Ricoh GXR interchangeable unit camera, previewed

After several weeks of rumors Ricoh has unveiled its first digital system camera, the GRX. The system takes a novel approach by offering interchangeable slide mount 'lens units' - sealed modules containing both optics and sensor, meaning it can switch from a large (APS-C) 12 MP CMOS with a fast prime lens to a tiny 10 MP CCD (with a 24-70mm lens). We've had a pre-production GXR system in the office for a week and have produced an in-depth hands-on preview which you'll find after the link. We've also taken lots of pictures with both lens modules so look out a little later today for an extensive gallery of samples.
