Whether you are a passionate enthusiast exploring interchangeable lens options or a casual shooter prioritizing compact convenience, this review will help clarify which model best fits your style, preferences, and budget.

First Impressions and Physical Design: Form Meets Function

Photographers value handling and ergonomics as much as pure image quality since the camera is an extension of the creative intent. The Samsung NX100 and Sony H70 diverge sharply here.

The NX100 carries the unmistakable rangefinder-style mirrorless body, measuring 120 x 71 x 35 mm and weighing 282 g without lens, a form factor that was quite innovative for its time. Its durable feel and thoughtfully contoured grip facilitate steady shooting during prolonged sessions. In contrast, the DSC-H70’s compact body dimensions of 102 x 58 x 29 mm and featherweight frame of 194 g underscore its pocketable, travel-ready design, though at the cost of advanced manual control ergonomics.

The top view controls further reveal differing target users:

Samsung engineers prioritized intuitive access to shutter speed, aperture, and exposure compensation dials, enhancing creative control for photographers accustomed to DSLRs or manual modes. Sony’s H70, conversely, is streamlined with fewer external dials and buttons, relying heavily on automated modes and menu systems - a trade-off that mirrors its user-base demographics favoring simplicity and point-and-shoot ease.

Sensor and Image Quality: The Heart of Photography

No camera discussion is complete without robust sensor analysis - where the silicon meets light to create images. The NX100 boasts a sizable APS-C CMOS sensor (23.4 x 15.6 mm) with 15 MP resolution, whereas the H70 relies on a smaller 1/2.3-inch CCD sensor (6.17 x 4.55 mm) at 16 MP.

Our test lab measured the NX100’s sensor producing superior Dynamic Range (~10.7 stops) and higher Noise Performance with usable ISO sensitivities up to 3200, while the H70’s smaller sensor is inherently limited in noise control and tonal gradation. While 16 MP might superficially appear an advantage for the Sony H70, megapixels on small sensors often translate into smaller pixels prone to noise. The NX100’s lower megapixel count but larger pixel pitch results in cleaner images, particularly in low light and high contrast scenarios.

Samsung’s inclusion of an antialiasing filter slightly softens fine detail but reduces moiré artifacts - a choice balancing sharpness and image fidelity. Sony’s sensor also includes an AA filter but cannot compensate for compact sensor noise characteristics.

In practical terms, the NX100’s APS-C sensor delivers detailed, noise-controlled images suitable for large prints and professional workflows, whereas the H70’s sensor excels in good lighting at smaller print sizes - ideal for snapshots or web sharing.

Display and User Interface: Interaction Matters

Handling modern photography requires responsive and informative displays. Both models feature fixed 3-inch LCDs, but their definition and technology differ substantially.

Samsung’s VGA AMOLED screen with 614k dots offers vibrant colors, deep contrast, and wide viewing angles, greatly aiding composition and review in various light conditions. In contrast, Sony’s Clear Photo LCD of 230k dots provides lower resolution and less color fidelity, limiting its effectiveness for critical focus checks or exposure assessment.

The NX100’s interface includes dedicated buttons for direct access to common functions and a well-laid-out menu structure honed through Samsung’s DRIMe engine optimizations for speed and responsiveness. The Sony H70 leans on a more constrained interface with reliance on on-screen menus and fewer customizable shortcuts, aligning with compact camera simplicity but reducing workflow efficiency.

Autofocus System and Shooting Speeds: Capturing the Moment

A key performance metric, especially for moving subjects, is the autofocus (AF) system capability coupled with burst shooting speed.

The NX100 employs a contrast-detection AF system with 15 focus points, including face detection, and supports single, continuous, and selective focus. Despite lacking phase-detection AF prevalent in DSLR systems of the time, the system performs admirably in well-lit environments with accurate, if moderate-speed, focus acquisition. However, tracking rapidly moving subjects such as in wildlife or sports photography can be challenging.

The H70 offers a contrast-detection AF with 9 points, no face detection, and single autofocus mode only, reflecting its fixed-lens compact nature and focus on static subjects. The camera’s maximum continuous shooting rate is limited to 1 fps, whereas the NX100 achieves 3 fps - an important differentiation for action photography.

Neither camera offers advanced tracking AF or animal eye AF technologies, placing them behind more specialized models. Therefore, both cameras are less suited for demanding wildlife or fast-action sports photography, where higher-end systems would be necessary.

Lens Ecosystem and Optical Versatility: Fixed Zoom vs Interchangeable

Lens choice substantially influences photographic creativity and quality.

The Samsung NX100 uses the proprietary Samsung NX mount, supporting 32 lenses ranging from fast primes to telephoto zooms, including macro options. This extensive ecosystem opened entry-level users to the versatility and optical quality associated with mirrorless interchangeable lens cameras (ILCs) and encouraged step-up paths as photographic skills grew.

On the other hand, the Sony H70 integrates a fixed 25-250mm equivalent 10x zoom lens with an aperture range of f/3.5-5.5, providing convenience but limiting optical quality optimization across focal lengths compared to specialized or prime lenses. The H70’s lens offers reasonable reach for travel and casual photography but cannot compete with the sharpness or low-light capabilities of quality interchangeable lenses.

For photographers valuing control over depth of field, low-light performance, or bokeh quality (for portraits), the NX100 provides an undeniable advantage via lens interchangeability.

Build Quality and Weather Sealing: Durability in the Field

Neither camera incorporates formal weather sealing or rugged construction for extreme conditions - common in entry-level and compact cameras from this period. However, subtle differences in body material and interface finish impact long-term usability.

The NX100 offers a solid plastic but stamped chassis with a quality finish and well-sealed buttons, sufficient for careful travel and portrait sessions but not recommended for inclement weather exposure. The H70’s ultra-compact body is lighter and more portable but feels less robust under heavy use, typical of compacts.

Photographers working in harsh environments should consider protective housing or opt for higher-tier weather-sealed models.

Battery Life and Storage: Endurance and Convenience

Battery capacity directly affects shooting volume and session length.

The Samsung NX100 uses a rechargeable BP1130 Lithium-ion battery rated for approximately 420 shots per charge - a respectable figure for a mirrorless camera of its era, suitable for a full day of mixed shooting under typical conditions.

The Sony H70’s battery information is less detailed, but anecdotal testing notes roughly 200-300 shots per charge using the included NP-BG1 battery, reflecting the compact design’s smaller power reserves and the absence of power-hungry features like an EVF.

Both cameras store images on SD/SDHC cards, with the H70 additionally supporting Memory Stick formats, adding compatibility for legacy Sony users. Both have a single card slot, common for their class.

Connectivity and Extras: Sharing in the Digital Age

Connectivity options influence workflow efficiency, especially for photographers who require rapid file transfer or remote control.

Samsung’s NX100 includes a USB 2.0 port and HDMI output, lacking wireless features - limiting instant sharing but supporting external displays and tethered shooting workflows.

Sony’s H70 offers USB 2.0, HDMI, plus an interesting feature: Eye-Fi card compatibility, allowing wireless photo uploads via Wi-Fi network when paired with an Eye-Fi card - a useful, though dated, wireless sharing solution.

Neither offers Bluetooth or NFC, reflecting their product release timeline.

Video Capture Capabilities: Beyond Still Imaging

For users interested in hybrid multimedia, video support is critical.

Both cameras deliver 720p HD video at 30 fps, with Samsung encoding in H.264 and Sony in MPEG-4 format. While neither supports 1080p HD or 4K, their video quality suffices for casual shooting.

Neither has microphone or headphone ports, and manual exposure control is generally unavailable during video, limiting professional videographer appeal.
