This year for Worldwide Pinhole Photography Day I used two cameras.
The first was a digital Pentax body with pinhole in a body cap. I have already posted a gallery with those results.
My second camera used is a rather old Kowa SET slr body. The body's shutter mechanism was deactivated, and I mounted a pinhole plate into a "vintage" Alphax leaf shutter, replacing the camera's original lens body. Distance from hole to film plane is 65mm, and with a hole estimated to be 0.14mm in diameter, it yields an f/stop of 464. The auxilary finder on the accessory shoe is needed for aiming.
I loaded this camera with an old freezer stock roll of asa 800 Fuji, 36 exposure.
That 800 Fuji did show its grain, particularly in low light.
