Product Description
The subject may not realize the photo has already been taken. With the GR DIGITAL, that is the kind of quick shooting you will find paired with superb image quality. The new 28mm/F1.9 lens features outstanding brightness. A convergence of sophisticated image processing capabilities and comprehensive shooting functions: GR DIGITAL III. Sparking an explosion of photographer creativity, a new legend is born.
Ricoh GR III Digital Highlights
The photographer's ideal lens: 28 mm/F1.9 GR Lens
As photography lovers themselves, the developers focused all their passion and creative vision on the creation of a new lens of unprecedented power: the 28 mm/F1.9 GR Lens. If image quality is the priority, set a lower-than-ever ISO sensitivity. If capturing a shutter chance is the priority, set a higher-than-ever shutter speed. F1.9 expands the freedom and scope of your photographic expression.
Pride of the GR series: Superb optical performance
So how was this lens able to control the various types of aberrations that increase as the aperture increases? While maintaining a basic configuration optimized for thin storage, frame aberration was reduced by adding two elements in one group to the rear. In addition, three special low-dispersion lenses were used to achieve high resolution and contrast while minimizing color aberration. The use of two high-precision aspherical lenses made distortion almost unnoticeable. In order to create this ultra-high-precision and high-performance lens, highly precise manufacturing processes and an exclusive control system were newly developed. It was dedication and tenacity that gave birth to this jewel of a lens.

Superior backlight performance
Ghosting is one of the causes of image quality deterioration. To eliminate the problem, all of the individual lenses that are part of the GR lens have been covered with the multi-coating optimum for each. To minimize the small residual reflection striking the CCD, we also ran original simulations repeatedly to determine optimum conditions for lens curvature, etc. As a result, we successfully suppressed ghosting, particularly that caused by off-screen light sources such as the sun.
GR ENGINE III for low-noise, high-resolution images
Newly developed image processing engine GR ENGINE III enables precise noise reduction by processing the signal close to its CCD-output state. Various types of noise are effectively reduced while maintaining resolution and color saturation. Color reproduction and tonal gradation performance has also been significantly improved.
10-megapixel high-sensitivity CCD and AFE
With the new CCD, rather than increasing the number of pixels, we have about doubled sensitivity compared to the previous model (GR DIGITAL II). Even at ISO 200, imaging performance is at or above the old ISO 100 level. This higher ISO sensitivity makes a clear difference in image quality.
Suppressing whiteout to create "high-reality" images: Pixel output interpolation algorithm
Control whiteout with the pixel output interpolation algorithm, Ricoh's original image processing technique. Comparing the output of each pixel, the algorithm interpolates image data in whiteout areas. This expands dynamic range by up to +1 EV equivalent. Using this extensive data to generate the JPEG, even for 8-bit (256-tone) images, it is possible [6653] xxx The new GR DIGITAL III takes the GR line's traditional high image quality to an even higher level with a new image processing engine, a new CCD, and the newly developed 28 mm/F1.9 GR Lens. Performance has also been enhanced in areas such as quick shooting, operability, and power of expression. The GR DIGITAL III 1. Newly developed large-aperture lens. The adoption of the new F1.9, f-6.0 mm (equivalent to 28 mm for 35 mm film cameras) lens for the GR DIGITAL III takes compact-body cameras into a new realm of images. This lens makes it possible to shoot with a faster shutter speed than could be used on previous models, or to shoot with the same shutter speed but at a lower setting for ISO sensitivity. Despite the large F1.9 aperture, the new lens achieves a resolution level equivalent to that of the F2.4 GR Lens. The use of a newly developed lens drive system has made it possible to achieve greater image quality in macro photography. 2. Taking the GR DIGITAL concepts another step forward, the GR DIGITAL III achieves even greater image quality. The new image processing engine GR Engine III is installed. Using newly developed noise reduction technology, it enables highly sophisticated noise processing to be done while maintaining superior resolution, tone characteristics, and saturation. The new high-sensitivity CCD (1/1.7 inch, approx. 10 megapixels) achieves high-sensitivity properties through the use of a new process. The com Shipping Weight: 2 pounds
