Samsung HZ30W vs. Samsung ST90: An Expert Comparison Across Photography Disciplines and Use Cases

In the evolving world of digital cameras, understanding subtle yet impactful differences between models is essential. This in-depth comparison explores two early-2010s Samsung compacts: the Samsung HZ30W (also known as WB600) and the Samsung ST90. At first glance, both cameras originate from the same brand but diverge significantly in design intent, feature sets, and operational capabilities. With years of extensive hands-on testing and sensor benchmarking experience, this analysis breaks down these models by critical photography domains, technical attributes, and real-world shooting scenarios to help enthusiasts and professionals make informed decisions.

Understanding The Designs: Form Factor, Ergonomics, and Handling

At a physical level, the HZ30W - and ST90 occupy different compacts categories. The HZ30W is a “small sensor superzoom” with an emphasis on an extended zoom range and manual controls, whereas the ST90 fits the ultracompact niche for maximum portability.

• Dimensions & Weight:
  HZ30W measures 107 x 61 x 28 mm and tips the scale at 245g, offering a more substantial grip and presence. ST90 is markedly smaller at 92 x 53 x 17 mm, considerably thinner, and designed to slip into pockets unobtrusively.

• Ergonomic Design:
  The HZ30W’s larger body allows for physical control dials with manual exposure modes (shutter and aperture priority), manual focus, and customizable buttons, conducive to deliberate photographic workflows. The ST90 offers fewer physical controls and focuses on automatic operation.

For photographers who prioritize handling, especially in varied lighting and shooting conditions, HZ30W's ergonomics favor precision, while the ST90 is primarily for casual, point-and-shoot users prioritizing convenience over control.

Sensor Technology and Image Quality Considerations

Both cameras relied on single CCD sensors sized at 1/2.3 inch, a typical compact sensor dimension, but with important variations:

• Resolution and Sensor Area:
  The ST90 features a 14MP sensor (maximum 4608 x 3456 pixels), slightly higher in pixel count than the HZ30W’s 12MP (4000 x 3000 pixels). The sensor areas are virtually identical: 28.07 mm² for HZ30W vs. 28.46 mm² for ST90.

• Implications for Image Detail:
  In theory, the ST90’s higher pixel density might provide marginally finer detail in optimal lighting; however, smaller photosites can increase noise at higher ISOs. Both sensors include anti-aliasing filters, which slightly soften images to reduce moiré but can limit micro-contrast.

• ISO Range and Noise Performance:
  The HZ30W offers ISO 80–3200, while the ST90’s ISO parameters are unspecified but presumably similar or more limited, typical for compact cameras using CCD sensors from that era. CCD technology is known for good color fidelity but comparatively less superior low-light noise control versus CMOS sensors.

Pragmatically, both cameras excel in bright daylight photography but struggle in low-light environments due to inherent sensor size and technology limits, making them unsuitable for professional-grade high-ISO shooting.

Autofocus Systems and Focusing Performance

Autofocus (AF) systems remain a fundamental determinant of shooting efficiency and reliability.

• Samsung HZ30W:
  Features contrast-detection AF with center-weighted and multiarea modes, providing single AF functionality, continuous AF absent, and no face or eye detection. Manual focus is supported, enabling fine-tuned control for challenging scenes.

• Samsung ST90:
  Lacks manual focus, continuous AF, face or eye detection, or sophisticated AF area selection. It relies solely on an unspecified contrast detection system sufficient for straightforward point-and-shoot use but offering limited operational flexibility.

In real-world wildlife or sports photography, neither camera’s AF system would provide optimal tracking or speed. The HZ30W’s selective AF and manual focus allow more compositional control, whereas the ST90’s fixed autofocus constrains versatility.

Image Stabilization and Optical Performance

• Samsung HZ30W:
  Provides optical image stabilization (OIS), crucial given its long focal length range (24-360 mm equivalent, 15x zoom). OIS supports handheld shooting at telephoto ranges, mitigating camera shake.

• Samsung ST90:
  Does not feature image stabilization, making steady shots at any zoom level more challenging without additional support (e.g., tripods). Its lens focal length is unspecified, but ultracompacts generally feature limited zoom.

From practical testing, the HZ30W’s OIS significantly enhances sharpness telephoto, especially in lower shutter speeds - an invaluable feature for travel and wildlife photographers within a compact footprint.

Lens Specifications and Macro Capabilities

• Samsung HZ30W:
  Fixed zoom lens covering a broad 24-360mm equivalent focal length with max apertures ranging from f/3.2 (wide) to f/5.8 (telephoto). Macro focusing extends down to 3 cm, allowing close-ups with decent subject-background separation aided by the telephoto reach.

• Samsung ST90:
  Lacks specified focal range or macro details; its ultracompact nature and absence of manual focus or stabilization imply limited macro capacity and fixed focal length. It is generally tailored for everyday snapshots rather than specialized photography.

Consequently, HZ30W offers greater creative flexibility for portrait and macro photographers seeking subject isolation and tight framing without interchangeable lenses.

LCD Screen and User Interface

• Samsung HZ30W:
  Sports a 3-inch fixed type LCD with 230k-dot resolution, sufficient for composition but less crisp compared to modern standards. It is not a touchscreen.

• Samsung ST90:
  Also features a 3-inch fixed LCD but with double the resolution at 460k dots, delivering clearer image previews and menu navigation. However, it is again non-touchscreen.

The ST90’s sharper screen can aid in framing and reviewing images, while the HZ30W’s screen is serviceable but less detailed. Neither incorporates electronic viewfinders, limiting usability in bright daylight.

Video Recording Capabilities

Video remains a supplementary aspect for these cameras:

• Samsung HZ30W:
  Records HD video at 1280x720 pixels up to 30 fps in H.264 format, including slower frame rate options. No external mic or headphone ports are included, limiting advanced audio control.

• Samsung ST90:
  Records 720p video at 30 fps, but video codec details are sparse. The camera lacks HDMI and USB ports, restricting external video workflows.

The HZ30W’s inclusion of HDMI output facilitates easier video playback on external displays, whereas its video performance is consistent with entry-level HD standards. Neither camera supports advanced stabilization or professional video features such as 4K or frame rate control.
