[Bill ONeil] "I had just heard from a guy that the new adaptor moves the lens further from the sensor, thus making it more true to the original focal length."

That can't be right. If the distance between the lens and the sensor isn't exactly right, the barrel markings will be off and you'll lose the ability to focus at infinity.
