Samsung HZ30W vs Sony NEX-3: A Hands-On Comparative Review for the Discerning Photographer

Choosing a camera is never a simple game of specs-on-paper. Over my 15+ years of testing everything from pocket compacts to professional mirrorless rigs, I've learned that the true story lives in how a camera performs across diverse shooting scenarios and user demands. Today, we pit two fascinatingly different cameras - the Samsung HZ30W superzoom compact and the Sony NEX-3 entry-level mirrorless - against each other to help you decide which might suit your photographic passions. Though both launched in the early 2010s, they cater to quite different styles and techniques, and that makes the comparison all the more interesting.

Let’s dive deep: ergonomics, sensor tech, autofocus, image quality, video, and more - systematically breaking down strengths, compromises, and who wins in what context. No jargon fluff, just clear-eyed, hands-on insights to help you make an informed choice.

First Impressions and Handling: Pocketable Zoom Versus Interchangeable Modularity

At a glance, these two cameras address different photographer needs. The Samsung HZ30W slips easily into a large jacket pocket with its compact, lightweight body - measuring 107x61x28 mm and weighing a feather-light 245g. Its fixed 15x optical zoom lens (24-360mm equivalent) offers incredible versatility without changing lenses. Handy, yes, but the ergonomics are simple; the body feels plastic and utilitarian, which suits casual shooters and travel photographers prioritizing convenience over tactile refinement.

Compare that with the Sony NEX-3’s more substantial dimensions (117x62x33 mm) and weight (297g). It wears its mirrorless heritage proudly, sporting a rangefinder-style design with a substantial grip and interchangeable lens mount. Handling immediately feels more deliberate and flexible. This camera invites you to build a system - choosing from a broad Sony E-mount lens lineup (over 120 lenses available at launch) to tailor your creative toolkit.

Holding the two side-by-side, you feel the director’s chair of the NEX-3 versus the grab-and-go compact of the HZ30W. For photographers who prize portability and zoom reach bundled into one, HZ30W shines. For those valuing creative control and growability, the NEX-3 beckons.

Sensor Technology and Image Quality: Small Sensor Zoom vs APS-C Mirrorless

Where these cameras differ most fundamentally is their imaging core. The HZ30W sports a 1/2.3-inch CCD sensor with 12MP resolution - common in compact superzoom cameras of the 2010 era. It’s small (sensor area: ~28 mm²), limiting noise control, dynamic range, and color depth compared to larger sensors.

In contrast, the NEX-3 boasts an APS-C CMOS sensor measuring 23.4 x 15.6 mm (~365 mm²), roughly 13 times larger area, and a modestly higher 14MP resolution. This sizeable sensor advantage grants better light gathering, higher native ISO sensitivity (up to 12800), less noise in low light, and superior tonal range.

Hands-on imaging tests confirm these theoretical differences vividly: The NEX-3 delivers clear, crisp images with nuanced colors and superior low-light performance even at ISO 1600–3200. Meanwhile, the HZ30W images tend to struggle in dim conditions, with higher noise at ISO 800 and above, and an inherent softness due to the small sensor and lens design.

Dynamic range also differs materially: The NEX’s APS-C sensor captures richer shadow and highlight detail, a boon for landscapes and high-contrast scenes, whereas the Samsung’s limited range demands more careful exposure to avoid clipping.

If image quality is your principal concern - especially beyond casual snapshots - the NEX-3 takes a clear lead here. The HZ30W’s convenience is offset by compromised tonal fidelity and ISO performance.

Autofocus and Shooting Performance: From Contrast-Detect to Speedy Servo

Autofocus performance is the pulse of shooting spontaneity. For the Samsung HZ30W, what we get is a fairly basic contrast-detection AF system with single-shot and some tracking modes, but no face detection. This means slower focus lock, especially in low light or with moving subjects. The zoom lens’s long reach helps get closer, but the slower AF often frustrates action or wildlife shots.

The Sony NEX-3 incorporates a contrast-detection AF system with 25 focus points and includes face detection. While not blazing fast by today’s standards, it’s significantly more responsive and accurate, especially for static and mildly dynamic subjects. The absence of phase detection (typical of early mirrorless models) limits tracking in fast sports scenarios, yet continuous AF helps maintain focus for casual video or portrait shooting.

Continuous burst shooting also differs starkly: The NEX-3 achieves 7fps (frames per second), allowing capture of fast sequences - useful in sports or wildlife - whereas the HZ30W lacks defined continuous shooting specs, practically limiting burst shots.

