Samsung NX100 vs Sigma fp L: An In-Depth Comparison for the Pragmatic Photographer

Choosing a camera is a lot like choosing a companion for your photographic journey - it needs to fit your style, adapt to your environments, and sometimes surprise you with capabilities you didn’t expect. Today, I’m diving into a head-to-head comparison of two mirrorless cameras from very different eras and design philosophies: the Samsung NX100, an entry-level model launched in 2010, and the Sigma fp L, a cutting-edge advanced mirrorless camera from 2021.

Although they are separated by more than a decade - and a world of technology advancement - comparing these two can still yield surprising insights about how camera technology matured and what really matters for photographers across genres.

Let’s buckle up and explore sensor technology, build quality, handling, image quality, autofocus, video, and usability. Plus, I’ll share real-world impressions after countless hours testing both for portraits, landscapes, wildlife, street photography, and more.

Size, Handling, and Ergonomics: The Feel of the Machine

When I first picked up the Samsung NX100, its compact, rangefinder-style body was unmistakably lightweight and friendly for newcomers craving portability. The Sigma fp L, in contrast, feels like a statement - minimalistic but undeniably robust and geared toward pros who want uncompromising control.

Putting them side-by-side really highlights the evolution of ergonomics and design priorities.

The NX100 weighs a mere 282 grams and measures 120x71x35mm. It slips comfortably into smaller bags, making it an attractive travel companion or street shooter’s delight. But the slim body also means shallower grips and fewer dedicated controls, which might feel limiting once you step beyond beginner territory.

The Sigma fp L, at 427 grams and 113x70x45mm, is chunkier but still remarkably compact for a full-frame powerhouse. It favors a slab-style design - streamlined with minimal protrusions. The deeper grip improves handling with heavier lenses, but its utilitarian styling might intimidate casual shooters who expect neat button layouts.

Control-wise, NX100 keeps it simple - shutter speed and aperture priority modes, exposure compensation, and a single customizable dial. In contrast, the fp L offers a wider array of customizable buttons, with illuminated feedback and a touch-capable rear screen (more on that later). It’s built with the expectation that users want granular control over camera settings without diving into endless menu pits.

In short: if you prize portability and straightforward operation, the NX100’s ergonomics will charm you. But if you want a camera designed to be molded around your shooting style - especially with advanced manual controls - the fp L clearly leads the pack.

Sensor Specs and Image Quality: From APS-C to Full Frame Brilliance

Never underestimate how much the sensor defines your image quality. When testing, I use standardized charts and the real-world shooting of challenging subjects - portraits with nuanced skin tones, landscapes with tricky lighting, and high-contrast scenes - to evaluate resolution, dynamic range, color depth, and noise handling.

The Samsung NX100 packs a 15.0-megapixel APS-C CMOS sensor (23.4 x 15.6 mm). It felt standard for 2010, with reasonable noise performance up to ISO 1600 and decent dynamic range for the era. However, its 10.7 EV dynamic range and color depth around 22.6 bits are now modest by comparison. That anti-alias filter slightly blurs fine details, which impacts landscapes and macro shots wanting crisp textures.

On the flip side, the Sigma fp L sports an astounding 61.0-megapixel full-frame BSI-CMOS sensor (36 x 24 mm), leveraging backside illumination for improved light gathering. The pixel count nearly quadruples the NX100’s, delivering amazing detail - think ultimate cropping ability and large print potential.

While DxOMark hasn’t tested the fp L specifically, Sigma’s sensor lineage (shared with specialized medium format influence) achieves excellent color rendition, wide dynamic range, and surprisingly good noise control even pushed near ISO 25600.

For portraits, the fp L’s full-frame sensor renders skin tones with rich gradation and natural hues that make retouching a breeze. Landscapes benefit from nuts-and-bolts dynamic range capturing shadow and highlight information exquisitely. Meanwhile, the NX100 can produce nice images but clearly shows its limitations in noisy shadows and blown highlights.

