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. 

Hybrid autofocus system

*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.
