....i'm convinced now....this is an antidote to the little camera people - looking forward to seeing your b double(veryLargeTruck)setup now bc

Well, I got it wrong there yesterday, soLong. A pinhole camera does not have any optics, and it does not focus because of that, making that you can project an image at any distance from the hole. 

With a lens like this, light does get focussed, and you can't just use any distance to the lens as projection plane. 

 

That does not make a truck for "portable" big pinhole camera less cool, just not with this lens!
