1. The v.2 was much quieter when focusing than my v.1. Whether that is due to age of my v.1 or sample variation, I can't say, but I can say there was a definite difference.

Interesting.  It could certainly be sample variation.  I know some motors and the servo loops can have a surprising variation in noise depending on what exactly the source of the noise is.  Common with some "noisy" lenses in other systems as well.

As to the optical difference that's likely sample variation.  Testing lenses when you buy them is an annoying thing to have to do!
