My first pinhole is the Vivitar focus free camera. I bought it off of ebay. Someone took out the lens and replace with a pinhole. To use you position on tripod, place your finger over lens hole, slide the lens cover open and carefully remove your finger without giggling the camera or tripod. To close you cover with your finger, push the shutter button this allows you to advance the film and close the shutter cover. The hardest part is not giggling the camera when removing your finger. I paid $17.50. All in all not a bad camera for the price.
My 2nd pinhole camera is the Laser Lenox body cap with a pinhole in it. http://www.lenoxlaser.com/index.php?dispatch=categories.view&category_id=3 I paid $33.00 for Laser Lenox pinhole body cap. I bought the Olympus camera in the 1980’s. . I have only taken one roll, so the jury is still out on it. There appeared to be some light leaks on the first roll, so I may put tape around the edges of the cap before I take the next roll. It also was not as sharp as I had hoped. I plan to buy a cable release to see if that helps. Unfortunately you cannot lock up the mirror on this Olympus model and that could be causing some blurriness. 2-27-2011
