Here are pics of my "zhnnged" x10:
Kaza Camera Case in Royal Blue - The x10 fits into the external case, lens hood and all. Kaza also offers brown and black versions of the case but I think the blue is more unique. Case workmanship is better than the original Fuji leather case and more importantly, it has an opening at the bottom for access to the battery/SD card and speaker. Also comes with a matching blue neck strap (not shown).
Gold Convex Soft Release from ebay - Some swear that soft releases allow you more steady shots but for me, it's more aesthetics than anything else. How many cameras allow you to add colour to the shutter button with a soft release, right ? Try screwing a soft release onto the Olympus XZ-1, Canon S100 or even the Sony NEX-7 ! :sticktong
52mm Lens Adaptor and Metal Hood from ebay (3rd party) - Costs much less than the original Fuji lens adaptor and hood but still fits very well ! Not sure whether it's intentional but the printed code on the hood (LH-X10) actually aligns to the top when I screw the hood all the way in (first pic) - nice ! I'm not sure how effective a lens hood is but hey, it certainly adds to the retro look of the x10 ! More importantly, the Kaza case swallows the camera and lens hood whole ...
Hoya PRO1 Digital UV Filter (52mm) from ebay - You can't really see it in the pics but it's there to protect the lens from finger prints and knocks.
Leather wrist strap from ebay - Used interchangeably with a Gordy sling strap that I got (not shown).
Black hotshoe cover from ebay - Inexpensive, and it completes the look !
