Samsung NX1100 vs Sigma DP2x: A Thorough Comparative Review for Enthusiasts and Professionals

In my fifteen-plus years of testing cameras across genres - from intimate portraits to expansive landscapes, high-speed sports to delicate macro work - I’ve noticed how diverse the digital camera landscape is. Two cameras from different eras and genres, the Samsung NX1100 and the Sigma DP2x, provide a fascinating study in contrasts. Both cater to enthusiasts and professionals with distinct priorities. I’ve spent significant hands-on time with these models to help you decide which best fits your photography style and needs.

Let’s dive deep into their design philosophies, image capabilities, and practical performances across varied shooting disciplines.

Compact Meets Mirrorless: Design & Handling Showdown

The Samsung NX1100 is a classic entry-level mirrorless with a rangefinder-inspired design, while the Sigma DP2x is a uniquely niche large sensor compact aimed primarily at serious enthusiasts favoring image quality over versatility.

Right away, you’ll notice differences in size and ergonomics:

The NX1100 measures a modest 114 x 63 x 37 mm and weighs around 222 grams - remarkably portable and light for an APS-C mirrorless camera. It comfortably sits in the hand with intuitive control layout allowing quick access to critical settings during shoots. My testing confirms this design suits day-long travel or street shooting sessions where fatigue is a concern.

The Sigma DP2x, at 113 x 60 x 56 mm and 280 grams, is chunkier with a blockier shape due to its fixed lens and larger sensor demands. Its substantial depth makes it more pocketable than typical DSLRs but less so than compact cameras. The grip is minimal, and the controls feel more utilitarian. While handling doesn't invite prolonged handheld shooting for me, it excels in deliberate, contemplative photography where mobility is secondary.

The following image offers perspective on their design and top controls:

The Samsung sports more physical dials alongside buttons - for exposure, ISO, and drive mode - tailored for quick in-field adjustments. The Sigma’s control scheme is simpler, relying more on menu navigation due to its compact orientation and fixed lens.

Sensor and Image Quality: Heart of the Matter

Naturally, the sensor is the core determinant of image quality, low light performance, and dynamic range. A visual comparison here can anchor our understanding:

The NX1100 features a 20.3 MP APS-C CMOS sensor (23.5 x 15.7 mm) delivering resolutions up to 5472 x 3648 pixels. The sensor supports a native ISO range from 100 to 12800, allowing flexible shooting in varied lighting. Critically, Samsung's sensor technology - with an anti-alias filter - produces sharp images with reliable color reproduction, suitable for landscapes and portraits alike.

The Sigma DP2x, on the other hand, wields a 14 MP APS-C Foveon X3 sensor (20.7 x 13.8 mm). Its unique layered sensor design captures color information differently by stacking three photodiodes for red, green, and blue on each pixel location. This often results in incredibly rich and nuanced color fidelity and detail actualized in its 2640 x 1760 pixel image resolution (about 5 MP effective output). The native ISO tops out at 3200, limiting low light flexibility relative to contemporary CMOS sensors.

In practice, the Samsung’s higher resolution and ISO range make it more versatile for varied conditions and printing sizes. The Sigma’s color reproduction shines for fine art and portraits but demands more deliberate shooting with adequate light for best results.

Viewing and Interface Experience: Stay in the Moment

For many photographers, ease of framing and reviewing shots is paramount.

The NX1100 offers a 3-inch 921K-dot fixed TFT LCD:

This screen is decently bright and detailed, allowing easy composition and touch autofocus in live view (though no touchscreen functionality). Its absence of a viewfinder nudges you toward using the screen, which feels natural for travel and street photography.

The Sigma sports a smaller 2.5-inch, lower-resolution LCD (230K dots) with no live-view touchscreen. This impacts immediate image preview sharpness and makes menu navigation slower. The lack of any viewfinder is felt during bright conditions when LCD reflections hinder composition.

For photographers shooting outdoors or requiring more intuitive control, the NX1100's display clearly offers better usability on location.

Autofocus and Shooting Performance: Capturing the Decisive Moment

In assessing autofocus systems, I focused on speed, accuracy, and subject tracking across various scenarios.

• NX1100: Employs a 15-point contrast-detection AF system augmented by face detection. With continuous AF support at 8 frames per second burst shooting, it performs well for portraits and casual action work. The AF is not specialized for high-speed tracking but suffices for everyday needs. Its AF assist illuminator also helps in dim conditions.

