I’ve done lots of DIY projects in the past, making camera parts out of all sorts of stuff. I used to do it a lot during my college days, when I had more time and less money. This guy has the same spirit of using trash and scraps to make something useful – a Pringles can was turned into a lens extension tube!
I’ve been meaning to make a homemade tilt/shift lens for my slr’s, but never got around to trying it. Maybe I’ll get around to the project soon. That link has inspired me…
