future potential. When compromise is not an option, this is the camera system you get.
In order to make the best use of the inherent power of the lens and the
image sensor, the ideal solution is to combine both in a single unit. Con-
sider, for example, the low-pass filter covering the surface of the image
sensor.
The dilemma faced is that while the filter helps prevent color noise and
color moiré, increasing this benefit results in an ever greater sacrifice in
lens resolution. Traditional interchangeable lens systems must use a single
low-pass filter for all lenses so they are unable to avoid situations where
the filter effect is excessive or inadequate. With the GXR, on the other
hand, we can design a low-pass filter optimized for the resolution of the
specific lens. In this way, Ricoh has succeeded in effectively preventing
color noise while minimizing filter influence on lens resolution.
For their exterior covers, both
the body and the camera units
utilize a light and strong mag-
nesium alloy with superior
precision-molding, heat-
dissipation, and magnetic-
shielding characteristics. Dura-
bility and high-class impres-
sion are further enhanced by a
high-class, non-slip "pear-skin"
baked finish with strong corro-
sion and wear resistance.

The exterior itself is a functional aspect of the camera.

In a relationship similar to that of an SLR and its lens mount, the guide rail is a
defining characteristic of the GXR system. To create a highly reliable slide
mechanism, stainless steel with superior strength and corrosion resistance was
adopted for the rails. Surface hardness and wear resistance were further
enhanced with a soft-nitriding process, the end result being a high-precision
slide for attachment and removal. The
combination of the slide, the resin compo-
nents, and the pressure-welded springs
give an appropriate sliding feel and quiet-
ness. The reliability of both the mechani-
cal and electrical connections has been
verified in high-stress attachment/removal
testing of the slide mechanism.
