Thanks Godfrey
So far so good, so much lighter than I expected.. or from reading specs.
~480g X113 vs ~680g for my A7s+FE35 feels much lighter than the math would imply!
Got a Toshiba FlashAir card for quick on-the-go review&posting after seeing mixed reviews on EyeFi and noticing Leica supports FlashAir (it's a menu option on X113).. works well enough compared to the built in WiFi on Sony cameras, though I'm using PhotoSync instead of Toshiba's own app.
I did have one disconcerting incident that I hope does not repeat - the camera got stuck in C mode despite the dial being in S. Repeated power cycles and removal of battery did not resolve, had to do a factory settings reset via menu to clear it out. I remember older M8/M9 series having OFF/S/C dial issues... would have hoped German engineering had this problem solved by now....
