Samsung NX1 vs Sony RX100 IV: An Expert's Deep Dive into Two Very Different Cameras

In my 15+ years of hands-on experience testing cameras, I’ve learned that comparative reviews can be both illuminating and challenging - especially when devices differ so radically in design, target audience, and technical approach as the Samsung NX1 and Sony RX100 IV. While it may seem unorthodox to compare a flagship APS-C mirrorless system camera to a premium 1-inch sensor compact, both hit the market when innovation in sensor design and video capabilities were accelerating. As a long-time camera tester and professional photographer, I take you through a detailed, real-world examination of these two machines to uncover what they really deliver across the full spectrum of photography disciplines.

Let’s jump right in.

When Size and Design Matter: Handling and Ergonomics

Physical design has a profound impact on how a camera feels during prolonged shoots or fast-paced moments. The Samsung NX1 sports a SLR-style mirrorless body with a robust magnesium alloy frame, designed to compete in the professional league. Meanwhile, the Sony RX100 IV offers a compact, pocketable body aimed at travelers and enthusiasts who prioritize portability.

Right away, the Samsung NX1’s bulk (139 x 102 x 66 mm, 550g) contrasts sharply with the petite RX100 IV (102 x 58 x 41 mm, 298g). The NX1’s deep grip and numerous dedicated buttons provide excellent tactile feedback, making it a joy for manual control in the field. Meanwhile, the RX100 IV’s compactness is a double-edged sword: it’s incredibly convenient for carrying everywhere, but the smaller body limits physical controls and the overall handling experience feels more “point-and-shoot.”

The top-view comparison further highlights their ergonomic philosophies. The NX1 features a comprehensive control layout with a top LCD for quick status checks and two command dials facilitating quick exposure adjustments in modes like aperture and shutter priority. The RX100 IV’s top plate is minimalist, trading physical dials for menus and on-screen controls - typical for compacts designed for simplicity over speed.

Practical takeaway: If you’re a photographer who values manual control and using physical dials without fumbling through menus, the NX1 feels far more intuitive. For travelers or street photographers wanting a lightweight carry-everywhere camera, the RX100 IV wins on portability, but with compromises on ergonomics.

Sensor Technology and Image Quality: The Heart of the Camera

The NX1’s 28MP APS-C BSI-CMOS sensor dwarfs the RX100 IV’s 20MP 1-inch (13.2 x 8.8mm) sensor in both physical dimensions and resolution. Image quality differences are evident not just on paper but in practical shooting scenarios.

The larger sensor area of the NX1 (368.95 mm² vs 116.16 mm²) translates to better light-gathering efficiency, which helps with dynamic range, noise control, and depth of field control. According to DxOMark benchmarks, the NX1’s sensor scores 83 overall compared to 70 for the RX100 IV. This translates practically into:

• Enhanced dynamic range (13.2 EV vs 12.6 EV), critical for landscape and high-contrast scenes.
• Superior low-light performance (DxO low-light ISO 1363 vs 562), meaning cleaner images at higher ISO during night or indoor shooting.
• Greater color depth (24.2 bits vs 22.9 bits), benefiting skin tones and color fidelity in portraits.

The NX1’s lack of an anti-aliasing filter results in perhaps slightly crisper images but may introduce moiré in certain patterns, while the RX100 IV employs such a filter for artifact control.

My testing notes: In portrait sessions, the NX1 rendered skin tones beautifully with subtle gradations and excellent detail, while the RX100 IV, though sharp, had a somewhat tighter depth of field control due to the smaller sensor and fixed lens - limiting the creamy bokeh.

Viewing Experience: LCD Screens and EVFs

Both cameras feature 3-inch tilting displays, but they differ subtly in resolution and touchscreen capability. The NX1’s 1036k-dot touchscreen allows fingertip focus point setting and quick menu access. The RX100 IV’s slightly higher resolution 1229k-dot screen is not touch-enabled, which affects the responsiveness of focusing and navigation.

Electronic viewfinders on both are OLED, with near-identical resolutions (~2360k dots), providing bright, high-contrast images with 100% coverage. However, the NX1 boasts a larger 0.7x magnification versus 0.59x on the RX100 IV, contributing to a more immersive framing experience.

