Behold the Legotron Mark I - A Large Format Camera Made from Legos
I get paranoid enough about dropping my $150 point-and-shoot, so I could never imagine lugging this thing around, but it&amp;#8217;s pretty awesome and definitely gives new meaning to the phrase &amp;#8216;toy camera.&amp;#8217;
This was made by  Cary Norton who lays out the specs:

I have no clue how many pieces are in this camera
It&rsquo;s dimensions are roughly 7&Prime;x6.5&Prime;x7&Prime;
The main parts are a Main box, internal box, film holder/ground glass slot, lens board, lens.
The lens is a 127mm &fnof;4.7 I got on ebay for ~40 dollars
The  lensboard is two Plates deep and fits perfectly in the slot I built for  it (though, I cut it down to one plate in the center to actually mount  the lens).
Focus is achieved by sliding the internal box forward and backward.
The  focus range is limited to roughly 3 feet to about 18 inches. It&rsquo;s good  for portrait, but certainly can&rsquo;t focus to infinity. Mark II (once I get  to that) should have a way better focusing range. I&rsquo;m planning on  making a pinhole lens board too.
The ground glass is just plexi,  sanded with various fine grits. It&rsquo;s held in place by a film holder that  previously had light leaks, but now has the aluminum center cut out.  The fit is tight and I ran a line of liquid nails too, just in case.
