First Impressions: Handling and Design

Coming out of the box, these two cameras immediately contrast in ergonomics and form factor.

Sigma DP2 Merrill

The DP2 Merrill feels chunky and solid in the hand, thanks largely to its fixed 50mm F2.8 lens and the larger APS-C sensor inside. Its dimensions of 122x67x59 mm and weight of 330g give it a substantial feel compared to typical compacts. The textured body offers a comfortable grip, but its rigidity and heft make it less grab-and-go than the RX100 II.

Notably, the DP2 Merrill opts for a minimalist control layout - no autofocus assistance, no stabilization, and a fixed screen - focusing instead on pure image quality. It is in some ways more of a digital “rangefinder-style” device than a traditional compact.

Sony RX100 II

On the other hand, the RX100 II is a sleek pocket-sized powerhouse, measuring 102x58x38 mm and weighing just 281g. Its compactness truly live up to the “travel-friendly” moniker. The tilting 3-inch screen with a high 1229k-dot resolution feels refined, and the inclusion of manual dials, a built-in flash, and optional electronic viewfinder shows Sony’s commitment to balancing compactness with flexible handling.

Whether street shooting or traveling light, the RX100 II demands less commitment in terms of bulk and handling strain.

Sensor Tech and Image Quality Breakdown

At the heart of a large sensor compact camera is the sensor itself. Here, the DP2 Merrill and the RX100 II differ fundamentally.

Sigma DP2 Merrill: The Unique Foveon X3 Sensor

Sigma’s DP2 Merrill boasts a 15 MP APS-C Foveon X3 sensor - a departure from traditional Bayer sensors. Instead of filtering colors through a mosaic, the Foveon uses three layers of photodiodes to capture red, green, and blue at every pixel location. This results in superb color fidelity, incredibly sharp images particularly at base ISO, and notably organic skin tones.

However, the sensor size at 24x16 mm gives it an advantage in dynamic range but introduces challenges in low light and noise levels. Another trade-off is with resolution: although the file is 15 MP, the top-line resolution aligns uniquely with the layered sensor design rather than pure pixel count metrics.

The sensor pairs with Sigma’s Dual TRUE II engine processor - optimized for high detail extraction, but lacking modern noise reduction features you’ll find on contemporary CMOS sensors.

Sony RX100 II: Classic 1-Inch Exmor CMOS

The RX100 II sports a 20 MP 1-inch CMOS sensor (13.2x8.8 mm), smaller than Sigma’s APS-C but notable for resolution and speed. Sony uses a classic Bayer filter array sensor, delivering excellent detail and expanded usability at higher ISO settings.

With a peak native ISO of 12800, plus ISO boost to 25600 (though noise becomes more apparent at those levels), the RX100 II excels in low-light shooting - something the DP2 Merrill struggles with. Its sensor also supports faster readout, quick autofocus, and video capturing, features enhanced by Sony’s BIONZ image processor.

Let’s ground this with a visual comparison of sensor sizes and implications for image quality:

My Testing Experience

Shooting side-by-side in daylight landscapes and controlled portraits, I observed:

• DP2 Merrill excels in color depth and detail resolution at base ISO 100–200, with luscious skin tones and excellent lens sharpness.
• RX100 II performs better under low-light conditions, delivering cleaner images at ISO 800 and above, with boosted flexibility.

More on this in the photography use case sections.

Viewing and Interface: How You See Your Photos Matters

Especially with fixed-lens cameras, interface design impacts your creative flow significantly.

Sigma DP2 Merrill

With a fixed, non-touch 3-inch LCD at 920k dots, the DP2’s display gets the job done but feels dated by modern standards. You won’t find a viewfinder - electronic or optical - so composing shots can require flexibility. The camera employs no touchscreen interface, and menu navigation is a bit clunky, requiring some patience.

Sony RX100 II

In contrast, the RX100 II features a tilting 3-inch Xtra Fine WhiteMagic TFT LCD with 1229k-dot resolution - usable even under bright sunlight. Though not a touchscreen, its interface is responsive with easy manual control dials and a straightforward menu system.

Additional points include the optional pop-up electronic viewfinder (sold separately on some packages), which assists in bright outdoor framing and stabilizing your grip.

Autofocus and Performance: Speed and Precision in the Moment

This is a critical real-world factor, especially for dynamic photography genres.

Sigma DP2 Merrill

Being primarily built for image quality, the DP2 Merrill lacks any autofocus system - it's fully manual focus only. This means you must rely on zone focusing or precise manual adjustment, hardly ideal for spontaneous or fast-moving scenarios. The absence of face detection, autofocus points, or tracking capabilities limits usability for wildlife, sports, or street photography where speed is essential.

The result is: photographer skill and patience take center stage here.

Sony RX100 II

The RX100 II adopts a contrast-detection AF system with 25 focus points and face detection. Though not phase detection, the autofocus is quick and accurate across a wide range of situations. It supports continuous autofocus, focus tracking, and selective AF modes, improving success rates in dynamic environments.

With a burst rate of 10 fps, the RX100 II is practical for sports and wildlife shooting on a compact scale.

Lens and Zoom Versatility: Fixed Prime vs Zoom Flexibility

Lens choice often defines your shooting versatility and style.

Sigma DP2 Merrill’s Fixed 50mm F2.8 Lens

This classic prime lens equates to about 75mm in full-frame terms, excellent for portraits, still life, and controlled compositions. The F2.8 aperture facilitates shallow depth of field and decent low-light capability but lacks image stabilization.

The fixed prime lens reinforces the camera’s intention for deliberate, detail-oriented photography, often favoring studio and portrait environments.

Sony RX100 II’s 28-100mm F1.8-4.9 Zoom

The RX100 II’s zoom lens spans wide-angle to short telephoto (28–100mm full-frame equivalent), offering much more framing flexibility on the go. Its fastest aperture of F1.8 at the wide end enables solid low-light shooting, gradually narrowing to F4.9 at full zoom.

Additionally, the RX100 II has built-in optical image stabilization (OIS) - a significant aid when shooting handheld at longer zooms or in dim light.

Pros and Cons on Lenses

• DP2 Merrill: Superior optical performance at fixed focal length; sharper, less optical distortion but limited framing.
• RX100 II: Versatile focal range is user-friendly; built-in stabilization expands handheld usability.

Real-World Photography for Different Genres

Let’s unpack which camera serves distinct styles best, based on my extensive field testing.
