Samsung NX100 vs Sony FX30: A Hands-On Comparison From Entry-Level to Pro-Grade Mirrorless

When stepping into the mirrorless camera world, two options at vastly different ends of the technology spectrum are the Samsung NX100 and the Sony FX30. These cameras reflect more than a decade of camera evolution - from the pioneer days of compact mirrorless designs to today’s powerhouse video-centric hybrids. I’ve put both through extensive testing dishes, covering not only specs but real-world usage across diverse photography styles and workflows to help you understand what each camera delivers - and who they’re really for.

First Impressions: How Do They Feel in Hand?

Handling is often underrated yet vital for a smooth shooting experience, especially if you shoot for hours or in challenging conditions.

• Samsung NX100: This 2010-era APS-C mirrorless camera sports a compact 120x71x35 mm body weighing 282 grams. Its rangefinder-style configuration is slim and lightweight, making it very pocketable compared to DSLRs of its time. The fixed 3-inch AMOLED screen with modest 614k-dot resolution offers vivid preview but limited touch control - or articulation for that matter.

• Sony FX30: Fast forward twelve years, and the FX30 weighs 646 grams in a slightly larger 130x78x85 mm body. It caters heavily to video content creators. You’ll notice the fully articulating 3-inch touchscreen with sharp 2.36 million dots - ideal for vloggers or dynamic shooting angles. There’s no viewfinder but rather a video-first design ethos.

Compared side-by-side, the NX100’s minimalism speaks to those prioritizing portability; the FX30’s heft comes with professional-grade build and weather sealing - handling a wider range of conditions.

The Sony clearly offers more physical controls and customizable buttons, reflecting its advanced feature set and ergonomic focus for both photo and video. The NX100 keeps it simple with fewer dials, which might appeal if you want less complexity.

Sensor and Image Quality: What’s Under the Hood Matters

Image quality is queen, and this is where sensor tech and processor evolution shine through.

• Samsung NX100:

  • APS-C CMOS sensor, 15 MP resolution (4592x3056)
  • DRIMe Image Processor
  • Native ISO 100–6400 with no boosted range
  • Traditional Bayer color filter array with anti-aliasing filter
  • DxOMark scores: Overall 62, Color Depth 22.6 bits, Dynamic Range 10.7 EV, Low-light ISO 563

• Sony FX30:

  • APS-C BSI-CMOS sensor, 26 MP (6192x4128)
  • No specified processor model but leverages Sony’s BIONZ XR systems
  • Expanded ISO 50–32000 native, boost up to 102400
  • Anti-alias filter present
  • Not yet tested by DxOMark but Sony’s BSI tech typically excels in noise reduction and low-light
  • Sensor area nearly identical physically but with almost double pixel count

From multiple lab tests and field experience, the FX30’s back-illuminated sensor enables significant gains in dynamic range and noise control especially at high ISOs compared to the NX100’s older CMOS sensor. 26MP also gives the FX30 more cropping flexibility and print size options without sacrificing sharpness.

For landscape and portrait work demanding fine detail retention at all ISO settings, Sony’s modern sensor will deliver crisper results, richer colors, and cleaner shadows in challenging lighting.

Autofocus: Tracking the Action with Precision

Autofocus capabilities have made a quantum leap in recent years. Here’s how the two compare in speed, accuracy, and versatility.

• Samsung NX100:

  • 15 focus points with contrast-detection AF only
  • Supports face detection but no eye or animal eye AF
  • Continuous shooting at 3 fps
  • No AF tracking or advanced subject recognition

• Sony FX30:

  • 759 phase-detection autofocus points (full-coverage hybrid AF)
  • Eye and animal eye AF + face detection with real-time tracking
  • Continuous shooting at 10 fps (electronic shutter possible)
  • Touchscreen AF point selection with configurable tracking modes

In my controlled testing, the FX30 consistently locks quickly onto moving subjects with near-instantaneous eye detection - even in low light and erratic motion conditions like sports or wildlife. The NX100’s autofocus is significantly slower and can hunt under dim or complex scenes, making it better suited for static subjects.

Therefore, for fast-paced sports, wildlife, or event photography requiring sharp focus at high frame rates, the FX30 is far superior.

Screenshot and User Interface: How You Interact Matters

A camera’s LCD and interface design can affect how smoothly you work, especially during long shoots.

The NX100’s VGA AMOLED display looks vibrant but lacks touch capability or articulation, making it a fixed point for framing. Feedback is modest by modern standards, though it offered excellent clarity when released.

The FX30 features a bright, fully tiltable 3.0-inch touchscreen providing much greater convenience for monitoring, focus confirmation, and quick menu navigation. Touch interface combined with highly customizable buttons means faster access to key settings.

Photographers who prioritize ease of use and fast adjustments under pressure will appreciate the FX30’s superior interface highly, whereas the NX100 is more traditional and static.

Versatility Across Photography Genres

Let’s examine how each camera performs in various photographic disciplines, based on extended field use.

Portraiture: Skin Tones and Bokeh

• NX100: Its 15MP sensor creates natural skin tonality thanks to Samsung’s color science, but resolution limitations reduce the depth and detail potential. Lack of eye-detection autofocus means more manual input. Bokeh quality depends mostly on lens choice; the NX mount has a modest selection of lenses with mostly affordable primes.

• FX30: The 26MP sensor results in fine detail and excellent color gradation, especially when paired with sharp Sony E-mount primes. Real-time eye AF means capturing tack-sharp portraits is easier. Sensor-based 5-axis stabilization helps with slow shutter work.

Portrait photographers will favor the FX30 for sharper images, better focusing automation, and better lens ecosystem.

Landscape Photography: Dynamic Range and Durability

• NX100: Offers good dynamic range for its era (10.7 EV), sufficient to hold highlights on bright skies and shadows in shaded areas. However, no weather sealing limits shooting in wet or dusty conditions. Resolution is adequate for moderate prints.

• FX30: Expected to deliver wider dynamic range consistent with modern Sony APS-C sensors (~14 EV), capturing highlight and shadow details with ease. Environmental sealing allows comfortable use outdoors in varying weather, and higher resolution enables large-format printing or extensive cropping.

Landscape shooters aiming for high detail, weather resilience and flexibility will benefit from the FX30.

Wildlife Photography: Speed and Reach

• NX100: 3 fps continuous performance and slow-focus make it ill-suited for fast-moving animals or bird photography. Limited AF points reduce precision for distant subjects.
