Great Case for the Ricoh GR
I just bought a GR, so I immediately went out to find a case.
At Curry's I found the Samsung Galaxy Camera Pouch which is almost perfect. And it is only £10!
The GR fits snugly in the pouch, although it is not a tight fit - you can push you finger down the side when the camera is inserted, or through into the space at the top when the pouch is snapped shut.
This means that there is probably room for the camera if it is 'wearing' the half-case. It is also possible to push a spare battery right down to the bottom of the case and then insert the camera.
The extra size definitely means that you can't put the pouch in to your shirt pocket, but it will fit in a trouser pocket.
You will be able to see images on the web, including a brown version at Samsung's website if you search for "Samsung Galaxy Camera Pouch".
The part number of mine is: EFC-GC1SBEGSTD.
