Holga Pinhole Lens. Principle of pinhole lens: Light from a scene passes through this single point (pinhole) and projects an inverted image, on the camera sensor. The human eye in bright light acts similarly, as do cameras using small apertures. Within limits, a smaller pinhole (with a thinner surface that the hole goes through) will result in sharper image resolution because the projected circle of confusion at the image plane is practically the same size as the pinhole. There is no aperture and focusing rings on the lens implies aperture and focusing are not to be controlled. When this lens is being used, you need to "tell" the camera to shoot without lens and using a tripod is recommended.
