Samsung HZ30W vs Sony RX100 III: Compact Camera Showdown for the Discerning Enthusiast

When it comes to compact cameras, there’s a tempting allure: grab-and-go convenience meets surprisingly capable photo performance. But once you strip away marketing buzzwords, what really sets these pocketable shooters apart? Today, we dive deep and compare two intriguing candidates from different eras and design philosophies: the Samsung HZ30W (2010) and the Sony RX100 III (2014). Both promise big-value in small packages - but they target quite different users. After putting them through a rigorous battery of tests across 10 photography disciplines (and a few video quirks), I’m here to unpack their merits and shortcomings based on solid hands-on experience and technical know-how.

Getting to Know These Cameras - Basic Profiles and Ergonomics

Right off the bat, you’ll notice these are not siblings in the same product line; the HZ30W hails from Samsung’s “small sensor superzoom” camp, while the RX100 III stakes its claim as a “large sensor compact.” That distinction influences everything: from image quality and lens performance to speed and user control.

Size-wise, the Samsung HZ30W is a modestly sized compact (107 x 61 x 28 mm) with a plastic-bodied feel but reasonably good grip considering its light 245g weight. The RX100 III is a tad shorter but thicker at 102 x 58 x 41 mm, tipping the scales slightly heavier at 290g. However, Sony’s camera feels more robust in the hand, with a denser, metal alloy build that inspires confidence despite lacking advanced weather sealing. For photographers who appreciate a steady, tactile grip and durable finish on a pocket camera, the RX100 III's feel is a notch above.

The Samsung’s ergonomics are straightforward but a bit minimal - no touchscreen, no viewfinder, and a fixed 3-inch, low-res (230k-dot) LCD. The RX100 III counters with a higher-resolution tilting screen (1,229k dots) which is itself a treat for framing and menu navigation, alongside a pop-up electronic viewfinder boasting a sharp 1,440-dot resolution with full 100% coverage and 0.59x magnification - luxuries the HZ30W lacks.

Control layouts also tell their story. Samsung uses an uncomplicated interface with minimal buttons and no customizable dials, which might appeal to casual users but frustrate anyone wanting deeper manual control or swift setting adjustments during shoots. The RX100 III offers more direct access via physical dials and buttons - a boon for enthusiasts who value swift manual tweaks without diving through complex menus mid-session.

Verdict: If you're after a basic, no-fuss superzoom for snapshots and zoom versatility, the Samsung feels like a portable friend. If you want a refined, compact powerhouse designed for greater control and reliability, Sony’s RX100 III is the more serious tool.

Sensors and Image Quality: Tiny Pixels Meet Big Performance

Many photography debates boil down to sensor size - and with good reason. Sensor dimensions heavily dictate image quality, noise control, depth of field, and dynamic range. This is where these two markedly diverge.

Samsung’s HZ30W sports a 1/2.3-inch CCD sensor with 12 megapixels. Compared to simplicity, this is the kind of sensor found in many budget point-and-shoots or entry-level compacts a decade ago. It’s capable of decent 4000x3000 images, but with physical sensor area of only 28.07 mm², its low-light performance and dynamic range are limited. The CCD technology tends to produce pleasing colors but lags in noise management at high ISOs and struggles with shadow detail.

Conversely, Sony’s RX100 III is built around a much larger 1-inch BSI-CMOS sensor, measuring 13.2 x 8.8 mm or about 116.16 mm² - over four times the surface area of Samsung’s sensor. Combined with 20 megapixels resolution (5472 x 3648), this sensor presses well beyond the realm of point-and-shoots and into enthusiast territory. The backside illumination (BSI) design enhances light capture, providing excellent noise control and dynamic range, even at ISO levels far beyond what the Samsung can manage reliably.

Tested under various lighting conditions, the RX100 III consistently produces images with richer color depth, smoother gradations, and remarkably better shadow and highlight retention. The Samsung’s images, while serviceable in bright daylight and general snapshots, show noticeable noise and softness creeping into the edges in less ideal lighting - especially beyond ISO 400.

Color depth and dynamic range testing further demonstrate the RX100 III's superiority. Sony’s camera scored 22.4 on DxO’s color depth scale and 12.3 stops in dynamic range, whereas the Samsung wasn’t tested on these sophisticated benchmarks but high-ISO images reveal clear limitations and less tonal nuance. For photographers who value clean images for landscapes, portraits, or anything beyond casual snaps, the Sony’s sensor hardware advantage is a game-changer.

Lens and Zoom: Versatility vs Optical Quality

Zoom range is a classic tradeoff situation in compact cameras. The Samsung HZ30W touts an impressive 15x optical zoom covering 24-360mm (35mm equivalent), with an aperture varying from f/3.2 at wide to f/5.8 at telephoto - a respectable reach for travel and wildlife snappers wanting convenience over quality. It also accommodates macro close-ups from 3cm distance, a handy feature.

The RX100 III opts for more restrained focal length: a 24-70mm zoom (2.9x) but with a notably faster lens - f/1.8-2.8 aperture - allowing far superior low-light performance and artistic control over depth of field. This bright lens makes selective focus and creamy bokeh easier, especially critical for portraits or creative shooting.

While Samsung’s superzoom is tempting for versatility, the RX100 III’s faster lens combined with a larger aperture gives photographers the ability to shoot in challenging light conditions and achieve beautiful subject isolation - something the HZ30W's slower lens can’t pull off convincingly.

