Gregory you asked:

"I am interested in pinhole photography and I would like to use a pinhole on my Mamiya 7, which is the body I carry with me. It would be easy to add pinhole with a makeshift shutter to a body cap, but after taking a shot I won't be able to advance the film (because the body won't allow me to depress the shutter button, because there is not regular lens or shutter connected).

Is there a way to advance the file with only a body cap on the body? Any help would be greatly appreciated.

Thanks,

gregory"


ANSWER:

I dont use the mamiya 7 - But cant u expose via the pinhole. cover film with darkslide.
Then place lens and expose with lens cap on. wind the film on...
