Announced in 2012 and 2013 respectively, these cameras continue to attract attention for their imaging capabilities, design choices, and suitability across a spectrum of photographic disciplines. Drawing upon over 15 years of rigorous camera testing experience and firsthand evaluation of thousands of imaging devices, this comprehensive comparison draws out the nuanced differences, real-world performance dynamics, and value proposition that each offers. Our goal is to equip photographers - from passionate enthusiasts to seasoned professionals - with the detailed insights needed to navigate the choice between these two technologically strong yet conceptually distinct cameras.

First Impressions and Ergonomic Design: Style Meets Substance

The user experience usually begins with the body design and ergonomics, and the Samsung NX20 versus Sony RX1R comparison reveals divergent approaches tailored for different use cases.

The Samsung NX20 adopts a traditional SLR-style mirrorless body with a deep grip and thoughtfully arranged tactile controls designed for photographers accustomed to DSLR ergonomics. Despite being mirrorless, it sustains a familiar shape and control feel, facilitating rapid access to key settings such as shutter speed, aperture, and ISO via dedicated dials and buttons - a crucial advantage when shooting fast-moving subjects or in dynamic environments.

Conversely, the Sony RX1R embraces minimalism as a large sensor compact camera with a fixed lens, deliberately crafted for maximum portability and stealth. It eschews DSLR-style grips for a more modest form factor, favoring quick point-and-shoot convenience. The RX1R's body fits easily in a jacket pocket or small bag, making it ideal for street photography and travel where discretion and light weight are prioritized. However, this compactness comes with the trade-off of fewer physical controls and a smaller grip area, which might challenge users with larger hands or those who prefer extensive manual operation.

Evaluating physical dimensions confirms these observations: the NX20 measures 122 x 90 x 40 mm, weighing a relatively light 341g, while the RX1R, though smaller footprint-wise at 113 x 65 x 70 mm, weighs a heftier 482g due to its larger full-frame sensor and metal chassis. The difference in body thickness and grip design influences handling comfort, especially during prolonged sessions.

On balance, users valuing tactile shooting experience and lens interchangeability will appreciate the NX20’s ergonomic strengths, whereas photographers prioritizing compactness and rapid discreet shooting may lean towards the RX1R.

Sensor and Image Quality: APS-C Versatility vs. Full-Frame Excellence

At the heart of any camera’s imaging prowess lies its sensor. Here, a fundamental divergence defines the NX20 and RX1R’s characteristics - the NX20 employs a 20MP APS-C CMOS sensor (23.5 x 15.7 mm, 368.95 mm² sensor area) with an integrated anti-aliasing filter, while the RX1R boasts a 24MP full-frame CMOS sensor (35.8 x 23.9 mm, 855.62 mm²), notably sans an anti-aliasing filter, enhancing resolution sharpness.

The RX1R’s larger sensor size inherently affords superior light-gathering ability, lower noise at elevated ISOs (up to 25600 native), and a wider dynamic range, confirmed by DxOMark scores of 91 overall, 25 color depth, and 13.6 EV dynamic range. In contrast, the NX20’s APS-C sensor earns a respectable DxOMark overall of 75 with a color depth of 23.4 and 12.9 EV dynamic range - impressive for its class and era, but objectively behind the RX1R’s sensor.

Practitioners evaluating image quality in skin tones and color reproduction will find the RX1R excels thanks to its larger sensor and lack of anti-aliasing filter, delivering crisp detail and smoother gradations - especially prized in portraiture and fine art photography. The NX20 performs admirably, producing vivid colors and solid dynamic range for its sensor size but may show slight moiré in very fine textures due to the anti-aliasing filter.

In real-world testing, the RX1R produces noticeably cleaner files at ISO 1600 and above, critical for low-light, night, and astro photography, whereas the NX20 begins to display visible noise earlier, making it better suited for well-lit environments or where noise reduction post-processing is acceptable.

Autofocus Performance and Precision: Contrast Detection Versus Hybrid Systems

Autofocus capability remains a pivotal factor, influencing how effectively a camera responds to varied shooting scenarios.

The Samsung NX20 relies on a 15-point contrast-detection autofocus system with face detection capabilities, operating well in live view mode but lacking phase-detection focusing. This configuration translates into accurate but sometimes slower focusing, particularly in low-light or fast-action contexts where contrast-based AF traditionally lags.

Sony’s RX1R, while also contrast-detection based with 25 focus points, augments its system with tracking autofocus and face detection optimized for full-frame. However, it does not support continuous autofocus modes for video and offers single AF priority in stills. Despite these limitations, in practice, RX1R’s contrast-detect AF delivers precise focus with its fixed 35mm f/2 lens, assisted by the camera’s well-tuned algorithms.

Neither camera includes cutting-edge phase-detection autofocus or hybrid AF systems popular in later generations or professional-grade models, meaning both may struggle with unpredictable, high-speed subjects like wildlife or sports. The NX20’s 8 fps continuous shooting rate surpasses the RX1R’s 5 fps, compensating somewhat for its lesser AF tracking in burst scenarios.

For portrait and general-purpose shooting, both cameras provide dependable autofocus accuracy, particularly with face detection engaged on human subjects. However, for wildlife or sports photographers requiring rapid, responsive tracking, neither is ideal - but the NX20’s higher burst rate may offer marginal advantages.

Handling and User Interface: Controls, Display, and Viewfinder

Physical handling extends beyond ergonomics into screen quality, viewfinders, and controls.

The Samsung NX20 incorporates a fully articulated 3-inch Active Matrix OLED screen with 614k-dot resolution, highly versatile for composing at awkward angles and selfies (a noted feature). Its 0.7x EVF with 100% coverage complements this setup, delivering a stable and clear preview under varied lighting.

The Sony RX1R employs a fixed 3-inch Xtra Fine TFT LCD with 1,229k dots, providing better pixel density for sharper on-screen review but lacks articulation. Notably, the RX1R does not include a built-in electronic viewfinder, relying instead on an optional add-on optical viewfinder, which may be viewed as a limitation for eyepiece composition in bright outdoor conditions.

In terms of physical controls, the NX20 uses a combination of dedicated dials and buttons providing quick access to exposure modes, ISO, and white balance, suited for photographers preferring manual control. The RX1R offers fewer controls due to its form factor and fixed lens, leaning more on menu navigation for adjustments.

For users prioritizing an articulated screen or integrated EVF, the NX20 clearly leads, aiding versatility in portraits, macro, and diverse shooting postures. Conversely, the RX1R’s higher resolution screen excels for detailed image review.

Lens Ecosystem and Focal-Length Flexibility

Lens compatibility remains a cornerstone for photographers seeking adaptability or specialized optics.

The Samsung NX20 mounts Samsung’s NX lens system with 32 available lenses covering wide-angle to telephoto ranges, including prime and zoom options. The 1.5x crop factor necessitates consideration when composing focal lengths, but the extensive lens range allows the user to tailor their setup for portrait, landscape, wildlife, and macro applications, making the NX20 a versatile system camera platform.

The Sony RX1R, by contrast, offers a fixed, high-quality 35mm f/2 lens - a classic focal length prized for documentary, travel, and street photography, delivering excellent sharpness and low-light performance. However, the lack of lens swaps restricts creative framing flexibility and specialty niches like extreme telephoto wildlife or macro work.
