Ricoh GR IV - Demo Version

To further enhance the core strengths of the GR series—image quality, responsiveness, and compactness—this latest model in the series features a completely redesigned set of key components, including the lens, image sensor, and image processor. It features a newly developed APS-C format image sensor and a newly designed lens, which together improve image quality while reducing the body depth. This new concept was adopted from the predecessor model, the Ricoh GR III, and further refined. The newly adopted battery also contributes to extended battery life. To enhance operability and user-friendliness, the connectivity of this high-performance model has been further improved through an optimized interface with communication devices and new applications. 

Newly Developed, Ultra-Thin, High-Performance GR Lens
The GR IV is equipped with the newly designed GR LENS 18.3 mm F2.8, which combines exceptional image performance with a slim design while retaining the 28 mm angle of view (35mm equivalent) and the large maximum aperture of f/2.8 from the previous model. The optical system consists of seven lens elements in five groups and includes glass-molded aspherical lenses, as well as high-refractive-index, low-dispersion glass elements. This ensures high-contrast, high-resolution images with sharpness all the way to the corners, while minimizing distortion and chromatic aberration.

High-quality, high-resolution images
To enhance resolution performance, rich tonal gradation, and improved sensitivity, the GR IV combines a newly developed, back-illuminated APS-C CMOS image sensor—which offers higher sensitivity and lower noise—with an enhanced GR ENGINE 7 image processor. Thanks to approximately 25.74 effective megapixels and enhanced image processing, it delivers exceptionally high-quality images with high resolution and rich detail. The acceleration unit, originally developed by Ricoh, optimizes the signal-to-noise ratio of the sensor data and passes it to the image processor, enabling ISO values up to 204,800 for super-high-sensitivity photography.

Advanced Original SR Mechanism
The SR (Shake Reduction) mechanism integrated into the body effectively compensates for camera shake when the shutter is released. Using a significantly improved compensation algorithm, this five-axis mechanism corrects camera shake by up to six stops.*
* Measured in accordance with CIPA Standard 2024.

Advanced AF System with Reduced Power-On Time and Fast Autofocus
The redesigned lens barrel and optimized power-on sequence reduce the power-on time to approximately 0.6 seconds—the shortest in the GR series. This also simplifies switching to macro mode and retracting the lens, significantly enhancing the camera’s ability to capture images quickly. The fast lens drive and the sensor’s rapid data readout process also ensure fast focusing and improved autofocus precision. Overall performance has been optimized, particularly in low light and in terms of the accuracy and coverage area of the phase-detection AF system.

Compact, Slim, and Functional Body
To improve rapid shooting, the GR IV’s body has been completely redesigned to be compact, slim, and functional—the hallmarks of a snapshot camera. It is slimmer than previous GR models and ensures a secure grip. The rear thumb grip is ergonomically contoured. Controls have been rearranged, and the ADJ lever has been replaced with a rotary dial for easier operation. The body is made of a lightweight, sturdy magnesium alloy for greater durability and reliability when shooting and carrying the camera.

Quickly set the appropriate exposure mode
In Program Auto mode (Program AE), the GR IV offers the new Program Auto Ex function: The exposure mode can be instantly changed to Aperture Priority AE by turning the front control dial, or to Shutter Priority AE by turning the rear control dial. In addition, a Snap Distance-Priority AE mode has been added, which achieves deep depth-of-field effects by combining the subject distance in Snapshot mode with visual depth of field. This expands the selection of exposure modes. 

New Cinema Mode in the Image Control Function for Greater Visual Expression
In addition to the 12 conventional effect modes, the GR IV now offers a new Cinema Mode (yellow or green tint), which creates a rich, elegant atmosphere with a nostalgic film look. In addition to saturation, hue, brightness, contrast, and film grain, two new parameters—strength and size—can be adjusted to enable a wider range of visual expressions. User-defined settings can be added to the Image Control menu as a Custom Mode. Available Image Control modes: Monotone, Soft Monotone, Hard Monotone, High-contrast B+W, Negative Film, Positive Film, Cinema (Yellow), Cinema (Green)

Bluetooth® and Wi-Fi Dual Communication
The GR IV offers Bluetooth® and Wi-Fi for easy connection to smartphones and tablets. The GR WORLD app, developed specifically for the Ricoh GR series, facilitates communication such as image transfer to smartphones, remote shutter release, and location data transfer to smart devices.

High-resolution LCD display with excellent outdoor visibility
The GR IV features a 3.0-inch LCD with approximately 1,037,000 pixels. The design, which combines a resin-filled touch panel with reinforced protective glass, reduces reflections and light scattering and improves outdoor visibility. The “Outdoor Monitor Setting” function automatically adjusts the display brightness to the surroundings and also offers a convenient auto setting.

Additional features
- Anti-smudge and antistatic coating on the UV/IR blocking filter in front of the sensor, in addition to the conventional “DR II” ultrasonic dust removal system
- Full HD video recording (1920 × 1080, 60 fps) in H.264 format
-Customizable functions for the front and rear control dials as well as the exposure compensation button in a selected exposure mode, in addition to the ADJ. dial and Fn button
-RAW processing directly in the camera, with output as JPEG
-Built-in high-capacity memory with approx. 53 GB capacity
-Optional GW-4 wide-angle converter lens: expands the angle of view to 21 mm 35mm-equivalent
-Compatibility with the new, ultra-compact Ricoh GF-2 flash unit
-Crop modes for 35 mm (15 M) or 50 mm (7 M) KB equivalents
