Ebay 'X10' Leather Cases - Be aware!!
I've purchased one.
Warning: it isn't for an X10 it is for an X100! So it does fit but it has a couple of problems:-
1: The front cut out catches the focus mode selector (switching it to manual!)
2: The rear cover obscures the OVF and presses on it.
As a protective case, and only around £15 or $20, it's still a good buy, and I'll keep it on that basis. But it isn't for the X10, even if the advertiser says it is...
