With the announcement of the GR Digital IV, Ricoh updates its premium compact camera model. A successor to the GR Digital III, the GRD IV retains key elements from its predecessor. A fixed 28mm F1.9 lens sits in front of a 10MP 1/1.7" type CCD sensor, capable only of VGA video output. There's also a built-in pop-up flash and hotshoe. However, dig a little deeper and the changes are considerably more extensive.
