Pinhole Lens
Pinhole photography is one of the oldest and simplest ways to capture an image. By letting light pass through a tiny hole, an inverted image is projected through it, no glass lenses needed. Pinhole photos are known to have a softer look, near infinite depth of field (everything appears to be in focus) and usually long exposure times.
This pinhole lens (or objective, since it has no glass elements) is designed for Nikon F-mount SLRs and DSLRs. It has an effective focal length of 40mm, which is the widest the lens could possibly be, limited by the clearance required for the camera’s mirror. A laser drilled 0.2mm pinhole gives it a fixed aperture of f/200.
