Ricoh GXR
Ricoh GXR is an interchangeable unit camera system in which lenses are changed by using a slide-in mount system to attach camera units to the body. The camera also features Built-in flash and accessory shoe, DMI connecto and a 3.0-inch 920,000 pixels transparent LCD.  The camera measures 114 x 70 x 29mm (4.5 x 2.7 x 1.1 in) and weighs 160g (5.6 oz).

The GXR launches with two very different optional lens modules. Although the body is very thin, how pocketable the camera is depends entirely on the lens module mounted: the S10 zoom unit maintains the low profile when not in use (it collapses when powered down) but the A12 prime is a fairly large unit.

Ricoh GXR: Key features

  • Unique flat sliding lens mount
  • Interchangeable sealed lens/sensor units
  • Compact Magnesium Alloy die-cast body with 'GR coating'
  • Extensive customization options and external controls
  • 3.0" 920,000 pixel LCD
  • Built-in flash and accessory shoe
  • Optional electronic viewfinder
  • HDMI connector
Each lens unit contains instructions and parameters specific to its own sensor and optics, meaning that different lens units will change slightly the features, behavior and performance of the camera body when attached. Some of the lens unit dependant attributes (that we currently know of or can deduce) include:
  • Image processing parameters
  • Noise reduction
  • Menu options - lens units define what menus you see
  • Distortion correction (and, presumably, other lens corrections)
  • Shutter speed and aperture ranges
  • Program mode parameters ('program lines')
  • Specific features (manual focus ring, sensor-shift stabilization etc)
  • Focus speed
  • Continuous shooting speed
  • Buffer (no of frames and speed)
  • Movie capture capabilities (resolution and frame rate)
