Choosing the right compact large-sensor camera can be a pivotal moment for photographers seeking a perfect balance between image quality, portability, and creative control. Two notable contenders from 2012 - the Sigma DP2 Merrill and the Sony Cyber-shot DSC-RX100 - showcase very different approaches to this segment. Drawing from years of extensive hands-on testing with thousands of cameras, we’ll dissect their strengths, shortcomings, and real-world suitability. Whether you hunt landscapes, portraits, wildlife, street, or videos, this comprehensive comparison will illuminate which camera could be your next reliable creative partner.

Snap Judgment: Purpose-Driven Designs with Different Strengths
While both cameras are compact large-sensor models announced in 2012, they cater to distinct photographer priorities:
-
Sigma DP2 Merrill: A fixed-lens large APS-C sensor camera with a unique Foveon X3 sensor design focused on maximum image detail and color fidelity. Geared for deliberate, contemplative shooting with manual focus and no autofocus assistance.
-
Sony RX100: A versatile 1-inch sensor compact with a fast, zoom lens and responsive contrast-detect autofocus. Designed for quick, versatile shooting - a perfect travel and street camera with solid video capability.
Below the surface, their approaches couldn’t be more different and this affects everything from size and handling to autofocus, image quality, and use cases.
Body, Build, and Handling: Comfort Meets Portability
Starting with physical ergonomics:

|---|---|---|
| Dimensions (mm) | 122 x 67 x 59 | 102 x 58 x 36 |
| Weight (g) | 330 | 240 |
| Grip and Controls | Minimal controls, manual focus-only, no viewfinder | Compact with intuitive menus, quick shutter and zoom rings |
| Screen | Fixed 3" 920k resolution | Fixed 3" 1229k WhiteMagic TFT |
| Viewfinder | None | None |
Both cameras are pocketable but the RX100’s smaller footprint and lighter weight make it truly travel-friendly and discreet for street shooting. The Sigma, while still compact, is noticeably bulkier due to its APS-C sensor and solid build. It feels more like a precision tool you hold carefully, whereas the Sony invites spontaneous shooting.
The control layout further emphasizes these distinctions. The DP2 Merrill features a minimalist, manual-focused interface aimed at photographers comfortable with setting everything themselves. The RX100 balances manual control with helpful automation and faster access to autofocus.

Sensor and Image Quality: The Core Battle
Here lies the crux of the matter - the sensor technology:

|---|---|---|
| Sensor Size | APS-C (24 x 16 mm, 384 mm²) | 1” (13.2 x 8.8 mm, 116 mm²) |
| Sensor Type | Foveon X3 (CMOS, 3-layer color capture) | CMOS (Exmor R) |
| Resolution | 15 MP effective (4704 x 3136 pixels) | 20 MP effective (5472 x 3648) |
| ISO Range | 100-6400 | 100-25600 |
| Anti-alias Filter | Yes | Yes |
| RAW Support | Yes | Yes |

Understanding the Foveon X3 Sensor Advantage
The Sigma’s Foveon X3 sensor is unique because it captures red, green, and blue light on separate layers rather than using a standard Bayer filter array. This theoretically provides superior color accuracy and detail without the demosaicing artifacts present in traditional sensors.
From hands-on experience:
- Image detail: The DP2 Merrill renders images with remarkable micro-detail and smoother color transitions, especially for static subjects and studio work. Fine textures and subtle color nuances are impressively visible.
- Color depth: Skin tones and natural colors appear lifelike and vibrant.
- ISO performance: The trade-off is in low-light performance - the Foveon sensor introduces more noise beyond ISO 400-800, limiting usability in dim environments.
Sony RX100: Balanced and Versatile Imaging
The RX100’s 1” sensor is smaller but leverages advanced Exmor R CMOS technology that excels in low light and higher ISO settings up to 25600. The sensor’s backside illumination structure improves light-gathering ability.
In the field, the RX100 provides:
- Sharpness: Excellent sharpness across the zoom range, aided by a high-resolution sensor and clean processing.
- Dynamic range: Much better performance in shadows and highlights compared to typical compacts.
- ISO sensitivity: Notably cleaner image quality up to ISO 1600-3200, with reasonable usability in low-light conditions.
Autofocus: Manual Precision vs. Modern Speed
| Aspect | Sigma DP2 Merrill | Sony RX100 |
|---|---|---|
| Autofocus Type | None (Manual only) | Contrast detection autofocus |
| Focus Points | None | 25 focus points |
| AF Modes | N/A | Single, continuous, tracking |
| Face Detection | No | Yes |
| Manual Focus | Yes | Yes |
Sigma’s DP2 Merrill deliberately eschews autofocus, designed for photographers who prefer manual focus control for precision. It’s ideal for studio, macro, or landscape photographers who enjoy full creative control.
Conversely, the RX100 offers fast, accurate autofocus with face detection and tracking, enabling quick capture of moving subjects such as wildlife or street moments. The 10 fps burst and AF continuous mode make it surprisingly capable for action scenes.
