Ricoh GR II compact digital camera. The GR II is equipped with the wide-angle 28mm F2.8, which achieves both a compact size and high performance. Using uncompromising design with a superior fixed focal length of 28mm, sharp, skillful depictive performance is available from the maximum aperture f2.8. In addition to a unique, newly developed lens construction, glass with high refractive index and low dispersion qualities were used, along with optimized placement of aspherical high-precision molded glass lenses for aberration removal to the utmost limits, even image quality and contrast from the center to the edges of the image, and high resolution. Coupled with a lens construction that reduces ghosting, and multi-coating on all surfaces, this lens possesses excellent resistance against backlighting. Of course distortion and chromatic aberration are reduced to an absolute minimum, for the best overall optical performance of any GR model. With sufficient aperture efficiency and a 9-bladed iris aperture, beautiful blurring effects to the edges of the image with minimal falloff are achieved. Also equipped with an ND filter that can be manually controlled for a wide range of photographic expression. The GR comes equipped with a high-sensitivity, wide dynamic range APS-C large-size CMOS sensor (Approx. 16.2 megapixels (camera effective pixels). Improved shadow noise characteristics makes a routine high-sensitivity shooting at ISO 3200 possible (Max: ISO 25600). By making the camera low-pass filter-less, the excellent lens characteristics are used as-is, providing clear depiction all the way to the edges of the image. By designing the sensor and lens to be mutually optimized, and inclusion of a large-format sensor, the GR achieves a compact, slim body, appropriate to its namesake.