For action shooters or wildlife enthusiasts, the NEX-3 is clearly more capable, offering faster focus acquisition and higher frame rates.

Viewfinding and Display: Clear Preview vs Basic Fixed Screen

Neither camera offers an electronic viewfinder, which in 2010 was more typical of entry-level or compact models. Both rely on LCD screens for composition and review.

The Samsung HZ30W uses a fixed 3-inch LCD with low resolution (230k dots), producing a dimmer, less detailed preview. Combined with its limited touchscreen capabilities (none), it restricts ease of navigation and framing in bright conditions.

The Sony NEX-3 advantages itself here with a tilting 3-inch TFT Xtra Fine LCD, boasting a high resolution (920k dots), delivering a crisp, bright viewing experience with adjustable angles. This flexible screen enhances compositional freedom, especially when shooting at unconventional angles or in bright sunlight.

This upgrade in display technology translates directly to practical usability: previewing shots, setting menus, and manual focusing all feel smoother and more precise on the NEX-3.

Lens System and Zoom Reach: Fixed Superzoom vs Versatile Interchangeables

If zoom reach is your priority, the Samsung HZ30W shines with its built-in 24-360mm (15x) zoom lens at a compact size - offering great flexibility without swapping gear. Its maximum aperture of F3.2 to F5.8 isn’t bright, limiting low-light and depth of field control, but it’s adequate for day-to-day shooting.

The Sony NEX-3 has no lens included with body only (specs blank on focal length), but the E-mount ecosystem (already 121 lenses available by mid-2010) radically expands creative scope - from fast primes for portraits and macro lenses to super-zooms and specialized glass. The 1.5x crop factor must be considered; a 50mm lens behaves like a 75mm full-frame equivalent, etc.

While the HZ30W offers instant all-in-one flexibility, the NEX-3’s system approach is indispensable for photographers serious about optical quality and artistic control. You can start small and grow, matching your lens choice to every genre, whereas the Samsung’s fixed lens constrains your style.

Image Stabilization and Low-Light Capabilities

The Samsung includes optical image stabilization (OIS), an essential feature for steady shots at long zoom reaches and low shutter speeds. This assists handheld shooting comfortably up to around 360mm equivalent. However, the small sensor still restricts ISO sensitivity and noise control - so stabilization compensates only so much.

The Sony NEX-3 does not incorporate in-body image stabilization. Instead, stabilization depends on lenses with OSS (Optical SteadyShot), available in many E-mount lenses. The larger sensor permits much higher native ISOs (up to 12800) with usable noise performance in low light, reducing the absolute need for stabilization in many scenarios.

For travel and urban shooters needing versatility, the Samsung’s OIS is convenient; for enthusiasts who will invest in stabilized lenses or shoot with ambient light, the NEX-3’s sensor and lens combination is more effective.

Video Recording Features: Basic HD in Both

Neither camera pushes boundaries in video. Both shoot up to 1280x720 (720p) HD video at 30fps, with the Samsung using H.264 and the Sony MPEG-4 codecs. No 1080p or higher resolutions, no microphone input or headphone output - limitations typical of their era and class.

The NEX-3’s continuous autofocus and face detection lend it an edge for casual video, offering smoother focus transitions. The Samsung’s optical zoom can be adjusted during recording but AF can hunt noticeably, making it less suitable for dynamic video work.

In summary, if video is a secondary concern or you intend casual clips, both suffice. But videographers should look elsewhere.

Battery Life, Storage, and Connectivity

The Samsung HZ30W uses an SLB-11A battery (capacity unspecified) with unknown official shot counts but typical compact superzooms dot the 200-shot range. Storage is limited to single SD/SDHC/SDXC cards, standard for this class. No wireless features are present.

Meanwhile, the Sony NEX-3 packs a much more robust 330-shot battery life (CIPA rating) using NP-FW50, typical for mirrorless cameras and sufficient for day trips. It accepts SD and Sony Memory Stick cards. Wireless connectivity is limited but features Eye-Fi card support, easing image transfer via compatible SD cards.

Both have HDMI and USB 2.0 ports for tethered workflows - a meaningful difference for professionals or enthusiasts wanting easy offload and external display options.

Build Quality and Weather Resistance: Entry-Level Plastics with No Sealing

Neither camera boasts environmental sealing, weatherproofing, or ruggedized construction. The Samsung’s plastic shell feels somewhat less refined, whereas the Sony’s design is sturdier yet still plastic-heavy.

Neither is ideal for challenging outdoor conditions without protective accessories. But both are fine for casual outdoors use in fair weather.
