The baltic birch 5 x 7" Pinhole Camera from Lensless is features a 3" lens. A tiny precision pinhole in the front panel is the camera's aperture - the shutter is simply a small hinged metal plate that swings up and down to begin and end the exposure.
This pinhole camera features a focal length equivalent of 75mm, which is a very wide angle lens for this format. A starting-point exposure with ISO 400 film in bright noon-day sun is 2 seconds. Since it is designed to accept a sheet film holder, there is no need to load the camera in the dark.
