Another vote here for just do it. The F6 is a special camera, and the specs alone don't tell the entire story IMO. There's something special about the tactile feel and operation of the F6 that is noticeably superior to other similar cameras I've tried. Nikon put a LOT of work into getting the shape and materials just right, and that makes the camera a real pleasure to shoot.
I remember that article - it was a really interesting write up on the development of the F6. Just tried to find it now but couldn't locate the English version. Here's the
Japanese version if anyone wants to put it through Google translate.
