future potential. When compromise is not an option, this is the camera system you get.

Slide mechanism for high precision and reliability

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.

Designs optimized to make the most of lens and image sensor

capabilities

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.

The exterior itself is a functional aspect of the camera.

Magnesium alloy cover

For their exterior covers, both

the body and the camera units

utilize a light and strong mag-

nesium alloy with superior

precision-molding, hea t-

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.
