A review of the Ricoh GR Digital has been published at ephotozine.

The results of the review:
“Personally, I love the no-frills approach Ricoh have taken with the GR Digital. For me stripping down the camera to its basics and concentrating on quality has paid dividends and created a camera that is fun to use, as well as providing excellent clarity. […]
I am impressed by the noise performance at lower ISO settings, and the higher sensitivities are acceptable if you are willing to accept the limitations. […]

In summary the positive points of the Ricoh GR Digital are:
Clarity of images.
Build quality.
No-nonsense design.
Optional wide angle converter.
Macro mode.

The negative points:
Display blackout when using continuous shooting.
Time taken to write RAW images.
Auto white-balance tends to create a strong cyan cast.”
