High speed Pinhole Using a Meniscus Lens in a Body Cap Sony Alpha Konica Minolta Maxxum 7, 5

The Holga "cult " camera uses a 60mm FL positive meniscus and is a medium format camera.
High quality meniscus lenses are available inexpensively either by removing from discarded cameras
or by buying through a lens wholesaler such as The Surplus Shed.
A fixed focus arrangement similar to the Holga can be created by simply modifying a DSLR body cap and
inserting a positive meniscus of the correct focal length. Waterhouse stops can be used to provide hyperfocal focusing.
