Pinhole cameras have essentially infinite depth of field. Made one a few years back in the Cub Scouts and it worked great. Also, don't have to worry about cleaning the lens........!

While the pinhole camera admits only small quantities of light, the small size of the aperture (the pinhole) combined with the relatively large distance to the film (the ratio is called the f-stop, focal length divided by aperture) renders a spectacular degree of focus to the entire depth of field (the range of distance between the closest and most distant photographic subjects in the picture).
Many very famous photographers have experimented with exactly this technique, though maybe with some more advanced technology than a cardboard box and a pinhole. Ansel Adams used a similar setup in his famous photographs of Yosemite and desert scenes. Look them up to see the beautiful detail throughout the images.

For spying. No lens, just a tiny pinhole; almost impossible to see.

Because we don't have one with a bigger hole!
