Function Description
The RICOH GR III is a digital camera designed for still image and movie recording. It offers a range of shooting modes, including Program AE, Aperture Priority AE, Shutter Priority AE, and Manual Exposure, allowing users to control aperture value, shutter speed, and ISO sensitivity. The camera features various focus modes such as Auto-area AF, Select AF, Pinpoint AF, Tracking AF, Continuous AF, Manual Focus (MF), and Snap, with a focus distance range from approximately 0.06m in Macro mode to infinity. It also includes an internal ND filter for exposure control and a Shake Reduction (SR) system to reduce image blurring.
For image processing, the camera offers multiple "Image Control" settings like Standard, Vivid, Monotone, Soft Monotone, Hard Monotone, Hi-Contrast B&W, Positive Film, Bleach Bypass, Retro, and HDR Tone, allowing users to customize the image atmosphere. It supports D-Range Correction for highlight and shadow areas and Noise Reduction for both slow shutter speeds and high ISO sensitivities.
Playback functions include displaying single or multiple images, rotating images, and connecting to AV devices. Users can edit and process images directly on the camera, including RAW development, resizing, cropping, levels adjustment, white balance correction, color moiré correction, and base parameter adjustments. Movie editing functions allow for cutting and dividing movie files.
The camera's settings can be customized extensively, including saving frequently used settings to the mode dial (USER1, USER2, USER3), customizing button functions (ADJ. lever, Fn button, ISO button, Drive button, Movie/Wireless button), and configuring display and sound settings. It also has power-saving features like auto power-off and display dimming.
Connectivity options include USB for computer connection, Bluetooth® for communication with smart devices, and Wireless LAN for image transfer and remote control via the "Image Sync" app.
