Selecting the right compact camera can be a nuanced decision. Between models like the Pentax Optio WG-2 and the Sony Cyber-shot DSC-S930, photographers often weigh different strengths that appeal to specific shooting scenarios and professional requirements. This in-depth comparison leverages my 15 years of extensive hands-on testing experience to dissect each model’s capabilities across multiple photography disciplines, technical parameters, and ergonomic designs.

Throughout, you will find an evidence-based evaluation paired with real-world usability analyses and practical advice for enthusiasts and professionals alike. Moreover, every aspect is oriented towards matching camera features with user intent, not marketing fluff.

Physical Dimensions and Handling: Rugged Utility vs Slim Compactness

Physical design significantly influences both ergonomics and shooting convenience, especially for travel and street photography tasks.

Pentax WG-2 adopts a robust and utilitarian build, optimized for durability under harsh conditions. This model’s environmental sealing renders it waterproof, crushproof, shockproof, dustproof, and freezeproof. Such ruggedness elevates its suitability for demanding outdoor work, including landscape, wildlife, and adventure travel photography.

Conversely, the Sony DSC-S930 embodies a smaller footprint with a more traditional compact design. The camera’s slim profile facilitates inconspicuous street shooting and quick carry, but lacks any weather sealing or shock protection - a limitation for photographers planning outdoor or rugged use.

The ergonomics of the WG-2 favor grip security thanks to its thicker body and textured surfaces, although its bulk may present fatigue during long handheld sessions. The S930’s lighter weight benefits discrete operation but sacrifices handling comfort under dynamic shooting conditions.

Sensor Technology and Image Quality: Resolution and Sensitivity Contrasts

The imaging sensor is critical to image quality, influencing resolution, noise handling, and dynamic range. Both cameras house 1/2.3" sensors of identical physical dimensions (6.17 × 4.55 mm) but differ markedly in sensor type and resolution.

The WG-2’s Backside Illuminated (BSI) CMOS sensor is a significant technological leap over the older CCD sensor in the S930, particularly in low-light performance and dynamic range. BSI CMOS architecture improves sensitivity by orienting the sensor wiring behind the photodiodes, maximizing light capture - a design critical for night, astro, and indoor shooting situations.

Further, the WG-2’s higher 16MP resolution provides greater detail potential, beneficial for cropping flexibility and landscape photography where fine texture and large prints are desired. However, keep in mind the inherent limitations imposed by the sensor size itself; neither model will rival APS-C or full-frame cameras for ultimate image fidelity.

The S930’s lower 10MP resolution and CCD technology result in comparatively less dynamic range and higher noise at elevated ISOs, restricting its use for critical low-light or high-contrast scenes. Both employ an anti-aliasing filter, reducing moiré but slightly softening detail.

Lens and Zoom Capabilities: Versatility versus Reach

Lens specifications reinforce or limit a camera’s practical use in various genres.

The WG-2’s wider zoom range is a marked advantage, providing wide-angle to moderate telephoto coverage (28–140 mm equivalent). This breadth suits everything from landscapes and architecture to wildlife and casual portraits. Its close focusing distance of 1 cm enables detailed macro capture, advantageous for insect or flower photographers.

In contrast, the Sony S930 offers a narrower 38–108 mm zoom but benefits from a brighter aperture at the wide end (f/2.9 vs. f/3.5) and optical image stabilization to reduce camera shake. The stabilization is valuable for handheld shooting, notably in low light or at the telephoto end, although the lens is less versatile in framing scope. Its minimum macro distance at 5 cm is respectable but limits extreme close-up detail.

Neither camera supports interchangeable lenses or advanced lens control modes such as aperture priority, which constrains creative depth-of-field manipulation.

Autofocus System and Performance: Precision and Speed in Different Contexts

Accurate and responsive autofocus (AF) mechanisms directly affect success in action, portrait, and wildlife photography.

The WG-2 features a 9-point contrast-detection AF system with face detection and a rudimentary AF tracking mode. During my field testing, the WG-2’s face detection proved reliable under good lighting, enhancing portrait accuracy, especially with moving subjects. However, its AF speed is modest, typical of compact point-and-shoot units, which limits performance in fast sports or wildlife action.

Sony’s S930 offers a similar 9-point contrast-detection AF but lacks face detection and has no AF tracking functionality. This means autofocus can be slower to lock on human subjects, plus less reliable in unpredictable scenarios. For static subjects or casual snapshots, the S930 tracks satisfactorily.

Neither camera supports phase detection AF or eye-detection AF, limiting precision autofocus performance against modern mirrorless or DSLR standards.

LCD Display, Viewfinder, and User Interface: Information Visibility and Control Access

Intuitive interface design and viewing options are essential for workflow efficiency.

The WG-2’s 3.0-inch LCD with 460k dot resolution delivers significantly sharper and more detailed image preview and menu interface than the small, low-resolution display on the S930. This difference was palpable in bright daylight shooting, where the S930’s screen became challenging to interpret.

Both cameras lack optical or electronic viewfinders, relying exclusively on rear screen framing. The absence of a viewfinder can hamper outdoor compositional precision, especially under strong sunlight.

Regarding user controls, both cameras present fixed button layouts with no touchscreen capability. Neither offers any illuminated buttons, affecting usability in low-light environments. The WG-2’s buttons feel more robust and better spaced, correlating with its larger size.

Video Recording Capabilities: Resolution and Frame Rate for Clips

Video features have become standard, but their sophistication still varies.

The WG-2 offers full HD 1080p video at 30 fps plus HD 720p at 60 fps. It supports efficient H.264 compression, resulting in manageable file sizes and good playback compatibility. These capabilities support casual videography and travel documentation, albeit without professional audio input.

In contrast, the S930 limits video to a very low 320 × 240 pixel resolution with Motion JPEG - an outdated and inefficient format producing large files with poor visual quality. This restricts its use to basic novelty video without practical value for serious recording.

Neither camera includes external microphone or headphone jacks, limiting audio control.

Battery, Storage, and Connectivity: Power Management and Workflow Integration

Efficient power usage combined with flexible storage options affects on-location productivity.

The WG-2's dedicated rechargeable lithium-ion battery offers respectable endurance for a compact camera in its class, with about 260 frames per charge measured under standard CIPA conditions. This supports prolonged outdoor shooting without frequent battery swaps.

The S930 uses widely available AA batteries, facilitating easy field replacement at the expense of more frequent changes and variable performance depending on battery brand. Official battery life figures are not published, but practical tests suggest comparable endurance under typical use.

Storage options on the WG-2 are more flexible and modern, supporting SD standards including SDXC for large capacity cards. The S930’s reliance on proprietary Sony Memory Stick Duo cards reduces compatibility and increases cost. Availability may also be limited in certain regions.

Connectivity advantages clearly favor the WG-2, which supports Eye-Fi wireless SD cards enabling image transfer without cables, and offers a USB 2.0 port plus HDMI output for HD video preview. The S930 lacks all wireless and conventional wired connectivity options.
