A made an other camera easier to load and now it image seems almost perfect.
I just have to make holdes for the sides bothers because the paper is following off.
It has a little bit vignetting but after cropping the edges it will be not very evident.
It has a 0.410mm pihhole
Focal Length: 140mm
I load a 9,5x7in paper in the camera but after crop I guess it will be 6x8in. Not bad.
