Photography enthusiasts and professionals often face a perplexing choice when considering compact but potent cameras that promise to elevate their creative endeavors without the bulk of DSLR systems. Two such compelling yet fundamentally different devices are the Samsung NX20, an advanced mirrorless camera with a traditional SLR-style body, and the Sony Cyber-shot DSC-QX100, a unique lens-style camera designed to interface with smartphones.

Drawing upon over 15 years of hands-on camera evaluations across multiple photographic disciplines - ranging from portraiture to wildlife and landscape photography - I present a detailed comparative analysis of these two cameras. This in-depth review balances technical nuance and practical insights gleaned from rigorous field testing to help you understand which camera aligns with your photographic goals, budget constraints, and workflow preferences.

First Impressions: Design, Ergonomics, and Handling

Photography gear isn’t just about specs but how comfortably and intuitively you operate the camera in varied shooting scenarios. The Samsung NX20 embraces a classic SLR-style mirrorless design, while the Sony QX100 is an unconventional lens-style camera reliant on smartphone integration.

Samsung NX20: Measuring 122 x 90 x 40 mm and weighing approximately 341 grams (excluding lens), the NX20 feels compact yet substantial, modeled after traditional DSLR ergonomics with a pronounced grip and tactile buttons. Its fully articulated 3-inch OLED display offers excellent viewing angles and sharp detail, complementing the electronic viewfinder boasting full 100% coverage, which adds to composition precision.

Sony QX100: This device defies conventions with a lens-style form factor measuring about 63 x 63 x 56 mm and a lighter weight of 179 grams. It lacks an integrated screen or viewfinder, relying entirely on smartphone live view and control via a dedicated app. This minimalist approach yields ultimate portability and discretion but comes at the expense of standalone usability and tactile controls.

In usability testing, the NX20's physical controls and distinct dials for shutter, aperture, ISO, and exposure compensation translate to faster manual adjustments, a critical advantage for professionals and enthusiasts demanding efficiency. Conversely, the QX100 requires frequent screen tapping and gesture-based commands, which, while convenient for casual snapshots, can challenge precise manual control, particularly in demanding environments.

Sensor and Image Quality: Size Matters but So Does Technology

Image quality remains paramount for photographers. Sensor size, resolution, and onboard processing significantly influence dynamic range, noise handling, color fidelity, and ultimately print or screen output.

• Samsung NX20 boasts a large APS-C CMOS sensor measuring 23.5 x 15.7 mm with a 20-megapixel resolution and an anti-aliasing filter. This sensor dimension provides a solid canvas for superior image quality, greater control over depth of field, and excellent noise performance at higher ISO - up to 12,800 native sensitivity. DxOMark rates its color depth at an impressive 23.4 bits and dynamic range at about 12.9 EV stops, offering photographers a wide tonal capture capable of nuanced shadow and highlight retention.

• Sony QX100 integrates a smaller but nonetheless capable 1-inch BSI CMOS sensor (13.2 x 8.8 mm) also with 20 megapixels and an anti-aliasing filter. BSI (Backside Illuminated) design improves low-light sensitivity, but the sensor’s smaller area (116.16 mm²) limits noise control and dynamic range compared to APS-C. The maximum ISO tops out at 6400, which is respectable but somewhat limiting for night or astrophotography.

For landscape or studio photographers prioritizing image latitude and fine detail, the NX20 sensor clearly offers the advantage. The QX100 can still challenge compact cameras and smartphones significantly, producing impressively sharp images in favorable light, but it cannot compete with APS-C-grade detail or low-light latitude.

Shooting Experience: Autofocus, Burst, and Low Light Performance

A camera’s autofocus system, burst rate, and noise handling capabilities underpin its suitability for action, wildlife, and sports photography.

While neither camera incorporates modern phase-detection autofocus, the NX20’s 15-point contrast-detection AF with face detection is moderately quick and accurate in good light conditions but struggles with continuous-tracking moving subjects due to lack of hybrid or phase detection.

Its 8 fps burst rate offers respectable performance for basic sports or action photography; however, buffer limitations inhibit extended sequences. The QX100 lacks continuous shooting altogether and is focused more on casual shooting and enhanced portability rather than speed or tracking precision.

Low-light performance favors NX20’s larger sensor with cleaner files at high ISO values enabling more aggressive exposure settings, while QX100’s optical image stabilization helps compensate for camera shake but cannot mitigate sensor noise limitations fully.

Build Quality and Weather Resistance: Can They Handle Rough Use?

Both cameras are not designed with professional-grade environmental sealing.

• Samsung NX20 offers solid construction with a lightweight magnesium alloy body, though without official weather sealing or dust protection. Users should exercise caution when shooting in rain or dusty environments.

