Ricoh has released firmware v2.30 for its GR Digital IV enthusiast compact. The latest update is the fifth for the GRD IV, and adds a couple of features, slightly modifies the camera's behavior and fixes some minor bugs. The latest update brings the white balance options of the GRD IV into line with the more recent, large sensor, GR model, for which Ricoh has also said it will provide function-enhancing firmware.
