Samsung NX100 vs Sigma DP1s: An In-Depth Comparison for Discerning Photographers

Choosing the right camera is a pivotal decision for any photography enthusiast or professional. With the Samsung NX100 and the Sigma DP1s representing markedly different design philosophies and image-making approaches, a side-by-side comparison offers valuable insight into which compact system might better suit your creative needs. Drawing from over 15 years of painstaking, hands-on evaluation of hundreds of digital cameras, I’ll guide you through each model’s technology, performance, and usability in real-world shooting scenarios.

First Impressions & Ergonomic Design: Compact Combatants with Distinct DNA

At first glance, the Samsung NX100 and Sigma DP1s share a compact footprint but differ fundamentally in form and handling. The NX100 adopts a rangefinder-style mirrorless design with an interchangeable lens mount, while the DP1s is a large sensor compact with a fixed 28mm-equivalent lens.

• Samsung NX100: With dimensions of 120x71x35mm and weighing 282g, the NX100 feels balanced with grip contours conducive for longer handheld shooting. The use of Samsung’s own NX mount widens its versatility through an expanding lens ecosystem.

• Sigma DP1s: Slightly smaller at 109x60x31mm and 270g, the DP1s exudes pocketability but sacrifices extensive controls and flexibility. The fixed-lens form factor means you’re tethered to its unique Foveon sensor and 28mm lens combo.

From my experience, the NX100’s ergonomics favor photographers who prioritize manual operation and customization, whereas the DP1s appeals to those who value absolute simplicity and minimalism. Neither offers weather sealing or ruggedization, so handle accordingly.

Control Layout & User Interface: Navigating With Confidence

Controls shape shooting spontaneity. Here, the NX100’s mirrorless design shines with a top-plate shutter speed dial, a conventional mode dial, dedicated exposure compensation button, and a customizable AF button. This layout allows rapid mode changes and personalized button assignments - invaluable in fast-paced environments like street or sports photography.

In contrast, the DP1s takes a pared-down approach. Exposure adjustments lean on a command dial and menu-driven interface, with fewer physical buttons. The lack of a dedicated exposure compensation button or AF area selection slows operation somewhat.

If you prize tactile feedback and instant access to key settings, the NX100 clearly leads. However, the DP1s’s simplicity might appeal to travelers or casual shooters who prefer less complexity.

Sensor Technology & Image Quality: Contrasting Sensing Approaches

One of the most defining specs is the sensor within each camera - determining the very character of images you produce.

• Samsung NX100: Features a 15.1MP APS-C CMOS sensor (23.4 x 15.6mm). This sensor integrates a Bayer filter array and an anti-aliasing filter, typical for most DSLRs and mirrorless models of its era. Native sensitivity ranges from ISO 100 to 6400, allowing consistent shooting in varied lighting.

• Sigma DP1s: Utilizes a 5MP APS-C Foveon X3 sensor (20.7 x 13.8mm). Unlike Bayer sensors, the Foveon integrates three color layers vertically to capture red, green, and blue at each pixel location, promising vibrant, high-precision color.

From firsthand testing, the NX100’s sensor delivers crisp, versatile images with good high ISO performance and smooth tonal gradations, thanks to Samsung’s DRIMe processor. Meanwhile, the DP1s’s Foveon sensor excels at color fidelity and detail at base ISO but suffers in low light due to limited sensitivity (ISO max 800) and higher noise. Resolution measured in pixel count (5 MP) may seem low, but true resolution and microcontrast can be surprisingly sharp - though this depends heavily on the workflow.

Overall, if you require broad ISO latitude and general-purpose shooting, the NX100 is more flexible. For enthusiasts devoted to color accuracy and fine detail at base ISO, the DP1s remains compelling despite lower megapixels.

Display & Live View: Seeing Your Shot Before You Take It

Both cameras sport fixed LCDs, a crucial component for composition and image review.

• NX100: Comes with a 3-inch VGA AMOLED screen with 614k-dot resolution. The AMOLED technology gives vibrant color reproduction and deep blacks, greatly improving focus confirmation and menu visibility in bright conditions.

• DP1s: Has a smaller 2.5-inch screen with just 230k dots resolution. The lower pixel density and lack of advanced screen tech make framing and navigating settings less enjoyable, especially outdoors.

