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.

Every lens is inspected, rather than random checks. One can turn that around and say they do not have their production methods under control if statistical sampling is not adequate.

They pride themselves on their reject rate. Cheers, Dan
