Used RICOH GR DIGITAL IV CAMERA WHITE SE

GR DIGITAL IV digital camera, the successor model to the GR DIGITAL III, which offers enhanced Quick Shooting capability and image quality.

The GR DIGITAL III (released in August 2009) was a compact digital camera with high image quality that came with a 28mm/F1.9 GR Lens, the GR ENGINE III, and a high-sensitivity CCD that continued the evolution of the concepts originally introduced in the first GR DIGITAL model (released in October 2005). In the two years since its release, it has been enthusiastically received by a broad range of customers including professional and amateur photographers.

The new GR DIGITAL IV, featuring a new image engine and a refined optical filter, exceeds the GR DIGITAL III and achieves the highest level of image quality in the history of the GR series.

Additionally, for the advancement of the Quick Shooting capabilities required to make sure you never miss a shot when out shooting, Ricoh has introduced a Hybrid AF System and an Image-sensor-shift Image Stabilization Function, which makes use of Ricoh's independently developed external AF sensor, and a 3-inch, approximately 1.23 million-dot VGA LCD monitor for heightened outdoor visibility. The addition of an electronic level that can detect inclination in the tilt direction, as well as the conventional horizontal direction also improves operability. Moreover, the inclusion of Dynamic Range Compensation makes it possible to shoot subjects in backlit or high-contrast scenes in the way the eye sees them, and Interval Composite, which can combine images shot at a certain shooting interval, advances the camera's expressive capabilities.

Ricoh will also continue to provide the highly praised function-expansion firmware.

Main Features of the GR DIGITAL IV
Improved AF speed and accuracy due to the introduction of the Hybrid AF system
The camera comes newly equipped with Ricoh's independently developed external AF sensor, which has a maximum of 190 AF points. Through the Hybrid AF System, which is used in parallel with the conventional CCD contrast AF, Ricoh has realized an AF focusing time as short as 0.2 seconds, as much as half that of the GR DIGITAL III.

Also, algorithm refinements have led to improvements in the AF speed for macro shots that are taken using only the CCD contrast AF method for a maximum reduction of half the time of the previous model.

In shooting with a single press of the shutter-release button, the high focusing accuracy required for snapshot shooting has been added to the camera's Quick Shooting capabilities by performing the metering with only the external AF sensor. The metering information from the external AF sensor can be displayed on the LCD monitor as necessary.

Even higher image quality achieved
Through refinements to the optical filter and optimization of the image processing from the previous model, the GR DIGITAL III, theSFR* characteristics have been improved.

With the new image processing engine, the GR ENGINE IV, color reproduction enhancement and color noise reductions are achieved whentaking high-sensitivity photographs.

Ricoh's signature 28mm/F1.9 GR lens demonstrates its high resolution while suppressing chromatic aberration and distortion. The approximately 10 million-pixel, 1/1.7-inch CCD shows off its high-sensitivity characteristics. These are the elements through which the GR DIGITAL IV achieves the highest image quality in GR DIGITAL history.

* Spatial Frequency Response (SFR): One of the indicators of a digital camera's resolution characteristics, including everything from the optical system to the image processing.

Comes with the first image-sensor shift image stabilization function in the GR DIGITAL series
With the image-sensor shift image stabilization function, the GR DIGITAL IV achieves a stabilization effect equivalent to a shutterspeed increase of a maximum of 3.2 stops*, which combined with the fast F1.9 GR lens further increases the camera's ability to capture dark scenes.
*Measured using RICOH measurement methods.

Introduction of a new, high-brightness LCD monitor and the addition of an automatic brightness adjustment function
Through the introduction of the new 3-inch, approximately 1.23 million-dot VGA LCD monitor, which adds white pixels to the RGB ones, the GR DIGITAL IV secures a maximum brightness of approximately 1.7 times that of the GR DIGITAL III, improving its visibilitywhen outdoors.

A function in which the camera automatically adjusts the luminance to match the brightness of the subject has been added, which minimizes decreases in visibility due to changes in the shooting environment.

Shooting functions that heighten the photographer's expressive ability and enhanced scene modes
Comes with dynamic range compensation to minimize the effects of blown highlights in bright areas and crushed blacks in dark ones. For backlit or high-contrast scenes where exposure compensation alone is not enough, compensation is performed for each area, enabling the photographer to take pictures at a brightness that closely matches how the subject looked.

The Auto Bracket function has been enhanced. In addition to the conventional Exposure and White Balance, Contrast Bracket Setting and Dynamic Range Compensation bracketing have been newly added, of which any two can be selected for addition to the image settingsto record a sequence of three shots with Image Setting Bracket

Comes with an Interval Composite mode that will replace and combine only the high-brightness pixel data in images of the night sky taken at fixed intervals. This makes it possible to shoot distinctive landscape pictures that show the trails of light left by the stars.
