Key functions such as shutter speed, aperture priority mode, and exposure compensation are accessible, yet the menu system and button feedback lack refinement observed in later generations. The GR IV does not include a touchscreen or illuminated buttons, indicators of its 2011 heritage.

Conversely, the RX10 III features a sophisticated, SLR-like control scheme including dedicated dials for shutter speed, aperture, exposure compensation, and an FM/AEL button cluster. The rear LCD articulates with a tilting mechanism ideal for low and high-angle shooting. Although the RX10 III lacks a touchscreen, it includes a bright electronic viewfinder (EVF) offering 2.36 million dots and 100% coverage, an essential usability improvement absent on the Ricoh. These thoughtful interface elements facilitate rapid settings adjustment and make the RX10 III an easier proposition for workflow-intensive shooting.

While the Ricoh prioritizes straightforwardness and portability, the Sony seeks to enable more complex shooting scenarios with tactile control access and enhanced visual feedback.

Sensor and Image Quality: Small CCD vs Large 1" BSI-CMOS Sensor Advantage

A fundamental differentiation lies in the imaging sensors:

• Ricoh GR Digital IV: 1/1.7" CCD sensor, 10 megapixels (3648 x 2736), with 7.44x5.58 mm dimensions (41.52mm²), native ISO 80-3200, and traditional anti-aliasing filter.

• Sony RX10 III: 1" BSI-CMOS sensor, 20 megapixels (5472 x 3648), with 13.2x8.8 mm dimensions (116.16mm²), native ISO 125-12800 (boostable to 25600), also with an anti-aliasing filter.

CCD sensors, such as the one in the Ricoh, historically emphasize color depth and low noise at base ISO, but their smaller size and older technology restrict dynamic range and noise performance as ISO rises. The GR IV’s AA filter avoids moiré at some expense to utmost sharpness but still delivers excellent JPEG output with rich midtone subtlety, ideal for careful post-processing or JPEG-first workflows. Raw support enhances latitude, though workflow demands are simplified by the 10MP resolution and limited burst capability.

The Sony’s back-illuminated CMOS sensor is more advanced, offering significantly higher resolution and notably improved dynamic range (measured DxO dynamic range of 12.6 vs Ricoh’s untested but modest expectations), better high ISO usability with low noise (DxO low light ISO rating 472), and faster readout enabling 14fps burst shooting. The larger sensor area enables superior bokeh control and more effective background separation, critical for portraits and wildlife.

Pragmatically, the RX10 III yields technically superior files with greater editing flexibility and noise resilience. The GR Digital IV excels for photographers valuing compactness, color fidelity, and prime sharpness over sensor prowess.
