Ricoh GR IV Digital Camera

A Fusion of Tradition and Innovation.
The New GR Lens

Lenses that capture light are the most important elements in ensuring high image quality. It was this idea that resulted in the new 18.3mm (28mm in 35mm equivalent focal length) F2.8 GR lens. Driven by our conventional design concepts and incorporating innovations in optical technologies, we added a large, aspherical high-precision molded glass lens as the final lens in a 5-group 7-element construction. Effective aberration correction improves sharpness from the center area of the frame to the edges. Also, optimal placement of high-refractive index low-dispersion glass lenses and aspherical molded glass lenses which are made possible by ultra high-precision manufacturing technologies result in a slim lens unit. We also developed a new lens barrel that contributes to a shorter start-up time and faster AF.

High-sensitivity and Low-noise Back-illuminated Sensor.
25.7M CMOS Image Sensor

Accurate reproduction, rich tones, and high-sensitivity performance. To enhance each of these areas, the GR IV uses a back-illuminated APS-C size equivalent CMOS image sensor (approx. 25.74 million effective pixels). This makes it possible to fully utilize all of the light collected by the new GR lens with high sensitivity and low noise. In addition, a new UV/IR protection filter has been developed for the front surface of the lens. In particular, by enhancing the permeability on the long wavelength side, the amount of incident light to R pixels has been increased, improving color reproduction.

Advanced Imaging Power and Mobility. GR ENGINE 7

The new GR lens and image sensor deliver a wealth of information and the new GR ENGINE 7 uses it to the full in images. Improved image processing capabilities enable delicate, realistic reproduction of details. In addition, faster processing speeds improve camera response times, including AF. These features enhance the high image quality and mobility required of a snapshot camera.

Expand the Realm of Possibilities.
ISO 204800

The GR IV features better high-sensitivity performance with a maximum setting of ISO 204800. You can now flexibly set the sensitivity according to your shooting style. High SN ratio signals output from the back-illuminated image sensor are optimally processed on our original accelerator unit and then sent to the GR ENGINE 7. The flexibility of the sensitivity settings expands the possibilities of expression.

Powerful Snapshot Capabilities.
5-axis, 6-step Image Stabilization

The camera detects shaking even during sudden snapshots. The image sensor instantly activates to correct camera shake. The GR IV features 5-axis image stabilization. In addition to conventional angular and rotational blur, it also corrects shift blur, which tends to be noticeable during close-up shooting. A fully developed correction algorithm delivers enhanced performance up to 6.0* steps when converted to shutter speed.

* Up to 6.0 steps at the center, and up to 4.0 steps on the periphery. CIPA 2024 standard compliant. Yaw/Pitch/Roll correction performance.

Faster, More Precise. AF Performance

The GR IV offers superb imaging that is similar to how the human eye sees. Its AF performance has also advanced significantly. AF speed has been improved thanks to faster lens drive with the new lens barrel and faster readout with the new image sensor. The AF algorithm has also been tuned for more precise focusing. Furthermore, we have also incorporated various other AF innovations, such as improved AF performance in low-light scenes and better subject detection across a wide area thanks to image plane phase difference.

Camera-assisted Portraits.
Face/Eye Detection AF

The camera detects faces and eyes for automatic focusing. Once a face or eyes are detected, a frame is displayed. When multiple people are detected, simply touch the face of the one you want to focus on to move the AF point. This feature is enabled during shooting with [Auto-area AF], [Zone Select AF] [Select AF], or [Pinpoint AF].

Finely Honed Responsiveness.
approx. 0.6 second High-speed Start-up

Simply pick up the camera and you are ready to shoot. The new lens barrel and optimized start-up sequence gives the GR IV the fastest start-up time of the GR series at approx. 0.6 second. Other operation times are also faster, including switching to the macro mode and retracting the lens after shooting for more responsive shooting.

A Unique GR Quick Shooting Feature.
Full Press Snap

The GR IV is equipped with the “Full Press Snap” function that allows you to instantly shift the focus to a preset distance by simply pressing the shutter release button fully. This unique GR feature eliminates the focusing time lag when the button is pressed halfway, allowing you to shoot instantly. Responsiveness in dark areas has also been improved so you will never miss split-second photo opportunities whether shooting at night or in dark locations.

Smoother Focusing.
Focus Limiter

You can limit the focusing distance according to the shooting theme, enabling smooth focusing. “Focus Limiter” can be set to [Near Side], [Far Side], or [Off]. [Near Side] is effective for shooting closer subjects when you want to keep the AF from switching to the background. [Far Side] is useful for keeping AF from focusing on objects and people in the foreground when taking general snapshots.

Easier Snapshots.
Sn Mode

The Sn mode (Snap Distance Priority AE) has been added to the mode dial. This allows you to shoot at the set snap focus distance and depth of field. The depth of field can be adjusted in three levels, allowing you to easily enjoy expressions that emphasize depth in combination with the snap focus distance.

Even Easier AE.
Program Auto Ex

The GR IV is equipped with the “Program Auto Ex” function. Even when shooting in “Program AE,” turning the front e-dial instantly switches to “Aperture Priority AE,” and turning the rear e-dial seamlessly switches to “Shutter Priority AE.”
