Get inspired to capture expressive photos with enhanced imaging power

Designed to further enhance the essential values of the GR-series—optimizing image quality, responsiveness, and portability— the RICOH GR IV features a newly developed back-illuminated APS-C-size CMOS image sensor for higher sensitivity and reduced noise with the new GR ENGINE 7 imaging engine. The newly designed GR LENS delivers exceptional imaging performance. The lens barrel and optimized start-up sequence reduce the start-up time to approximately 0.6 seconds— the shortest in GR-series history!

The GR IV’s body has been thoroughly redesigned, offering enhanced performance in a compact and slimmer body, while layout of control buttons and dials have been redesigned, improving the camera’s functionality. It delivers high-quality, high-resolution images with intuitive, responsive snapshot operation, making it an excellent choice for snapshot photography.

Imaging Power, One Step Ahead

The lens, image sensor, and image processing engine have all been reinvented.
Get inspired to capture expressive photos with this enhanced imaging power.

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.
