What is this???
I believe the widest would lens be a Hyperon f22-31 with 110-135 degrees coverage.
a 3" hyperon 135 degrees with star filter to balance out exposure
The version which loses 25 degrees but does away with star filter. I guess it's not needed with the modest 110 degrees.
I believe this is a 4 1/2 " with of 110 degrees
BTW good luck as you will need a big pile of cash in most cases. Bummer:(
Louis beat me to it - the answer is indeed 75mm Hypergon with fan:

Save those pennies...
I have a Sinar Norma 121mm F8 Schneider Super Angulon, and when forward focused a bit, will just illuminate an 8x10 plate without cutoff. At infinity focus, it dosen't make it.
The super angulon 90xl stopped all the way down just scratches the edges of 810 with no movements. In the right situation it can be very dramatic.

That's a Zeiss Doppel-Amatar. The construction is sometimes called "reverse Dagor", meaning each cell has a positive lens between two negative lenses - rather like the Schneider Angulon.Quote:

For many years I used a Nikkor 120 SW f8. It's been wonderful, my workhorse for architectural work. It covers 810 thourh in practice there are no movements available. That hasn't stopped me making wonderful, profitable photos with it. You cut your coat according to your cloth and this cloth has served me well.
Good luck

Mine is still in the original barrel with wheel stops, but at least one person has had one mounted in a shutter, so it is possible.
