Hi, I upgraded the firmware on my X E1 body yesterday. So far everything is running OK. Focusing seems to be at least as fast as before with the 18-55. Also I discovered that although Fuji didn't mention it, the Raw File display problem, which displayed Raw shots in a cropped 16 x 9 format has now been fixed. I am still looking for other improvements but I wonder, has anybody out there discovered other unreported items.
