Here at Crave, we've coveredbefore. These shooters basically have the colorful plastic blocks stuck to them, and weren't really fully crafted from Lego blocks. However, Fernando Ramirez Martinez has rigged a fully functional medium-format camera out of Lego pieces, some black cardboard, glue, and duct tape.
Martinez's boxy creation snaps 6x6 square-format images, and has a lens with a 150mm focal length. There is no shutter mechanism for this Lego snapper. Rather, it relies on a pinhole with an aperture of F300. If you're shooting under bright daylight with ISO 400 film, a half-second exposure would suffice, Martinez said.
What's interesting about this camera is its film-advancing contraption, which makes use of gears and clutches to hold the film in place so it won't spin freely within the chamber.
It's no proof that this is a real camera without pictures taken with it, so Martinez has also uploaded several shots to his Flickr account. The photos look soft and have a dreamy, nostalgic feel to it. This really makes me want to dig out my old Lego blocks and do something similar.
