Many of us here at WECC are humble owners of the wondrous little digital rangefinder from Fujifilm called the X100 / X100s and to go along with the compactness of the camera and others like it, you'll need a small but capable bag for it.
The Pleasure Dome is close to perfect for this purpose. It features a moderately sized main compartment with a removable velcro divider allowing different configurations based on the extras you carry with you, It would easily fit most point & shoots along with many 4/3 camera set ups. It's also very light and won't cause any undue strain on your back or shoulders. There are 2 size options from Crumpler, Small & Medium, depending on your needs both are a interesting option.
On the interior of the front cover is a pouch with enough space to carry a few spare batteries and your keys. The interior is lined with soft felt-like material which protects your camera from scratches.
Without any extra camera accessories such as the attachable WCL-X100, TCL-X100 focal length adapters or lens hood from Fujifilm, the camera sits in the 'small' bag horizontally facing forward quite comfortably yet won't move around. With the lens hood the 'medium' would need to be your choice as the hood finds the bag a bit to snug for my liking.
With the 'medium' bag another configuration would be to store the camera on its end and using the divider, allow for a space to store at least one extra rangefinder lens or lens adapter for the X100s. This would be a great street and portrait combination, especially when travelling where you don't want to carry too much with you.
In my use of the bag (small) when wandering around doing street photography, the only real issue I found was the ability to stow and remove the camera quickly (I use a lens hood) . This is where a holster bag with a vertically opening cover may be more suitable. I carry my X100s either in my bag or in my hand with a Gordy's wrist strap I have on the shutter-button side so this 'quick removal' important to the way I personally shoot. *edit the medium pleausre dome solves this problem
If you don't shoot that way, the 'small' Pleasure Dome has everything you need in a compact, comfortable and protective form factor that will hold the compact rangefinders we've grown to love shooting with. No more carrying around that huge, heavy and scoliosis inducing DSLR!
Both the 'Small' & 'Medium' options area vailable, however it is more important for you to work out which way you lioke to roll when making a choice. The 'small' is somewhat a smaller form factore and does an equally admirable job with a little less bulk. Once again if your styling the hood and or wish to pop a few extras in the bag the Large is the bag of choice.
Both sizes are a great bag with some fantastic features, I really feel it is worth a look when deciding on a home for your Fuji X100/100s or any other small form factor camera.
