I shoot a lot of infrared film and i also shoot a lot of 11x14. Anout a year and a half ago, I bought a healthy supply of Efke EIR in 11x14 and have had a learning experience. My camera is a Chamonix and the standard bellows are not IR safe, so the first challenge was to solve the bellows fogging (a subject which has been discussed here regarding Chamonix). The answer was to buy their leather bag bellows and it works very well. Unfortunately, the problems with IR and focusing visible and IR light compound with longer focal lengths and a big film. none of my 11x14 lenses could perform, yielding bizarre triple images. I bought a few more lenses to no avail but finally had good success with an APO Nikkor 360mm and a front mounted Packard shutter. The setup is excellent..
