For people looking for these (and other) articles, the Society for Amateur Scientists URL:http://www.sas.org/ sells a CD-ROM with the complete set of "Amateur Scientist" articles from _Scientific American_. -- Brian Reynolds | "It's just like flying a spaceship. | You push some buttons and see http://www.panix.com/~reynolds/ | what happens." -- Zapp Brannigan NAR# 54438 | |

I love it when engineers poke at each other. Makes for great
entertainment. Of course Nicholas is right. I can't imagine Fuji hand inspecting each and every lens that they make. Still, the make some of the finest LF lenses in the world. :-) Nicholas O.
