Overview
Ricoh GR Digital III
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.
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.
Freedom from ghosts.
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.
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 colour saturation. Colour reproduction and tonal
gradation performance has also been significantly improved.
