Here are the first series of pictures of Fuji X20
. Unfortunately, the markings on the lens is pretty blurry, so I can’t make it out what lens is being used on the X20. Perhaps others can identify this better than I can.
The differences between the X10 
and the X20 looks rather minor. Hopefully, the X20 brings us new features and improvements, starting with a f/1.4 lens!

I don’t recall the X10 having the labeling like that. I wish the X20 didn’t. That’s so gaudy.
