Incorporating a newly developed highlight diffusion filter (HDF), the Ricoh GR III HDF allows users greater control over the style of their imagery while maintaining exceptional image quality. Captures with HDF enabled are noticeably softer and feature an emphasize on highlights, resulting in a more nostalgic look that resembles film photography or vintage movies. The default setting of the Fn button is to turn HDF on or off. This model also features a dark silver shutter-release button to distinguish itself from previous GR series models. Lastly, new firmware allows Zone Select AF as well as up to three white-balance settings to be preprogrammed as the base white balance.

HDF Model Enhancements
Dark silver shutter-release button
HDF on/off is assigned to Fn button by default but can be assigned to other function buttons
Up to 3 custom white balances can be registered
Zone-select AF allows users to select any zone within the 3x3 focusing area
24.2MP APS-C CMOS Sensor and GR Engine 6
Featuring an updated design, a 24.2MP APS-C CMOS sensor pairs with a new GR Engine 6 to produce high-resolution 14-bit DNG or JPEG stills with impressive tonality, natural color rendering, and high sensitivity from ISO 100-102400. In addition to full-resolution, wide-angle images, a pair of useful crop modes—35mm at 15MP and 50mm at 7MP—let you simulate the look of working with longer focal lengths.

In addition to stills shooting, the GR III HDF is capable of recording Full HD 1080 video at 60p, 30p, and 24p frame rates.

Prime Wide-Angle Lens
A fixed prime 18.3mm lens offers a comfortable 28mm equivalent wide-angle lens, which is complemented by a bright f/2.8 maximum aperture to suit working in a variety of lighting conditions. The optical construction incorporates six elements in four groups, including two aspherical elements that help to reduce spherical aberrations and distortion for improved sharpness and accurate rendering. Two focusing modes also suit working with general subjects, from 3.9" to infinity, while a dedicated macro setting benefits working with close-up subjects within a 2.4-4.7" range. An internal two stop-effective (ND 0.6) filter is also available for either slowing the shutter speed or permitting working with a wider aperture setting, and the lens has a nine-blade diaphragm to contribute to a smooth bokeh quality. Additionally, the redeveloped lens design also results in greater contrast and is 1.5mm thinner than previous GR/GR II digital cameras.

Shake Reduction System
Featured for the first time in a GR camera, a 3-axis Shake Reduction System helps minimize the appearance of camera shake in order to promote sharper handheld shooting at slower shutter speeds. The Shake Reduction System has been optimized for use with the built-in 28mm-equivalent lens, which renders it smaller and more effective. Additionally, the SR unit also offers moiré reduction and dust removal capabilities.

Body Design
The hallmark feature of the GR-series has been its compact, pocketable size while still retaining a large image sensor and bright prime lens.
Integrated 3.0" 1.037m-dot LCD features a capacitive touchscreen design for intuitive, familiar operation during shooting, playback, and menu navigation.
The rear layout of the camera has been completely redesigned and prioritizes a larger, more comfortable thumb grip along with easily accessible physical dials. Additionally, the ADJ lever, FN button, and Touch AF operations can be programmed to handle specific assignable functions for more personalized control.
Start-up time has been reduced to 0.8 sec and Hybrid AF performance has been quickened for more seamless operation.
Integrated Bluetooth LE and Wi-Fi afford wireless connectivity between the camera and a paired mobile device, allowing you to embed location info within your files as well as transfer files to your mobile device, even when the camera is turned off.
Included DB-110 rechargeable lithium-ion battery offers approximately 200 shots per charge.
USB-C port allows you to transfer files or recharge the battery in-camera.