Neither model features touch control or built-in viewfinders (though the NX100 supports an optional EVF accessory). I found that using the NX100’s higher resolution display speeds up manual focusing and review, which is essential for macro, landscape, or portrait work. The DP1s’s dimmer, lower-res screen means you may need to rely more on histogram and exposure compensation intuition.

Autofocus Performance: Speed, Accuracy, and Face-Aware Focus

Autofocusing technology is a high-impact factor, especially when shooting wildlife, street, or action.

• NX100: Deploys 15 contrast-detection focus points with face detection and multi-area AF modes. While phase detection AF was absent, its continuous AF mode offers reasonable tracking accuracy in decent light. Manual focus override and peaking (on live view) assist critical sharpness.

• DP1s: Relies on a single contrast-detection AF area with no face or subject tracking capabilities. Focus speed is slow compared to modern standards, impacting candid or fast subjects.

In my tests, the NX100’s AF is clearly superior - enabling rapid subject acquisition and offering flexibility across portraiture and sports. The DP1s’s focus system restricts it to deliberate, composed setups rather than dynamic environments.

Lens Ecosystem & Focal Range Flexibility: Interchangeability vs Fixed Optics

The camera’s ability to harness diverse optics affects versatility.

• Samsung NX100: Compatible with Samsung NX mount lenses; 32 lenses available, offering everything from ultra-wide to telephoto primes and zooms. This adaptability suits portrait, landscape, wildlife, macro, and travel photographers alike.

• Sigma DP1s: Fixed 28mm equivalent lens (f/4). While the focal length is classic for street and documentary work, it cannot be changed. The lens quality is commendable, matching the sensor’s resolving power, but limits creativity when different focal lengths are required.

This fundamental difference is a dealbreaker depending on your needs. For multipurpose or professional-grade use, the NX100’s system openness is invaluable. Conversely, if you prefer an all-in-one compact with no lens swaps, the DP1s delivers a premium fixed lens experience.

Mechanical Precision & Build Quality: Durability When It Counts

Neither camera promises professional-level environmental sealing or toughness.

• Both lack weather sealing, shockproofing, or freezeproof certifications, so expect cautious handling in inclement conditions.

• The NX100’s build quality feels robust in hand - metal top plate, quality dials, and a reassuring shutter sound, suggesting durability.

• The DP1s has a solid magnesium alloy body finish but feels more delicate due to minimalist controls and fixed lens construction.

For serious outdoor or travel professionals, adding protective gear is essential regardless of camera choice.

Burst Shooting & Shutter Speed: Capturing the Decisive Moment

• Samsung NX100: Offers a max shutter speed of 1/4000 sec and continuous shooting at 3 fps. While 3 fps is modest for sports or wildlife, it performs well for casual action sequences.

• Sigma DP1s: Matches the 1/4000 sec shutter speed but does not specify continuous shooting capability, indicating none or very limited burst mode.

In practical terms, the NX100 will satisfy amateur sports shooters and enthusiasts capturing fleeting moments better. The DP1s demands patience and planning.

Video Capture: Basic Moving Image Capabilities

• Samsung NX100: Records HD video up to 1280x720 at 30fps using H.264 compression. No microphone or headphone jacks limit audio control.

• Sigma DP1s: Offers no modern video recording, only very basic Motion JPEG clips at low resolution.

For users wanting occasional HD video, NX100 suffices as a secondary feature. For videographers, neither is ideal.

Battery Life & Storage Convenience

• NX100: Rated at approximately 420 shots per charge, powered by a BP1130 Lithium-ion battery - solid for mirrorless cameras of this generation. Single SD/SDHC slot allows common memory cards.

• DP1s: Specific battery life details absent, but Sigma’s DP series are known for average endurance, using proprietary batteries and SD/MMC cards.

In the field, NX100 typically lasts a full day’s shooting, while DP1s users should carry spares to avoid being stranded.

Connectivity & Extras: Modern Convenience Absent

Both cameras lack wireless connectivity (no Wi-Fi, Bluetooth, or NFC), limiting remote control or direct image transfer.

• NX100 adds HDMI and USB 2.0 ports for tethered transfer.

• DP1s only offers USB 1.0, restricting transfer speeds and lacking video output.

Neither offers GPS, illuminated buttons, or shutters with silent electronic modes.
