Now equipped with an external autofocus sensor developed in-house that
allows for high-speed, high-precision distance calculations for up to 190
points. Thanks to a hybrid autofocus system used in combination with a
contrast autofocus, an autofocusing time of as short as 0.2 seconds, as much as
half that of the GR DIGITAL III, has been achieved. Furthermore, algorithm
refinements have also led to the realization of a maximum of approximately
twice the speed with macro autofocusing that uses only contrast AF. The
camera can also use the external autofocus sensor when you press the shutter
release button all the way down in one motion for Snap or Full Press Snap*.
You can capture the moments you want with crystal clarity thanks to the
combination of great precision of focus with superb responsiveness.
Quick shooting capabilities combined with precision focus.

*Focus distances available for selection includes Auto, 1 m, 1.5 m, 2.5 m, 5 m, and .
The first model in the GR DIGITAL series equipped with an image sensor shift
image stabilization feature. Useful for dark scenes and for using Full Press
Snap when blur is a concern. The stabilization effect amounts to as much as 3.2
steps calculated in terms of shutter speed.
Improved performance in dark scenes.
Image stabilization feature
*Measured using RICOH measurement methods.
*White pixels were added to RGB to attain approximately 1.23 million dots.
Maximum brightness for the image monitor increased approximately 1.7
times that of previous models (compared to the GR DIGITAL III). Brightness
can be adjusted automatically in accordance with the brightness of the
subject. It helps with taking
snapshots even in the bright
outdoors owing to its superb
visibility.In addition, the distance
information calculated by the
external autofocus sensor can
now be displayed as necessary,
helping to improve convenience
and comfort level.
Visibility improved at high brightness.
New 3-inch image monitor with approximately 1.23 million dots*.
