I have the Fujifilm black leather case for my X10.
Once the lens is retracted (to OFF), the case closes over it just fine. Mine always goes Case Closed with the Marumi clear filter installed and the metal lens cap in place. The top un-snaps and you walk around with just the bottom on. Have to remove it to change battery/card, or to put on a tripod. SMELLS like leather. Embossed with the X10 logo. I like it a lot, completes 'the look'. Not cheap, but I got mine un-opened from a C List ad for quite a savings.
