I’m building an ultra large format camera to take sheets of photo sensitive paper up to 3 meteres wide, although will start shooting with paper 2.4m x 1.2m.
If there any exisiting lenses that can be found for this purpose? Of course pinhole will do, but at this size optimal pinhole will be about f/1200, hoping to find something faster if possible.
I’m hoping to have infinity focus when lens is 2-4meteres from paper, although can adjust this if necessary
Hoping for anywhere between 40-74 degree angle of view horizotonally, preferring 74 degrees.
