Sigma DP1 vs. Sigma DP2s: A Thorough Comparison for Serious Photographers

When stepping into the realm of large sensor compact cameras, Sigma’s DP series represents a distinctive approach to image quality, merging medium-format technology with compact form factors. Today, we dive deep into the Sigma DP1 and its successor, the Sigma DP2s, to help you understand their nuances and decide which might suit your creative vision best.

Both cameras champion the Foveon X3 sensor system, delivering vibrant color and detail unlike conventional Bayer sensors. Yet, the DP2s brought incremental upgrades over the DP1 that impact various facets of shooting experience and image performance. Having tested these cameras extensively in diverse environments, from controlled studio portraits to demanding outdoor wildlife shoots, we offer you a grounded, experience-driven comparison.

Getting Oriented: Design and Handling Differences

Both models share a compact body design geared for photographers who crave large sensor quality without hauling heavy DSLR rigs. Here’s how they compare in physical ergonomics and control layout:

The DP2s is marginally thicker and heavier due to a more complex True II processor and added features. Both lack electronic viewfinders, demanding reliance on the fixed rear LCD for composition. While the fixed lens design limits zoom flexibility, the handling remains practical for street, travel, and landscape shoots where mobility is key. We recommend testing the grip ergonomics personally - especially if your shooting includes longer handheld sessions.

Sensor Technology and Image Quality: The Heart of Sigma’s Foveon Innovation

Both cameras employ the APS-C sized Foveon X3 sensor with a resolution officially listed as 5 megapixels. The sensor’s unique layered design captures full color at every pixel site, delivering richer detail and color accuracy - especially in controlled lighting.

Despite the identical sensor size and baseline resolution, the DP2s extends the ISO range significantly, enabling better low-light versatility. The True II processor in the DP2s enhances noise reduction and image processing speeds without compromising the sensor’s signature clarity.

This makes the DP2s a better choice if you expect to shoot in varied lighting, such as indoor portraits or evening street photography.

Focus and Exposure Controls: Precision in Manual and Contrast Autofocus

Both cameras emphasize manual focus with no autofocus points - their AF system relies on contrast detection limited to center-weighted metering. Here’s a breakdown:

• Sigma DP1: Manual focus only, no continuous or face detection autofocus.
• Sigma DP2s: Manual focus supported with contrast-detection AF, single AF mode only, no tracking or face detection.

The DP2s’s contrast-detection AF is a modest improvement for quicker lock-on in good light but still cannot match phase-detection systems in speed or tracking, notably in wildlife or sports.

Exposure modes on both include shutter priority, aperture priority, and manual exposure - offering flexibility for creative control. Custom white balance is only available on the DP2s, allowing finer color control in mixed lighting.

For critical macro or portrait work where focus precision is key, both require disciplined manual focusing. The DP2s's more sensitive metering and exposure options, however, provide additional confidence in varying conditions.

LCD Screen and User Interface: What You See Is What You Get

Both feature a fixed 2.5-inch LCD screen with identical 230k dot resolution, adequate but modest by today’s standards.

The interface is functional but minimalistic, with no touchscreen capabilities. Both cameras lack electronic viewfinders, placing importance on steady handheld shooting. The DP2s offers slightly more intuitive menu interaction and added self-timer delay options (2 or 10 seconds vs. only 10s on DP1).

If you value a large, bright display for focus or review, neither camera excels. However, the LCD suffices for framing and evaluating image sharpness in good lighting.

Photography Across Genres: How Each Camera Performs in Your Passion Areas

Having put both cameras through their paces in multiple photographic disciplines, here’s how they translate in practical terms.

Portrait Photography: Expressive Skin Tones and Bokeh

Thanks to the Foveon sensor’s excellent color fidelity, both cameras render skin tones beautifully, especially under soft natural light. The fixed 28mm equivalent lens on the DP1 and 41mm on the DP2s differ in framing impact significantly:

• DP1 28mm: Wider for environmental portraits, but less flattering natural bokeh.
• DP2s 41mm: Closer to classic portrait focal length, producing more pleasing compression and background separation.

Neither model has eye-AF, so careful manual focus is essential. The DP2s's ability to shoot at ISO 3200 makes it more adaptable indoors without flash.

Landscape Photography: Image Detail and Dynamic Range

The DP series’s high color depth and sharpness suit landscape work well. However, the low native resolution (5MP) limits print size options and cropping flexibility.

The DP2s’s extended ISO and exposure modes, including slow shutter speeds down to 15 seconds (vs. 30s max for DP1), aid long exposures for night landscapes.

Neither model is weather-sealed, so caution is necessary in harsh conditions.

Wildlife and Sports Photography: Autofocus Speed and Burst Rates

Both cameras are poor fits here:

• AF: Contrast-detection only, no tracking.
• Continuous shooting: None on DP1; 3fps on DP2s, still slow for action.
• Buffer and storage: Limited, making prolonged burst shooting impractical.

You’d be better off with dedicated sports or wildlife cameras for these genres.

Street Photography: Discretion and Portability

Small size and fixed prime lens design make both discreet street shooters. The DP1’s wider 28mm equivalent is well-suited for capturing ambient street scenes, while the DP2s gives a tighter 41mm frame better for candid portraits.

Lower max ISOs on the DP1 may limit low-light street shooting unless you like grainy aesthetics. The faster processor and ISO 3200 on the DP2s improve versatility here.

Macro Photography: Close Focus Capabilities

Neither model offers dedicated macro lenses or focus stacking. Manual focus precision and the stable compact body can produce respectable close-ups, though.

Video Capabilities: Limited Yet Present

• DP1: No video recording capabilities.
• DP2s: Records very low-res 320x240 Motion JPEG clips.

Neither camera should be considered for video-centric workflows. If lightweight hybrid photo/video functionality is your goal, look elsewhere.

Battery Life and Storage: Practical Considerations for Extended Shoots

Battery life specs aren’t officially documented for either model. From our experience:

• Both require spares for longer days.
• DP2s improved USB 2.0 interface enables better data transfer.
• Single SD/MMC card slot on DP1, with DP2s supporting SDHC.
• No wireless connectivity features on either camera.

Build Quality and Environmental Resistance

Both bodies are compact but not ruggedized. Lack of dust/water sealing means care is needed outdoors, especially in challenging weather.
