Re: [pinhole-discussion] 35mm Short focal length
I use an Exa with a pinhole placed in an extention tube adapter. About 25mm focal length. http://www.slonet.org/~rheather/EXA2.jpg Argus cameras with body shutters like the C3 C44 and C21 markfinder can be used An old folder like a balda could have the bellows and front removed and a very wide angle pinhole placed. Larger format is easier to deal with for many situations. Richard Heather Stephen Rees wrote: > I have a friend who has been experimenting using 126 cartridges.

My shutter is a piece of dark foam (looks like a cube) cut to fit snugly into the front of the camera, I carved a cavity at the rear of the foam so it does not get in contact with the pinhole. I originally used this camera with a 0.03mm diameter laser drilled pinhole a pinhole manufacturer sent me for free, but diffraction was too much to get images, besides, 0.03mm is optimum for just a 0.66mm focal length camera!!. I substituted that pinhole with one made by myself with a diameter of 0.005", that is why you see 2 different f/stops written on the foam. Current f/stop is f/90. Here is the shutter: http://members.home.com/penate/cameras/sf.jpg http://members.home.com/penate/cameras/sr.jpg Guillermo

Can anyone recommend an inexpensive 35mm camera that can be converted into a pinhole camera with a focal length less than 30mm ? You may want to tell your friend to stock up if he has a source for the 126 cartridges - Kodak stopped making this at the end of 1999. (http://www.p at ???/diary/1999/1999_July.php) The 126 cartridge fits perfectly onto a toilet paper tube, and also some paper towel tubes. There is a ridge around the film opening that is the same size as the tube. You only have to bend the tube into a square shape to get it around the opening. I put a pinhole on the end of the tube and had a nice "telephoto" 126 camera. You can also cut down the tubes to different focal lengths. I just added a photo (126bodies.jpg) of my collection of 126 "bodies" to the upload gallery: http://www.???/discussion/upload/gallery2001.php I never got a decent image with the paper towel tube, but the toilet paper tube did fine.

I have 2 examples for you, both are 35mm format pinhole cameras, images shown have been scanned with my cheap flat bed scanner: The first one is my 14mm focal length camera, made out of a Kodak disposable camera, I carved material around the lens to avoid vignetting, recessed the pinhole to be 14mm from the film plane, for which I used a piece of black plastic and glue, the pinhole was then mounted at the back of this black plastic. Here is a frontal view: http://members.home.com/penate/cameras/14f.jpg Here is a rear view w/o its back cover: http://members.home.com/penate/cameras/14r.jpg Here is a bottom view showing the nut I glued to be able to use the camera on a tripod: http://members.home.com/penate/cameras/14b.jpg Second one is a 12mm focal length camera, made out of a cheap Japanese range finder I bought for $3 at a photo fair (had no lens, but good film winding mechanism). I also recessed the pinhole lens to be just 12mm from the film, glue and a piece of brass stock is all I needed. Here is a frontal view: http://members.home.com/penate/cameras/12.jpg Basically any camera can be converted to whatever focal length you want/need. I also have a 6x6 with a focal length of 35mm, done in a similar fashion as the 12mm above. Hope this images gives you some ideas. Guillermo

http://www.a1.nl/phomepag/markerink/mounts.htm This is the address for an extensive list of film to flange distances which shoukd point you in the right direction. Leica LTM cameras and their copies make the widest body-cap focal lengths. I convert 17mm Konica Single-Use Panoramics to wide-angle pinhole cameras. Wide enough for most purposes. Many cheap plastic cameras have a focal length of less than 30mm. Old folding 120 cameras also make great wide-angle pinhole cameras with that big negative. . .

Re: [pinhole-discussion] 35mm Short focal length
Get a Holga ($15), cut the lens and shutter off and glue your pinhole directly to the body or inset it. I think the focal length of my Leica pinhole body cap is around 30mm. It's nicely wide angle. The Hasselblad one is about the same focal length as the lens and not very wide angle at all. - Original Message - From: Stephen Rees To: Sent: Saturday, July 14, 2001 3:38 AM Subject: [pinhole-discussion] 35mm Short focal length > I have a friend who has been experimenting using 126 cartridges.
