GR IV Camera

Newly 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 camera also features the RICOH-original accelerator unit, designed to optimize the high signal-to-noise ratio image data captured by the sensor and deliver it to the imaging engine, making it possible to achieve 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.

Advanced AF system with reduced start-up time and high-speed autofocus operation

The GR IV’s newly designed lens barrel and optimized start-up sequence reduces the start-up time to approximately 0.6 seconds—the shortest in GR-series history. This combination also reduces the time required for switching to the Macro shooting mode and during lens-storage action, greatly enhancing the camera’s quick-shooting capabilities. The high-speed lens driving mechanism and the image sensor’s high-speed data readout assure high-speed focusing operation and improve autofocus precision. Autofocus speed in low-illumination ranges, as well as precision and coverage of the image-plane phase-matching AF system, have also been optimized to improve overall AF performance.

Compact, slim and functional body design

To improve quick-shooting performance, the GR IV’s body has been redesigned to be compact, slim, and functional—key elements for a snapshot camera. The body is slimmer than previous GR-series models to assure a firm hold, while the thumb grip on the back is contoured for a tight but comfortable grip. The layout of control buttons and dials has been redesigned, and the mode adjustment lever (ADJ) has been changed to a dial-type for ease of operation. The body frame is made of lightweight, high-rigidity magnesium alloy to enhance durability and reliability.

Quick setting of the desired exposure mode

When the camera’s exposure mode is set to Program AE, the GR IV features a new Program Auto Ex function, which allows the photographer to instantly shift the exposure mode with a simple turn of the front e-dial to Aperture-Priority AE or the rear e-dial to Shutter-Priority AE. A Snap Distance-Priority AE (Sn) mode has also been added, allowing the photographer to capture images with an emphasized depth of field, based on the combination of subject distance and depth-of-field effect.

New Cinema mode in Image Control function

In addition to the 12 conventional effect modes of the Image Control function, the GR IV now features a Cinema mode, with a choice of yellow or green tone, allowing photographers to create an atmosphere reminiscent of nostalgic film-format movies. This mode allows adjustment of strength and size in addition to basic parameters such as Saturation, Hue, Key, Contrast, and Grain Effect, providing greater creative flexibility. User-selected settings can be added to the Image Control menu as a custom mode.

High-definition LCD monitor with outstanding outdoor visibility

The GR IV features a 3.0-inch high-definition LCD monitor with approximately 1,037,000 dots. It incorporates an air-gapless construction, in which special resin is placed between the touch-screen panel and the protective cover made of reinforced glass, reducing reflection and light dispersion for improved visibility outdoors. The Outdoor Monitor Setting ensures visibility in both bright outdoor and low-light indoor conditions. The new Auto setting automatically adjusts brightness based on the surrounding lighting.

Bluetooth® and wireless LAN dual communication

The GR IV provides a dual-communication system combining Bluetooth® and wireless LAN for easy pairing with smartphones and tablets. Exclusively designed for the RICOH GR series, the GR WORLD application simplifies a variety of communication operations, including image transfer to a smartphone, remote shutter release, and transfer of location data.
