Ricoh GR LENS A12 28 mm F2.5, the fourth camera unit in the GXR interchangeable unit system. Introduced in December 2009, the GXR is a revolutionary new interchangeable unit camera system in which lenses can be changed by mounting camera units that integrate lens, image sensor, and image processing engine into a single unit. In addition, to fully utilize this system\'s unique ability to accommodate interchangeable units other than camera units, Ricoh is also investigating possibilities for development of a variety of other devices. The new GR LENS A12 28 mm F2.5 brings together a newly developed 28 mm wide-angle fixed focal length GR Lens, an APS-C size CMOS sensor, and the proven GR Engine III image processing engine to create a unit with high flexibility, high image quality, high-speed shooting ability, and high power of expression. Newly developed GR Lens and APS-C size CMOS sensor for strong resolution and imaging power The new 28 mm equivalent GR Lens has a 6-group, 9-element configuration. Incorporating two aspherical lenses, one special low-dispersion lens, and multiple high-refraction-ratio lenses, this extravagant lens configuration achieves strong resolution and imaging power to the edge of the frame. The lens thoroughly corrects for various types of aberrations while at the same time utilizing a floating lens structure to suppress performance changes caused by focusing. The result at all shooting distances
