Anybody here ever did pinhole photography use a modern AF camera?
I started about a year ago making some pinhole lense for a canon 620 and ElanII. I whent to a local photo shop and bought a few spare body caps and use a heated small needle and poke a hole in the center of the cap for the aperture. I whent from the outside > inside on one and the inside >outside on the other. The later , had a smoother edge around the aperture.
Then I whent out to a fishing pier and setup my camera on tripod and started making exposure using a timer of the sun over the bait house. It took me about a full 36exp roll of film in order to get 2-3 nice photos. I later determine my apertue was F128 or something around that. You get a light meter and timer you can calculate your exposure pretty good, just factor in for reciporatory failures if you start making 1-3sec or longer exposures. You can also place a std 50mm lense on the body, take a reading using the onboard metering and then adjust the exposure based on your guessed pinhole aperture sized, and bracket 1-2 stop above and below.
btw: if you do try this using a canon body, you have to to place the camera on manual and used the buld setting since the camera will not have a lense to control for apertue cuz the electronic contacts aren't closed electronically.
if you want the expensive pre-made lense, take a look at the site online or ebay or just make one using the hints from
