The WG-5 GPS leverages a 1/2.3" BSI-CMOS sensor of 16 MP resolution, physically measuring 6.17 x 4.55 mm with a nominal area of 28.07 mm². This sensor type is optimized for quick signal readout and improved noise performance within the compact form factor. However, the physical limitations of such a small sensor impact dynamic range and high ISO cleanability.

Conversely, the Sigma DP2 Quattro centers its imaging capabilities around a unique APS-C sized CMOS sensor with Foveon X3 technology, physically measuring 23.5 x 15.7 mm and offering 20 MP effective resolution through layered chromatic capture. The sensor area is an impressive 368.95 mm², enabling substantial light-gathering and detailed image rendition.

In terms of image output, the Ricoh WG-5 GPS offers a maximum resolution of 4608 x 3456 pixels (approximately 16 MP), supporting JPEG formats exclusively - raw capture is unsupported, thus limiting post-processing latitude. It features an anti-aliasing filter to combat moiré.

The Sigma DP2 Quattro yields larger images at 5424 x 3616 pixels, with lossless compressed raw files supported. This offers immense potential for detail retention, color depth, and nuanced tonal gradation critical to professional workflows. The Foveon sensor's architecture means that color data is captured at every pixel depth level, theoretically producing superior color accuracy and sharpness compared to Bayer-pattern sensors.

Despite its innovation, the DP2 Quattro lacks image stabilization, which can impact low-light usability, whereas the WG-5 GPS employs sensor-shift stabilization mitigating camera shake across focal lengths.

In practice, the Ricoh’s sensor excels in providing vibrant output for on-the-go snapshots with limited post-processing, particularly in well-lit conditions. The Sigma’s sensor dominates in studio, landscape, and fine art photography where maximum detail and tonal fidelity are paramount but requires a tripod or steady hand due to stabilization absence and slower continuous shooting speeds.
