Ed, what set me off was a suggestion to the effect that the OP would need 24" of bellows to shoot at 1:1 with a 300 mm lens. This is absolutely true, but seems a little odd in context because the OP seems to want a CC-401. Very capable camera and all that, but its catalogued maximum extension is 21".

Funny thing is, in post #1 in this thread the OP said that his goal was to shoot portraits with flash in a studio. I worked for most of my life as a statistical/management consultant and one of the first things I learned was to pay attention to -- extract it by torture, ideally without refinements of cruelty, if necessary -- what the client wanted to accomplish.
IMO the best advice in this discussion came from Jim Jones, who suggested that the OP read a few books before doing anything else. I've suggested the same books to beginners, am a little ashamed that I didn't beat Jim to it.
