Expanded functionality firmware for an ever-evolving GR IIIx HDF

The GR IIIx HDF keeps evolving with the latest firmware updates. The expanded functionality firmware is provided to add new features and setting operations.


New Features

The following functions are now available with the GR IIIx HDF:
- The user can preprogram up to three white-balance settings as the base white balance. It is also possible to couple the base white balance with the White-balance Fine Adjustment function.

- The new model feature Zone Select AF, which automatically sets the focus at the most ap-propriate point within the image area, after the user shifts the 3x3 focus area to the desired zone. The 3x3 focus area is identical in size to that of the Auto-area AF (Center) mode.





Image Performance without compromise


The RICOH GR IIIx HDF is equipped with the newly designed 26.1mm GR lens, provides a 40mm angle of view in the 35mm format, close to the photographer’s own effective field of view. 

It is also designed to further enhance the essential values of the GR-series: optimizing image quality, snapshot capabilities and portability.


The detailed descriptive power of the 24.2 M large APS-C format image sensor


The GR III models are equipped with a high-resolution, wide dynamic range APS-C format CMOS image sensor (approx. 24.24 effective megapixels). High resolution sensor which can handle a large size print and an anti-aliasing (AA) filterless construction that utilizes the characteristics of the high-resolution lens for high-definition detail reproduction. Both the image sensor and lens are also optimized for the best possible image quality.


The new GR lens achieves sharp imaging with high resolution and high contrast


The GR lens has been imbued with our unique optical technology that aims to always provide high image quality. The GR III uses a slim optical system consisting of 6 elements 4 groups with a focal length of 18.3 mm (approx. 28 mm in 35 mm equivalent focal length) and aperture of F2.8. The GR IIIx uses a newly developed optical system consisting of 7 elements 5 groups with a new focal length of 26.1 mm (approx. 40 mm in 35 mm equivalent focal length). High-refractive index low-dispersion glass lenses and aspherical high-precision molded glass lenses are optimally placed in the lens construction according to each model’s optical system to suppress optical distortion and chromatic aberration to the absolute limit, delivering a high level of sharpness. This results in images that are sharp and clear across the entire frame even from the full aperture setting.



Advanced image processing and responsiveness.

Meet the latest GR ENGINE 6

The imaging processor on GR III models is the latest GR ENGINE 6. It elevates the essential high image quality performance of the GR for a greater level of detail. Faster processing makes the combination of high resolution sensor and multi-tone 14-bit RAW possible. This also contributes to improved responsiveness and functionality for autofocus and movie. 


Shooting at ISO 102400 is possible with our original signal processing technology

A high-performance processor "Accelerator Unit" is adopted on GR III models as a powerful way to support high image quality. The signal output by the image sensor is sent to the image processor after being optimally handled. This reduces noise, delivering superb resolution and color reproduction across the entire sensitivity range. It also makes it possible to shoot at ISO 102400.

3-axis, 4-step Shake Reduction for high image quality across a wide shooting range

Camera shake is reduced for crisp images even when taking split-second snapshots. Shake Reduction(SR) is installed while making the body size of GR III models compact. It minimizes the shake on three axes, including yaw, pitch and roll. Compensation effects deliver as many as 4 steps of shutter speed*. * Measured in conformity with CIPA standards.

AA filter simulator for reducing false colors and moiré thanks to Shake Reduction mechanism

The effects of the optical anti-aliasing (AA) filter are obtained with Shake Reduction(SR). Moving the image sensor slightly during the exposure suppresses false colors and moiré. You can choose whether to prioritize resolution or reducing false colors and moiré depending on your subject. Choose [High] or [Low] for effect settings.

● This function is available at shutter speeds slower than 1/1000 second.




A compact body and functional design packed with high performance


The GR III models are developed focusing on keeping the body size compact while including a high level of functionality. The model is one-size smaller than that of the GR II and about the same size of GR DIGITAL IV with a 1/1.7 inch image sensor. A minimalist design was pursued to achieve a tool with portability and expression in mind. The button and dial layout is fully considered to allow for comfortable, single-handed operation.




Hybrid AF with the combination of image plane phase-matching and contrast-detection AF


The AF system is a hybrid of image plane phase-matching and contrast detection. The advantages of high-speed focusing in image plane phase-matching AF and focusing precision in contrast-detection AF are combined. The common contrast-detection AF issue of searching for focus peaks has been reduced to achieve quick shooting performance required on street photography.



High-speed approx. 0.8 second start-up from when the power is turned on

A high output motor is used to drive the lens barrel so that it quickly moves from a retracted position to the shooting position. Also, the program process of start-up is optimized to reduce the start-up time. The built-in lens barrier also makes it unnecessary to remove the lens cap, so you will not miss a sudden photo opportunity.



Focus modes that fit versatile subjects and shooting styles

Eight focus modes are available including Continuous AF for versatile shooting styles. LCD monitor that supports touch operations is also adopted for direct control over the AF frame using touch and slide gestures. You can also focus (Touch AF) and shoot while moving the AF frame for quick shooting in any type of composition.



Face/eye detect autofocus to assist portrait shooting

The camera detects faces or eyes* and focuses. This feature is enabled in [Auto Area AF], [Select AF], and [Pinpoint AF]. When the face or eye is detected and in-focused, the focusing point is framed. It is also possible to enable this feature only in [Auto Area AF]. By using this setting, when you want to focus on a subject instead of faces, simply switch the focus mode without turning face/eye detect off.



With Full Press Snap, you'll never miss a shot

When the shutter button is pressed fully, the camera releases the shutter at the preset distance. This high-speed shooting functionality is unique to the GR, eliminating the focusing time lag when pressing the shutter button halfway so that you can instantly capture split-second moments. Full Press Snap also takes place by touching the LCD monitor. *The latest firmware is required to use the full feature with GR III. Click here for more details.



Touch panel and control dial that enables intuitive controls

The LCD monitor features a touch panel. Simply touch and slide to move the AF frame or access the menu. You can also pinch in and out during playback to change the magnification, flick to view the previous and next images or even go back to the center of the image by double tapping the monitor. A control dial is also positioned around the four-way button. This layout makes it possible to quickly operate the camera with a simple action while maintaining a secure grip on the camera.



Customizable functions to suite one’s style

ADJ. mode and Fn button functions are customizable. You can also save the camera settings that best match your shooting intentions or the subject to U1/U2/U3 on the mode dial, making controls more convenient to match your shooting style.
