The baltic birch 5 x 7" Pinhole Camera from Lensless features a 12" lens. Lensless Cameras are constructed of different woods. Each model has a tiny hole (1/64" or smaller) precisely drilled in the front panel. The shutter is simply a small hinged metal plate that the photographer swings up and down to begin and end the exposure. The imitated focal length is determined by the length of the camera. The format is determined by the size of the back of the camera, which accepts the film holder. Since it is designed to accept a sheet film holder, there is no need to load the camera in the dark.

This is a baltic birch, 5x7" Pinhole Camera, with a focal length equivalent of 300mm, which is a telephoto lens for this format. Average exposure in bright, noon-day sun is 4 seconds, using 400 ISO film.

300mm/12" Lens    Telephoto

Simplify photography to its basics: Composition and Exposure.

Depth of field is of no concern; everything in front of the camera is equally in focus.

Uses cut film and Polaroid holders. No need to load the camera in the dark.

Related Questions and Answers

Q: 1. This should work with paper?

A: The Lensless 4 x 5" Pinhole Camera can be used with photographic darkroom paper.

Q: 2. does this have any kind of hole so you can attach it to a tripod?

A: Yes, the Santa Barbara 4x5 pinhole camera has 2 threaded 1/4"-20 mounting points for either portrait or landscape shots.

Q: 3. I purchased this camera but misplaced the exposure guide. Can somebody please provide this information? I purchased the super wide angle version, if that makes a difference. Thank you!

A: This is a Baltic Birch, 4 x 5" Pinhole Camera, with a focal length equivalent of 50mm, which is a super wide angle lens for this format. Average exposure in bright, noon-day sun is 4 seconds, using 400 ISO film.

Q: 4. Will this hold most common film holders? I see someone posted a link to a 2 pack for $100. I would like to try and limit the price if possible. Thank you.

A: Yes, any of the standard 4x5 cut film holders will work quite nicely. I have 15 or 20 of them that I load at one time, so there is no need to do so in the field.

Q: 5. does it accept paper or just film?

A: You need to use a film holder on this camera, since the actual back is not light tight. It's only light tight once there is a film holder in place. Assuming you can load a 4x5 film back with a sheet of paper, then you can shoot either film of paper with this camera. Hope this helps.

Q: 6. What is the closest focus distance for macro photography?

A: The focus distance is not specified but it has an f/420 aperture. With such as small aperture, nearly every non moving subject will be in focus.

Q: 7. I am looking into the Lensless 4x5 pinole to photograph Civil War reenactors. Currently shoot digital & post process to make them look authentic-ish. I know I will need film holders to preload before going out. My questions is with using the "direct positive paper" instead of film. Does it need any type of processing or is it ready to go like "instant film camers"? Trying to find a way to deliver images on site. Thanks.

A: Direct positive paper still needs chemical processing in a darkroom with traditional type paper developers.

If you are using 400 speed film choose ISO 400 on the meter or camera. Then cross reference the reading vs the chart for f/230.I have another chart that shows me the additional time required because of the film's reciprocity failure rate. (This will be specific to the film you are using.)
