Thank you for your response
But I did not want a wide angle image, so for instance, if I want to
make images of fruits, with a 6X9 120mm film, is my image going to be
distorces ? How can I have a normal image for a 120mm film ? I do have a
zero 6x9 camera and thinking to built a 4X5 one
Thank you so much
