What's the deal with the Sinar Precision Film Holders 4x5?

[PaulSchneider]

Hi guys,

I just came across this sales post:

What is so special about those film holders that warrants a 10x price differential?

Do I really get sharper pictures with one of those? Or is this a waste of money?

Is there any story behind this piece of gear?

Regards

Paul

It will put copyright info on the neg. But for my money it'd have to be a whole lot cheaper!
