While back I bought a BERTHIOT PARIS PERIGRAPHE No.2 SERIE VIa f/14 90mm lens. Was going to use it on my Whole Plate camera but the optic doesn't quite cover the Whole Plate format - dark corners. Seems would be great for 5x7. The lens is so small that including it in my 4x5 outfit a no-brainer. It would project a beautiful circular image on 11x14 film, but even with my one recessed lens board on my 11x14, lens will not focus anywhere near infinity. Out of curiosity tried to research out this lens......

f/14 Perigraphes came in focal lengths of 45, 60, 75, 90, 120, 135, 150, 200, 250, 300, 350, 400, 450, and 500 mm and covered 115 degrees.

Another catalogue online. This one reads 106 & 112 degrees.
Interpolating the info seems as though a 200mm Perigraphe will cover 11x14 with movements.
Anybody out there use a f/14 P Perigraphe?
