Besides m4/3, what other system do you own?

Centered around an X100 and an XPro 1.  I only have the 35mm for the X Pro right now, I will likely add a couple lenses in the next year.

I also have some Minolta and Nikon lenses hanging around - the Nikon 500/4 MF I can use with no loss of functionality with an adapter.  The Minolta stuff (like the 80-200/2.8 G) is dinged up enough that there isn't enough of a reason to sell it.