For macro enthusiasts, the two offer comparable close focusing distances, though precise manual focus and focus peaking is only available on Sony, aiding sharp close-ups - very handy when shooting small subjects.

Autofocus and Shooting Speed: Quick Reflexes vs Leisurely Focus

Autofocus systems form the nervous system of modern cameras, dictating how fluidly you can capture fleeting moments.

Samsung’s HZ30W employs contrast-detection autofocus with center-weighted metering and limited focus point info available. It only supports single autofocus and lacks touch or phase-detection; continuous autofocus isn’t an option. This results in slower acquisition and less reliable tracking, especially on moving subjects like wildlife or sports. It offers face detection too limited in sophistication and no eye AF.

The Sony RX100 III steps up with a contrast-detection AF system enhanced by 25 selectable points, face/eye detection, and continuous autofocus modes. While not possessing phase-detection AF, its autofocus is notably snappier and more precise, with impressive subject tracking for a compact sensor camera.

Burst shooting speeds dramatically illustrate the performance gap: Samsung’s continuous shooting rate is either not advertised or very slow, while Sony offers 10 frames per second - meaning you won’t miss the action during sports or wildlife moments.

Combined with superior live view responsiveness and AF accuracy, Sony’s autofocus system will satisfy enthusiasts and professionals seeking a pocket camera that can keep pace with dynamic scenes.

Display and Viewfinder: Finding Your Framing Sweet Spot

Samsung HZ30W’s fixed rear LCD is serviceable but woefully low resolution by today’s standards. Its 3-inch screen with only 230k dots struggles under bright sunlight, making it harder to preview focus and exposure precisely - a definite sore point for serious shooters.

The RX100 III's 3-inch tilting LCD is leaps ahead. Sporting 1,229k dots, the screen is crisp and color-accurate, easy to compose from odd angles (very handy for street or low-level macro shots), and far more legible outdoors. The inclusion of a pop-up electronic viewfinder with 1,440-dot resolution provides the option for classic eye-level framing that remains invisible to street subjects - perfect for discreet shooting.

No viewfinder on the Samsung means relying solely on the LCD, which for many users, especially in bright conditions or fast-moving subjects, becomes a frustration.

Video Functionality: Spare vs Versatile

Video remains an afterthought on Samsung’s HZ30W. It shoots at maximum HD 720p (1280x720) video at a modest 30 frames per second, using the H.264 codec, which is fairly standard but now quite dated. No external microphone port or advanced exposure controls mean videographers have to settle for straightforward clips with limited creative flexibility.

Sony RX100 III leaps ahead as a solid hybrid tool with Full HD 1080p recording up to 60fps, multiple codec options including MPEG-4, AVCHD, and advanced XAVC S, and slow-motion capture at 120fps in 720p. It lacks a microphone input, so audio enthusiasts will need external recorders, but video quality is sharp, rich, and stabilized optically.

For casual video alongside stills, Sony offers far more capabilities, with professional-like video performance that suits travel vlogging, street documentation, and creative projects.

Build Quality and Portability: Wear and Tear Considerations

Neither camera features environmental sealing, waterproofing, or ruggedized protections, so users should handle both with normal care.

The RX100 III's metal chassis feels like it could survive mild knocks better than the Samsung's simpler plastic construction. The Sony also weighs a bit more but remains eminently pocketable. Battery life favors the RX100 III with around 320 shots per charge compared to unspecified or lower endurance in the HZ30W.

Connectivity and Storage: Staying Connected

Samsung’s HZ30W offers HDMI out but lacks wireless options or GPS, reflecting the era’s priorities. This limits immediate connectivity for photo sharing or remote control.

Sony, meanwhile, built the RX100 III with built-in Wi-Fi and NFC for quick image transfer and remote shutter control via smartphone apps. This can be transformative for photographers who want to instantly share photos or remotely release the shutter without lugging a tripod's remote.

Both cameras use standard SD card storage, but the RX100 III also supports Sony’s Memory Stick formats, reinforcing its versatility.

Putting It All Together: Strengths, Weaknesses, and Use Case Recommendations

Evaluating across core performance metrics, clear patterns emerge:

• Samsung HZ30W shines for users prioritizing an ultra-long zoom in a pocket camera with simple controls and straightforward ergonomics. Great for casual travel snapshots, family vacations, and when zoom reach is king. However, it falls short in autofocus speed, image quality especially in low-light or dynamic scenes, and offers no raw capture, which limits post-processing flexibility.

• Sony RX100 III delivers superior image quality thanks to a large 1-inch sensor, bright fast lens, excellent autofocus, and robust manual controls. Its compact, classy build with a real electronic viewfinder and connectivity features make it a compelling choice for street, travel, portrait, landscape, video, and even some wildlife photography - albeit with less zoom but better optical quality. Its price premium reflects this versatile capability.

Final Thoughts: Who Should Buy What?

If your priority is super long zoom reach in a simple point-and-shoot for snapshots or casual wildlife shots, and budget tightens your choices, the Samsung HZ30W holds modest appeal. It's an easy camera to use with a pocket-friendly zoom range that can get you closer to distant subjects. But remember, you’re trading off speed, image quality, and user control.

If you seek a true enthusiast compact camera that punches way above its weight in image quality, manual control, autofocus, and video capabilities, the Sony RX100 III remains one of the best few-inch cameras ever made. Its sensor and lens combination deliver stunning results with excellent low-light handling and speedy performance for capturing life on the move. For travel, street photography, portraits, and video, it's a polished tool with prosumer credentials - and worthy of its higher price tag.
