember now. It is a 1:2 ratio. Thank you for the nudge.

    The widest modern rectilinear lens is 131 degrees:

    There is also the Goerz Hypergon.
    A good chart here.

    Fall-off to the edges is profound.
