Our take: If you prioritize physical handling and manual control accessibility, the GXR S10 edges out in ergonomics. For photographers valuing absolute portability and straightforward operation, the DP1’s compact footprint excels.

Sensor Technology and Image Quality - The Heart of Photography

Here’s where these two diverge significantly. Ricoh uses a 1/1.7" CCD sensor with 10 megapixels, while Sigma opts for a unique APS-C CMOS Foveon X3 sensor at 5 megapixels.

Technical Insights:

• The Foveon X3 sensor in the DP1 captures full color information per pixel by layering three photodiodes for red, green, and blue. That unique approach yields sharpness and color fidelity that often looks remarkable, despite the lower megapixel count.
• The GXR’s 1/1.7" CCD is smaller and uses a traditional Bayer color filter array, which can struggle with noise at higher ISOs.
• Physically larger sensor on the DP1 means better dynamic range potential, smoother gradations, and more control over depth of field.

Real-World Test Results:

• Ricoh GXR S10 produces crisp, clean images suitable for web, casual prints, and snapshots but begins to show noise beyond ISO 800.
• Sigma DP1’s images reveal superb detail in daylight and shaded environments but have limited flexibility in low light because of the capped ISO 800 ceiling.

Summary: If ultimate image quality and color accuracy are your benchmarks in good lighting, the DP1’s Foveon sensor is a compelling choice. For more general-purpose shooting with zoom flexibility, the GXR remains respectable, especially for snapshots and travel.

Lenses and Focal Lengths – Versatility vs Specialty

Lens choice is pivotal. The Ricoh GXR S10 comes equipped with a 24-72mm equivalent zoom lens (F2.5-4.4 aperture range), while the Sigma DP1 utilizes a fixed 28mm equivalent prime lens.

Ricoh Strengths:

• Versatile zoom range covers wide-angle to short telephoto - critical for travel, street, and everyday shooting.
• Optical image stabilization helps tame camera shake, vital at longer focal lengths and lower shutter speeds.
• Close focusing distance (1 cm macro) opens creative macro opportunities.

Sigma Strengths:

• Prime lens design yields superior image quality through simpler optics.
• Wide-angle prime focal length suits landscapes, environmental portraits, and street photography.
• In-lens design optimized specifically for their Foveon sensor.

Real-World Notes: The GXR’s zoom enabled us to swiftly frame portraits, landscapes, and candid shots without lens changes - perfect for on-the-go snapping. The DP1 demands you compose around its fixed wide angle, which can be transformative but limiting depending on your style.

Autofocus and Manual Controls - How You Capture the Moment

Auto-focusing speed and accuracy can influence success, especially in fast-paced scenarios.

Ricoh GXR S10 Notes:

• Contrast-detection AF is slow by modern standards, but continuous AF and multi-area options provide some flexibility.
• No face or eye detection - a downside for portrait work.
• Manual focus aided by on-screen magnification works decently for macro and landscapes.

Sigma DP1 Notes:

• Single AF mode only, roughly adequate for static subjects.
• No AF tracking or area selection - manual focus will be necessary for critical work.
• Live view supports magnified zoom for focus assistance.

Our assessment: Both cameras lag modern autofocus technology, so if you shoot fast-moving subjects like wildlife or sports, consider alternatives. However, for deliberate shooting such as landscapes, portraits, or studio work, manual focus combined with live view magnification remains a workable approach.

Body and Control Layout - Handling the Everyday Shoot

Understanding usability through body design and controls influences how swiftly and intuitively you create.
