Richard Ritter just updated his web site with more information on his lightweight ULF camera. Information includes how to buy one. First to be finished will be 7x17s, with other, interchangeable sizes available soon.
http://www.lg4mat.net/ should get you there. I really like the picture of Richard in the vest and hat.
I have no financial interest in Richard's camera-making venture. I jsut want him to get the ULFs underway so he can turn to making ultra-light 8x10s and 5x7s, which he has hinted he might do...
You go, Richard
