GR DIGITAL IV

The camera is outfitted with the high resolution, high contrast, low distortion GR Lens 28 mm/F1.9. The lens has a large aperture, and corrects aberrations of all types without compromise using Ricoh-developed optics design. Thanks to a 6-group, 8-element lens composition and three special low-dispersion lens elements, high resolution and high contrast are realized while chromatic aberration is suppressed. Furthermore, with the two high-precision, aspherical lens elements, there is hardly any distortion that is noticeable.
The optimized coating tamps down on ghosts from backlights and point light sources. The beauties of the Bokeh and of the beams of light that the 7-blade diaphragm produces are also exceptional.

* The focal length is the corresponding value for a 35-mm camera.

With the newly-developed image processing engine, the GR ENGINE IV, color noise reductions when taking high-sensitivity photographs have been achieved. The Auto and Multi-P AUTO algorithms for white balance have also been improved, so that the effects of lighting conditions and subject color are controlled, helping to stabilize and reproduce more favorable colors. Since we also tuned up the color balance, even rather casual subjects like white clouds in a blue sky are rendered more impressively, with rich colors.
Furthermore, the image processing algorithm has been optimized and improvements have been made in the optical filter. The quality of resolution has been improved so it vividly renders subjects in great detail.
