Ricoh GXR SLR Camera Body 10 MP CMOS 4288 x 2848 pixels Black

New System
Capture the true face of your everyday world. It is the unaffected expression that is the sweetest. For this kind of candid photo, the most suitable camera must be small enough to be always with you and always ready for a casual shot. On top of that, the ability to change lenses (and therefore perspective on sensibility) to match each change in scene and mood will spur you to new levels of shooting motivation and creativity. The ideal tool for this purpose is an unprecedented new camera system. GXR. The compact and versatile interchangeable unit camera system.

An innovative camera system expanding your range of expression with interchangeable units
GXR is a new camera system that consists of a body and camera units. Each camera unit contains a lens (focal lengths differ between units), an image sensor of optimum type and size for the unit, and an image processing engine. By changing units, the photographer can handle a diverse range of scenes in a way that satisfies sophisticated requirements for photo expression. The slide mechanism adopted for attaching and removing camera units enables changes to be made quickly and securely.

Compact, high-performance lens design enabled by the interchangeable unit system
It is the lens that gives life to the photograph. In interchangeable lens camera systems up to now, the distance from the mount and the back of the lens to the sensor image plane was subject to requirements for flange back distance and back focal length. This made it difficult to achieve both compactness and high optical performance. Eliminating the lens mount, however, means that the back focal length can be freely defined for the GXR, enabling the new system to use the most optically efficient lens designs and giving it excellent potential for future expansion. This practical concept has given birth to camera units that achieve compact size without compromising image quality.

Optimum tuning to realize all the capabilities of the lens and the image sensor
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. Consider, 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 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 filter optimized for the resolution of the specific lens. In this way, Ricoh has succeeded in effectively preventing color noise while suppressing filter influence on lens resolution.

No worrying about dust when changing lenses. Highly airtight system for superior dust proofing
The ease with which dust can adhere to image sensors has been a system problem for interchangeable lens digital cameras up to now. In the case of GXR camera units, however, the lens and the image sensor are integrated into a single unit. This structure makes it difficult for dust to get in since it is not necessary to expose the inside of the camera when changing lenses. In addition, the inside of the units are highly airtight with light-shielded walls. Even in highly dusty shooting environments, camera units can be changed without hesitation.
*In order to protect connectors from dust, please use connector caps on both the body and the camera units when not attached.

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. In order 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 that enables secure attachment and removal. The combination of the slide, the resin components, and the pressure-welded springs give an appropriate sliding feel and quietness. In the development, high-stress attachment/removal testing was done to verify the reliability of both mechanical and electrical connections.

Durability and high-class feel worthy of regular use. Magnesium alloy exterior
Both the body and the camera units utilize a magnesium alloy exterior. Light, strong, and exhibiting superior precision-molding, heat-dissipation, and magnetic-shielding characteristics, magnesium alloy is an ideal material for digital cameras. With a non-slip "pear-skin" baked finish for both corrosion resistance and a high-class feel, the GXR exterior achieves durability, reliability, and high-class impression.
