Mounting a LF lens on a focusing ring

[Dan Fromm]

Mauro, how thick -- front of front panel to film plane -- is the wooden pinhole camera?

This is another pinhole camera to adapt for Schneider 58mm XL and 72mm XL - both f. 5,6

Hullo, Dan..
for some reason I don't see a much more extended reply.. Anyway the distance from front standard to film plane is about 75mm - I say about as the front standard may have different tickness over the surface itself..
We are trying to adapt a very inexpensive pinhole camera before trying to adapt instead one of these:

or any other of the like..

A pinhole's focal length is the flange-to-film distance. So the ebay camera's body is 75 mm +/- a little thick.

If you're going to use a box camera a Schneider -XL lens' coverage and, therefore, expense, will be wasted.

If you want to experience the joy of tinkering, by all means adapt a pinhole camera - why not a cigar box? - to take a lens on focusing helical and have fun. But if your goal is to shoot wide angle lenses on 4x5 getting a 4x5 Crown Graphic and lenses that cover little more than 4x5 is probably the better approach.

This https://web.archive.org/web/20180319...4AAOSw9Cpaq4hK is approximately what you want to make. The box is very thin.

Hullo, Dan..
Beautiful camera - very tempted ! Yes more or less is what I aim to..
Certain China or Hong Kong wood pin hole camera makers sell their 8x10 for around 500 USD - beautifully finished ..
