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.
The slide mechanism adopted for attaching and removing camera units enables changes to be made quickly and securely.
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.
The GXR remembers shooting settings in both the body and the camera unit. It is possible to select in advance which settings are to be used when the camera unit is changed. Select the body settings if you want to shoot and process images in the same way regardless of the camera unit. Select the camera unit settings if you want to change settings for image creation in a style specific to the camera unit.
The DIRECT button is located on the back of the GXR. When in shooting mode, pressing the DIRECT button displays the current shooting settings. Since the settings are transparently displayed over the image, the DIRECT screen is convenient for simultaneously checking both the image and the settings.
A wide range of settings can be registered in advance and instantaneously accessed by just turning the mode dial. The GXR provides three My Settings to enhance the photographer's ability to respond instantly to scenes and creative inspirations.