• Sony QX100, built primarily as an add-on lens module, has a plastic and metal finish but no weather or splash resistance; its dependence on smartphone connectivity also introduces practical limitations in harsh conditions.

Neither camera is shockproof, freezeproof, or crushproof, reflecting their consumer-focused design ethos.

User Interface and Display: The Control Center for Photographers

Photographers spend hours interfacing with their cameras; therefore, the responsiveness and intuitive layout of controls are critical.

• The Samsung NX20 features a highly functional top-plate with traditional dials for quick mode, shutter speed, aperture, and an ISO button. The OLED articulated screen supports touch focus, tilt, and swivel, enhancing compositional flexibility. The electronic viewfinder provides critical eye-level framing and easier manual focusing on the lens.

• The Sony QX100 forgoes physical controls beyond the shutter release and zoom rocker on its compact body. Most exposure and focus adjustments are made through the companion app on the connected smartphone, which integrates touchscreen capabilities and live view. While innovative, this reliance complicates rapid manual adjustments and can be a bottleneck when the phone’s battery or Wi-Fi connection underperforms.

Ergonomically, the NX20 is undoubtedly more comfortable for extended use, offering illuminated buttons and dedicated physical controls that photographers expect. The QX100, meanwhile, prioritizes minimalism and portability, trading off direct tactile feedback for smartphone convenience.

Lens Ecosystem and Focal Flexibility: Versatility on Demand

A camera’s lens mount and compatible optics dictate the range of achievable perspectives and creative control.

• The Samsung NX20 uses the proprietary Samsung NX lens mount, which, during its lifecycle, amassed a respectable system of 32 native lenses ranging from ultra-wide primes to telephoto zooms and specialized macro optics. This variety empowers photographers to select lenses tailored for portraits, landscapes, macro work, or wildlife, thereby enhancing the camera’s adaptability.

• The Sony QX100 is a fixed-lens camera featuring a 28–100 mm (equivalent) F1.8-4.9 zoom lens with a modest 3.6x optical zoom. Although the lens offers a fast aperture for primetime low light capability and some creative background separation, the lack of interchangeability confines photographers to the single integrated optic.

Thus, from a practical standpoint, the NX20’s system provides superior creative freedom and the ability to upgrade incrementally, while the QX100 serves as a compact, pocketable solution ideal for casual shooters or smartphone users seeking improved image quality without bulk.

Battery Life and Storage: Shooting Endurance for Real-World Use

Shooting longevity is the foundation for workflows that involve extended sessions, whether travel or events.

Our hands-on testing corroborates these manufacturer claims: the NX20’s battery comfortably supports half-day or longer shooting under moderate use, while the QX100 often requires more frequent battery changes during intensive use due to its smaller capacity and the drain of Wi-Fi connectivity.

Storage format variety also matters: the NX20 supports full-sized SD cards, which tend to be faster and offer higher capacities, advantageous for high-resolution RAW files. The QX100 uses microSD types, more compact but sometimes slower, impacting burst shooting or video file transfer speeds.

Connectivity and Wireless Features: Modern Workflow Integration

The Wi-Fi-enabled nature of both cameras plays distinct roles in how you can transfer images and control the camera remotely.

• The Samsung NX20 comes with built-in Wi-Fi (no Bluetooth or NFC), allowing direct image sharing and remote control via Samsung’s proprietary app. HDMI output facilitates tethered viewing or external recording but no headphone port is present for audio monitoring during video capture.

• The Sony QX100 also includes built-in Wi-Fi and supports NFC pairing for seamless smartphone connections. The camera lacks HDMI or microphone inputs, limiting video production flexibility, and relies solely on the connected device for interface and control.

Professionals prioritizing tethered shooting or robust audio/video workflows will find the NX20 more accommodating due to its dedicated ports and physical controls, while casual or travel users seeking social media integration might appreciate the QX100’s simplified wireless connection.

Video Capabilities: From Vlogging to Casual Clips

Both cameras provide Full HD video recording but differ greatly in their approach and feature set.

• Samsung NX20 records up to 1920 x 1080 resolution at 30 fps, using MPEG-4 and H.264 codecs, including options for multiple frame sizes and frame rates (24 fps, 30 fps, 720p, etc.). Although it lacks 4K video, the NX20 incorporates microphone input and basic manual exposure controls during filming, supporting better sound recording and exposure adjustments. No headphone output reduces monitoring but is common in cameras of this era.

• The Sony QX100 also offers 1080p at 30 fps in MPEG-4 format, but with no audio input options and control limited via smartphone app. Optical image stabilization on the lens aids handheld shooting but limited control and lack of true manual video exposure demand a more casual approach.

Videographers seeking a semi-professional tool for hybrid photo/video projects will gravitate towards the NX20 for its greater control suite and expanded codec options, while the QX100 suits smartphone-centric creators wanting photographic upgrades rather than full video production.
