Wide, but not extreme. Some sort of recessed cap would have to be made to go wider. I myself think that large format is better suited to pinhole photography. Enlarging a 35mm pinhole negative to 8x10 is pushing things a bit. Reducing an 11x14 pinhole negative to 8x10 (or 5x7) is better in my opinion. Have Fun, Colin