The NX1’s EVF size and eye sensor helped during long shoots, reducing eye fatigue and allowing fast composition changes. The RX100 IV EVF, while handy for bright environments, felt cramped after extended use.

Pro tip: If you rely heavily on EVFs for manual focus precision or critical framing in challenging outdoor light, the NX1’s viewfinder is noticeably more comfortable and capable.

Autofocus Performance: Speed, Accuracy, and Tracking

Autofocus systems are crucial, especially for wildlife, sports, and street photographers who require fast, reliable focus tracking.

The Samsung NX1 contains a hybrid AF system integrating 209 focus points (153 cross-type), blending phase-detection and contrast detection. This combination offers speedy initial locking and fine-tuned precision. Face detection and touch AF support enable accuracy in varied lighting.

The RX100 IV uses a contrast-detection-only system with 25 autofocus points; phase detection is absent. While contrast AF can be accurate, it generally lags in speed compared to hybrid systems, especially continuous tracking configurations.

Burst shooting speeds: The RX100 IV maxes out at 16 fps vs NX1's 15 fps; however, NX1’s advanced AF system maintains better focus coherence in continuous modes.

In my wildlife tests, tracking fast-moving birds in flight, the NX1 repeatedly nailed focus with steady tracking, while the RX100 IV struggled after a few frames, showing hunting behavior common to contrast-only systems. For street photography, the RX100 IV’s rapid burst facilitated moments of serendipity, though AF lag was occasionally noticeable in low light.

Optics and Lens Ecosystem

Samsung’s NX mount system offers 32 lenses, ranging from superwide primes and telephotos to specialized macro optics. The NX1 accepts these lenses natively, supporting fast apertures and optical stabilization where available.

In contrast, the RX100 IV has a fixed 24-70mm equivalent f/1.8-2.8 Zeiss-branded zoom lens. While outstanding for its class, this limits versatility. The excellent lens offers sharpness and close focusing (macro from 5 cm) but cannot match the creative flexibility of interchangeable lens systems.

The NX1 lacks in-body image stabilization (IBIS), so stabilization depends on the lens. The RX100 IV includes optical steady shot stabilization built into its lens, valuable given the absence of lens swaps.

For macro closeups, the RX100 IV’s fast aperture and 5 cm macro focusing make it surprisingly capable, but the NX1 paired with specialized macro glass delivers greater detail and compositional freedom.

Durability and Weather Sealing

The NX1 incorporates environmental sealing and dustproofing - vital for professional outdoor photographers shooting in inclement weather. I’ve taken the NX1 on rainy hikes without concern for water ingress or dust damage.

The RX100 IV lacks any weather sealing. It’s a camera that requires more cautious handling, better suited for casual environmental conditions.

Video Capabilities: 4K and Beyond

Both cameras record 4K UHD video; however, their codecs and video-centric features differ substantially.

Samsung NX1 offers 4K recording at 30p and 24p with HEVC/H.265 compression, a relatively advanced codec that better manages file sizes without sacrificing image quality. It supports microphone and headphone jacks, essential for serious vloggers or filmmakers, and includes built-in time-lapse recording.

The RX100 IV records 4K at 30p and 25p using MPEG-4, AVCHD, and XAVC S codecs. Despite supporting high frame rates up to 120p at HD resolution, it lacks external mic/headphone ports, limiting audio quality options for professionals.

In my tests, the NX1’s 4K footage exhibited richer gradations and cleaner low-light performance with less noise than the RX100 IV - expected given the larger sensor and newer codec.

Battery Life and Storage

Samsung’s BP1900 battery achieves approximately 500 shots per charge, which aligns with professional mirrorless standards and allows for extended sessions. It accepts standard SD cards (UHS-I/II) in a single slot.

The RX100 IV utilizes the smaller NP-BX1 battery, rated around 280 shots, which is typical for compacts but requires frequent charger access for day-long shoots. It accepts SD and Memory Stick cards.

For travel and event photography, the NX1’s longer battery life and faster USB 3.0 connectivity for data transfers can be notably advantageous.
