Samsung PL170 vs Sigma DP1 Merrill: An Expert Comparison for Photography Enthusiasts

Choosing the right camera can be a daunting task given the vast diversity in sensor sizes, features, and intended uses. Today, we delve into a direct comparison between two compact cameras that, on paper, cater to very different user needs: the Samsung PL170, an approachable ultracompact pocket camera, and the Sigma DP1 Merrill, a more specialized large sensor compact aimed at image quality purists.

Having spent over 15 years testing and field-evaluating cameras across all genres - from candid street shots to commercial portraiture - this analysis will take you beyond mere specs. I’ll share first-hand insights, detailed technical breakdowns, and practical recommendations to help you identify which of these cameras fits your photography style and budget.

A Tale of Two Designs: Size and Ergonomics

At first glance, the Samsung PL170 and Sigma DP1 Merrill couldn’t be more different in form factor. The Samsung PL170 is a true ultracompact, pocketable camera measuring a slender 95 x 57 x 19 millimeters. This slimness makes it exceptionally portable for casual or travel photographers who prioritize convenience and ease of carry.

In contrast, the Sigma DP1 Merrill stands out with its substantial 122 x 67 x 64 mm body, tipping the scales at about 330 grams. Its chunky build reflects the large sensor seated inside, and it resembles a bridge-style camera more than a typical simple compact. While not bulky by DSLR standards, it’s a noticeable step up in heft and size compared to the PL170.

Ergonomically, the PL170 uses a minimal layout with straightforward button placement suited for casual users. In contrast, the DP1 Merrill’s physical bulk allows more precise manual controls and a better grip for deliberate shooting sessions. The DP1 Merrill requires some getting used to in handling due to its boxy design, but the payoff is in its control options.

Looking from above, the PL170’s control scheme is kept simple - minimal dials and no external manual focus. You mainly rely on basic automatic shooting modes, which means faster setup but less creative control. The DP1 Merrill, meanwhile, offers manual exposure modes, shutter priority, aperture priority, and supports classic DSLR-style shooting approaches - even though it lacks an optical or electronic viewfinder, relying exclusively on its LCD for composition.

If you value quick snapshots and pocket portability, the PL170’s design will appeal. If you prefer a more deliberate, hands-on shooting experience, the DP1 Merrill’s ergonomics are a more versatile match.

Sensor Technology and Image Quality: The Core Difference

The heart of any camera is its sensor, and here the chasm between these two models is vast.

• Samsung PL170 uses a 1/2.3-inch CCD sensor (6.08 x 4.56 mm) with a 16-megapixel resolution. CCD sensors were common in ultracompacts of its era and are known for decent color fidelity but limited dynamic range and high noise at elevated ISOs.
• Sigma DP1 Merrill houses an APS-C sized CMOS Foveon X3 sensor (24 x 16 mm) with a 15-megapixel effective resolution; with the Foveon’s unique layered sensor design, it captures full color information at each pixel location, promising exceptional color accuracy and sharpness.

In practice, the PL170’s small sensor offers reasonable detail and color under good lighting but struggles in low light due to its limited ISO range (up to ISO 3200 native) and lacks the refined tonal gradation of larger sensors.

The DP1 Merrill’s sensor produces stunning images with remarkable detail and natural colors thanks to the Foveon architecture. Be warned, though: while its ISO tops at 6400, noise performance declines above 800 ISO noticeably. Additionally, image processing can be slower, and the unique RAW files require specialized software. This camera targets photographers who prioritize image quality over speed and convenience.

• The PL170 produces bright, punchy JPEGs suitable for casual prints or social sharing. However, look closely, and you’ll find softness in fine textures and limited shadow detail.
• The DP1 Merrill captures landscape scenes with rich, nuanced colors and excellent sharpness, retaining subtle tonal shifts in shadows and highlights that the PL170 misses.

Portraits taken with the DP1 Merrill exhibit superior skin tone rendition and graceful bokeh from its wider lens aperture (f/2.8), while the PL170’s fixed smaller lens aperture yields flat backgrounds and less three-dimensional subject separation.

LCD and Interface: How You Interact Matters

The PL170 features a 3-inch fixed LCD with 230k pixel resolution. The screen is clear in shaded areas but struggles in bright sunlight; its low resolution makes precise manual focus or composition adjustments difficult.

The DP1 Merrill’s LCD has a zoomed-in higher resolution of 920k pixels (though smaller physically), which aids framing and reviewing images accurately. However, neither camera sports a touchscreen or electronic viewfinder, which might frustrate users accustomed to modern interfaces.

The DP1 Merrill’s menus offer comprehensive exposure control, white balance customization, and manual focusing aids - essential for hard-core enthusiasts who like to craft each shot. The PL170 keeps things simple, catering more to point-and-shoot convenience.