LCD Screens & Viewfinders: Interfaces and User Experience

An often overlooked but crucial area is how the camera communicates feedback and allows adjustments in the field. I take many photos in unpredictable lighting - bright sun, dim interiors, moving subjects - so screen clarity, responsiveness, and viewfinder quality can greatly affect my shooting efficiency.

The NX100’s 3-inch fixed AMOLED screen, with 614k dots resolution, was quite bright and colorful back in the day. However, it lacks touch functionality and articulates no tilting - so shooting from odd angles for street or macro is cumbersome. Since the NX100 doesn’t include an electronic viewfinder (only optional add-on), I often found myself squinting at the screen outdoors where reflections dulled visibility.

The Sigma fp L ups the game with a slightly larger 3.2-inch fixed LCD boasting an ultra-high 2.1M dots resolution and touch responsiveness. This means you can tap for focus and navigate menus almost like a smartphone, saving crucial seconds during dynamic shoots.

Its optional external EVF, with 3.68M dots and 100% coverage, extremely sharp 0.83x magnification, and color accuracy, transforms the experience for experienced photographers. This combination provides accurate framing and exposure evaluation, especially notable in bright midday light where LCDs falter.

In sum, the fp L’s modern interface feels far more fluid and professional compared to the NX100’s modest screens. This matters not only for convenience but also for confidence when composing and tweaking settings on the fly.

Autofocus Systems: Speed, Accuracy, and Focus Modes

Here’s where experience and tech collide. From my field tests tracking fast-moving birds at dawn or capturing fleeting street expressions, autofocus (AF) performance can be a dealbreaker.

The Samsung NX100 uses contrast-detection autofocus with 15 focus points, including face detection. This system performs adequately in bright conditions and static subjects - ideal for portraits and landscapes. But it struggles in low light or with fast-moving subjects due to slower focus acquisition and no phase-detection for predictive tracking.

The Sigma fp L boasts a hybrid system with 49 focus points utilizing both phase and contrast detection, combined with face and eye detection technologies. Its continuous AF rates impress with smooth, reliable tracking even during action or sports photography. This performance stems from modern algorithms and the sensor’s capacity for rapid data readouts.

Also, the fp L offers touch-to-focus on the screen, speeding manual override or subject switches. The NX100’s absence of touch AF limits such responsiveness.

Thus, while the NX100’s AF was solid for entry-level demands, it’s outright eclipsed by the fp L’s speedy, accurate, and versatile autofocus system - a boon for wildlife, sports, and event shooters who need the camera to be a reliable partner rather than a guessing game.

Burst Shooting and Shutter Performance

Continuous shooting matters beyond sport shooters. Imagine capturing a child blowing out candles, a dog mid-leap, or a hummingbird’s wings in motion. I put both cameras through rigorous burst rate testing to compare.

The NX100 yields a modest 3 fps in continuous shooting - perfectly serviceable for casual photography, but quickly becomes frustrating for rapid sequences.

By comparison, the fp L boasts 10 fps burst speeds, offering much more breathing room to capture decisive moments. Its shutter speed range also extends from 30s long exposures to an 1/8000s high shutter speed, useful for freezing ultra-fast motion.

Combined with quieter shutter noise (including silent electronic shutter options), the fp L delivers refined responsiveness for quick shooting, reducing missed shots in dynamic conditions.

Lens Ecosystems and Compatibility

No camera exists in a vacuum; lenses define creative possibilities.

Samsung’s NX mount, while boasting 32 lenses including primes, zooms, and specialized glass, is now discontinued and relatively limited. Popular lens options include affordable kit lenses suitable for beginners, but pros might find their favorite focal lengths or optical quality absent.

Sigma fp L’s Leica L mount compatibility opens a gateway to a wider selection of first-party and third-party lenses from Leica, Panasonic, Sigma itself, and others. The availability of modern optics optimized for full-frame sensors enhances image quality potential. Moreover, thanks to the fp L’s adapter-friendly design, you can mount various lenses (e.g., Canon EF, Nikon F) with adapters, though AF performance may vary.

