Built-in HDF (Highlight Diffusion Filter)

The built-in HDF (Highlight Diffusion Filter) diffuses highlights for softer light, creating more expressive images with a sense of depth and emotion.

It is designed to diffuse highlight areas and create a blurred effect along the image’s edges, making it possible to capture somewhat nostalgic images resembling those captured in film photography or vintage movies.

Select HDF with a press of a button

The HDF ON/OFF function can be quickly changed with a press of the Fn button on the back of the camera. “HDF” is printed near the Fn button.

* The Fn button can also be assigned to other function buttons.

Silver Shutter Release Button

The dark silver shutter-release button of RICOH GR III HDF subtly differentiates it from the standard RICOH GR III model. The appearance changes depending on the angle of light.

Pre-Program White-balance settings

Up to 3 custom white balances can now be registered. The base white balance and your own fine-tuned white balance can be assigned in combination.

*Note:  This function will be available for all RICOH GR III- and GR IIIx-series models using function-expansion firmware, which is scheduled to be released along with the market launch of the new RICOH GR III HDF and RICOH GR IIIx HDF.

Zone Select AF

Zone-select AF allows the user to select any zone within the 3×3 focusing area* and automatically focus on the appropriate position within the area.

*The 3×3 focusing area is similar in size to the existing “Auto-area AF (Center)”.

Note:  This function will be available for all RICOH GR III- and GR IIIx-series models using function-expansion firmware, which is scheduled to be released along with the market launch of the new RICOH GR III HDF and RICOH GR IIIx HDF.

High resolution and high contrast. Introducing the sharp imaging of the newly developed GR lens

The GR lens with a new lens construction was developed for even better image quality. This lens uses a slim optical system with six elements in four groups while maintaining the 18.3 mm (35 mm format equivalent: 28 mm) focal length and brightness of F2.8. High-refractive index, low dispersion glass and aspherical high-precision molded glass lenses are optimally placed in the lens construction to suppress 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 widest aperture setting.

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

This model is equipped with a high-resolution, wide dynamic range APS-C size CMOS image sensor (approx. 24.24 effective megapixels). It has approximately 1.5 times the pixels of the GR II and an anti-aliasing 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.

Advanced image processing and responsiveness. Meet the new GR ENGINE 6

The imaging processor on this model is the new GR ENGINE 6. It elevates the essential high image quality performance of the GR for an even greater level of detail. Faster processing makes a high pixel count image sensor and multi-level gradation in 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” has been adopted on this model 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 is installed while making the body size of the GR III more compact than its predecessor model. It minimizes the shake on three axes, including yaw, pitch and roll. Compensation effects deliver as many as 4 steps of shutter speed*.
*CIPA standard.

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. 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.
• Sufficient functionality may be achieved when the shutter speed is slower than 1/1000 second.

AA Filter Selector

Thanks to the built-in SR system, by using the microscopic vibration of the image sensor unit during image exposure, generates the same level of moiré-reduction effect as optical AA (anti-aliasing) filter. Unlike fixed optical AA filters which always creates the identical result, this innovative simulator allows the user to adjust the level of the moiré-reduction effect from OFF, Type1 and Type2. Bracketing of all those settings is also possible. Depending on your subject, you can chose high resolution shooting or AA filtered shooting.
