Hello friends, I have in my mind a weekend project of building a simple plywood box-y camera to be used with some 8x10 (well, in fact they are 18x24cm) fidelity holders and I need some opinions/advice. One possibility is to make it a pinhole box - which would be the simplest thing and I could just "scale up" a 5x7 pinhole camera I've built before. But what IF I wanted a lens. I've got a 120mm lens that might just cover the desired format, although I use this lens on my other cameras frequently. Or I have a 240mm G claron in a strange big (thick) barrel that I am not using at all - would that be a better fit? Would it be possible to make a point-and-shoot box with this lens? What would be your choice? Any advice/opinion would be welcome. Thank you.
