A test shot using my 35mm "N" back on my ETRS. The back came packaged with a camera and a few lenses, I would of never purchased the back by itself. I have too many great 35mm SLR's to shoot film in. The "W" back might of been more interesting because of it's 24x54mm image size, but then again you can always crop a 645 or 6x6 frame and get the same image.
