This model is equipped with a new GR lens that surpasses all other GR lenses with its amazing optical performance. A six-element, four-group optical system is used to achieve images that are sharp from the center to the edge with clear depiction. The optical system is slim and compact so the body can accommodate an in-camera Shake Reduction mechanism. The effects of camera shake on image quality are minimized and the full capabilities of the newly designed GR lens optical performance are maximized for a variety of scenes.
Approximately 24.24 effective megapixels deliver high image quality, and an anti-aliasing filterless construction delivers high-definition rendering even in the finest details.
Original noise reduction processing results in high image quality even at high ISO sensitivity. 14-bit RAW recording is also supported for rich tonal reproduction.
A newly developed imaging processor delivers further improvements in high image quality performance, elaborately detailed imaging across the entire sensitivity range, and superb color reproduction.
Image plane phase-matching AF delivers high-speed AF and contrast-detection AF offers superb focusing precision. The best of these two types are combined to make a hybrid AF. The common issue of searching for focus peaks in contrast-detection AF has been significantly reduced on this model. The hybrid system delivers faster autofocus and greater precision.
This model uses the sensor-shift type, Shake Reduction mechanism. It delivers compensation on three axes.
*Shutter speed conversion. CIPA standard.
The camera is equipped with an LCD monitor that supports touch operations and a convenient control dial. These features provide quick control over AF frame movement and menu access.
The body size of this model is about the same as the GR DIGITAL IV (model with a 1/1.7 type image sensor) while delivering a completely new dimension of performance for the GR series. Controls are improved while maintaining the pursuit of portability, bringing us one step closer to the ultimate snapshooter.
Expanded functionality firmware for an ever-evolving GR III
The GR III keeps evolving with the latest firmware updates. The expanded functionality firmware is provided to add new features and setting operations.
Frequently used functions can be assigned to the ADJ lever and Fn button. Other controls can also be customized for fine tuning camera operation, making the camera easier to use and to match your shooting style.
Image Control & JPEG image adjustment
The GR III features many selections of advanced image creation functions. Image adjustment parameters have been redesigned to 10 Image Control options for shooting. During playback, image tones of JPEG can be adjusted and saved as a new file.
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.

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.
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.
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.

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 raw. Compensation effects deliver as many as 4 steps of shutter speed*.
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.

The GR III was developed with a focus on keeping the body size compact while including a high level of functionality. This 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 type 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.
The AF system is a hybrid of image plane phase-matching and contrast detection. The advantages of image plane phase-matching AF high-speed focusing and contrast-detection AF focusing precision are combined. The common contrast-detection AF issue of searching for focus peaks has been reduced for quick shooting performance required on a snapshot camera.
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, optimized program processing during start-up reduces the start-up time. The built-in lens barrier also makes it unnecessary to remove the lens cap, so you will never miss a sudden photo opportunity.