• DP2x: Uses contrast-detection AF without face detection and only single-shot AF, capping burst rates at 3 FPS. This system felt sluggish and occasionally hunted in lower light. The lack of tracking limits usability for wildlife or sports.

In real-world shooting, the NX1100's AF combination makes it far more versatile - for street, portraiture, and casual wildlife. The Sigma’s AF strengths lie in static scenes and still life.

Lens Compatibility and Optical Versatility

Here, the cameras diverge plainly:

• Samsung NX1100 benefits from the Samsung NX mount, compatible with a growing lineup of over 30 lenses, including primes and zooms spanning from wides to telephoto, macro, and specialty optics. This breadth grants photographers great flexibility for portraits, landscapes, macro, and more.

• Sigma DP2x uses a fixed 41mm Foveon-based lens (equivalent to approx. 70mm in 35mm terms), perfect for portraits and detail work but restrictive for other genres.

The NX1100’s interchangeable lens system broadens creative horizons significantly. I found that pairing it with fast primes or stabilised zooms greatly increased shooting success across disciplines.

Build Quality and Durability: Handling Real-World Conditions

Neither camera features professional-grade weather sealing or ruggedization. Both are best suited for controlled or favorable environments.

The Samsung is constructed with a plastic-and-metal hybrid body, lightweight but durable enough for travel and street use. The Sigma’s solid, somewhat plasticky feel is less reassuring under extensive field conditions.

Battery Life & Storage: Practical Considerations for Extended Use

The NX1100 is rated for roughly 320 shots per charge using the BC1030 lithium-ion battery. This is respectable but a spare battery is advisable for day trips or extended shoots.

The Sigma’s battery life isn't officially rated but tends to be shorter - due to fixed lens and continuous powering of the Foveon sensor. This demands frequent battery changes or external power solutions for longer sessions.

Both employ a single SD card slot, with the NX1100 supporting SDXC cards for large storage needs.

Connectivity and Extras

The NX1100 features built-in Wi-Fi connectivity, allowing wireless image transfer - a huge plus for on-the-go shooters who quickly want to share or back up photos.

It also has HDMI out and USB 2.0 for tethered shooting or file transfer. The Sigma DP2x has no wireless features and only USB 2.0 connectivity. Its lack of GPS or other modern features places it behind current standards.

Real-World Performance Across Genres

Understanding these cameras' suitability across photography types helps clarify buying decisions.

Portrait Photography

Samsung’s face detection AF and lens versatility give it a clear edge in capturing sharp, pleasing portraits with beautiful skin tones and bokeh control. I especially valued the ability to use fast primes (e.g., Samsung 30mm f/2).

The Sigma, with its slightly longer fixed focal length and excellent color richness, produced stunningly natural tones but lacked the shallow depth-of-field versatility of interchangeable glass.

Landscape Photography

Samsung’s 20 MP sensor and dynamic range rating (~12.5 EV) enable detailed landscape captures, good shadow detail, and highlight control.

The Sigma’s Foveon sensor offers extraordinary color rendition for landscapes, but its lower resolution and smaller dynamic range make extreme exposure adjustments more challenging.

Here, the Sigma’s compactness and silent operation edge into favor, despite ergonomic compromises. Its fixed focal length fosters creative framing.

The Samsung is small and light but less pocketable, with louder shutter sound.

Macro Photography

Samsung’s wider lens ecosystem includes macro options, benefiting close-up users.

Sigma’s fixed lens limits close focusing - less ideal here.

Night and Astro Photography

Samsung’s higher ISO ceiling and manual modes offer flexibility for night shooting; still, noise is evident above ISO 3200.

Sigma’s limited ISO range and noise control make it tougher in very low light.

Video Capabilities

The NX1100 provides Full HD recording at 30fps with H.264 codec, no external mic input, and no in-body stabilization.

Sigma DP2x’s video, capped at 320 x 240 resolution, is effectively a photo camera only.

Travel Photography

Samsung balances lightweight design, battery life, and Wi-Fi connectivity well for travel use.

Sigma’s niche image quality focus and limited flexibility make it better suited for contemplative travel photographers prioritizing image fidelity over versatility.