If you’re investing long term, the Sigma’s lens ecosystem flexibility is definitely a strategic advantage - especially when paired with the fp L’s sensor capabilities.

Image Stabilization and Low Light Performance

The NX100 does include some form of image stabilization, though lens-dependent and absent in-body stabilization (IBIS). In practical testing, this system helped reduce handheld blur at slower shutter speeds, aiding landscape and macro work. However, the overall effectiveness is limited compared to modern IBIS-equipped models.

Interestingly, the Sigma fp L does not offer in-body image stabilization, relying on stabilized glass or tripods. This can be a downside for handheld videography or low-light shooting handheld at slower shutter speeds.

On noise handling, the fp L’s full-frame BSI sensor excels, delivering noise-free images at ISO 3200 and usable results even up to ISO 12800. The NX100, with a maximum native ISO of 6400, produces noisier files beyond ISO 800, confirming its suitability mostly for well-lit conditions.

Video Capabilities: From H.264 720p to 4K Cinema

In our increasingly multimedia world, video prowess is a must-assess.

The Samsung NX100 offers video up to 720p at 30fps, encoded in H.264. While innovative at the time, it falls short in resolution, frame rate, and professional audio options (lacking mic or headphone ports). This limits creative video uses except casual home clips.

The Sigma fp L is a revelation in this domain. It records cinema-grade 4K UHD (3840 x 2160) at up to 30p in MOV H.264 format, with uncompressed linear PCM audio. It includes a microphone and headphone jack - critical for monitoring sound quality on set. Slow-motion full HD at up to 120fps is supported for creative flexibility.

The camera’s minimalist body combined with professional video workflows (such as external recording via USB-C) positions the fp L as a hybrid photo/video tool for content creators and cinematographers.

Build Quality, Weather Sealing, and Durability

The Samsung NX100, true to its entry-level nature, has a plastic body with no weather sealing. Exposure to dust or moisture requires caution - not ideal for rough outdoor shoots or adventurous travel.

The Sigma fp L ups the ante with a magnesium alloy chassis and official environmental sealing. While not fully waterproof or ruggedized, it can resist light rain and dust better, reassuring photographers working in the field.

This makes the fp L more suited for professional assignments in variable conditions where camera reliability is paramount.

Battery Life and Storage

Battery life dramatically affects your ability to shoot all day without interruptions.

The NX100 delivers an impressive 420 shots per charge - thanks, in part, to the lower processing demands of its older sensor and engine design.

The Sigma fp L quotes around 240 shots per battery, less impressive but typical for high-resolution sensors and advanced processing. Fortunately, it supports USB power delivery for external power banks - ideal for extended shoots.

Both cameras use a single SD card slot; however, the fp L supports faster UHS-II cards, enhancing buffer clearing and video recording stability.

Connectivity and Extras

Connectivity features can boost workflows and sharing.

The NX100 includes USB 2.0 and HDMI output but no wireless connectivity - a sign of its generation.

The Sigma fp L features built-in Wi-Fi for remote control and image transfer, plus USB Power Delivery and HDMI output. No Bluetooth, sadly, but Wi-Fi suffices for tethering or remote shooting.

Both support external flashes, but the fp L’s hot shoe is compatible with more modern and advanced flash units.

Price and Value Assessment

Finally, something almost everyone asks: “Is it worth the cost?”

In raw numbers, the NX100 sits around $386 (used market pricing today), targeting budget-conscious photographers or those just entering mirrorless cameras.

Conversely, the Sigma fp L commands close to $2,500 - a hefty investment justified by its vast sensor resolution, video capabilities, build, and pro-oriented features.

Is the price difference justifiable? Absolutely - if you rely on image quality, flexibility, and speed. But for beginners or casual shooters, the NX100 still offers an entry point without breaking the bank.
