AT A GLANCENewly designed, super slim, high-performance GR lens
The GR IV incorporates a newly designed GR LENS 18.3mm F2.8, which delivers exceptional imaging performance with a slim design, while retaining the 28mm angle of view (equivalent in 35mm format) and large F2.8 maximum aperture. Consisting of seven optical elements in five groups, the latest optics incorporate glass-molded aspherical lens elements — including a large-diameter element used as a final lens — and high-refraction, low-dispersion glass elements to deliver high-contrast, high-resolution images with edge-to-edge sharpness, while minimizing distortion and chromatic aberration.High-quality, high-resolution images
To enhance image resolving power, reproduce rich gradation and upgrade sensitivity, the GR IV features a newly designed, back-illuminated APS-C-size CMOS image sensor for higher sensitivity and reduced noise with an upgraded GR ENGINE 7 imaging engine. With super-high-resolution images assured by approximately 25.74 effective megapixels and improved image processing performance, the GR IV produces exceptionally high-quality images rich in resolution and gradation. The GR IV also features the RICOH-original accelerator unit, designed to optimize the high signal-to-noise ratio image data captured by the image sensor and deliver it to the imaging engine, making it possible to assure top sensitivity of ISO 204800 for super-high-sensitivity photography..More advanced SR mechanism
The GR IV incorporates an updated version of the original SR (Shake Reduction) mechanism built into the camera body, enabling it to effectively compensate for camera shake at the time of shutter release. Assisted by a much-improved compensation algorithm, this five-axis mechanism minimizes adverse effects caused by pitch, yaw and roll during normal shooting, as well as shift shake during macro photography, by as much as six shutter steps.*
* The compensation effect of pitch, yaw, and roll: six shutter steps in the middle of an image, or four steps at edges, measured in conformity with 2024 CIPA standards.Compact, slim and functional body design
To improve the camera’s quick-shooting performance, the GR IV’s body has been redesigned to be compact, slim, and functional—key elements required in a snapshot camera. The body is slimmer than that of conventional GR-series models to assure a firm hold of the camera, while the thumb grip on the camera’s back is contoured to assure a tight but comfortable grip in the photographer’s hand.
The layout of control buttons and dials have been redesigned, while the mode adjustment (ADJ) lever has been changed to a dial type for ease of operation, making the GR IV more functional and accessible than ever before. The camera’s body frame is made of a lightweight, high-rigidity magnesium alloy to enhance durability and reliability during shooting and carrying.
New Cinema mode added to the Image Control function to expand the range of visual expressions
In addition to the 12 conventional effect modes of the Image Control function, the GR IV now features a new Cinema mode (with a choice of yellow or green tone), allowing the photographer to create an atmosphere reminiscent of nostalgic film-format movies of yesteryear. In addition to basic parameters such as Saturation, Hue, Key, Contrast and Grain Effect,* this new mode also lets the user adjust two other parameters—strength and size—to the desired level, making it possible to create more diverse visual expressions and choose the desired finishing touch best suited to a captured image. User-selected settings can be added to the Image Control menu as a custom mode.
