The S10 24-72mm F2.5-4.4 VC is a lens unit that slides into Ricoh's GXR body. The GXR 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) sensor with a fast prime lens to a tiny one with zoom lenses (such as the S10). The Ricoh GXR/P10 24-72mm combines a 10MP 1/1.7-inch CCD sensor with a 24-72mm equivalent lens. Like the other GXR/lens module combinations the package offers tank-like build quality and an abundance of external controls but with its 1/1.7 10 MP sensor the camera is still a digital compact at heart. It produces image quality that is roughly on par with other cameras featuring similar sensor/lens combinations but comes at a significantly higher price point.
