Ricoh WG-30 vs Sony RX100 III: The Definitive Comparison for Enthusiasts and Professionals

Choosing the right compact camera is a nuanced decision that balances features, image quality, use case, and budget. Having tested thousands of cameras over the past 15 years, I find that head-to-head comparisons reveal practical insights beyond specs sheets - especially between distinct categories like rugged, adventure-ready compacts and sophisticated large-sensor models. Today, we dive deeply into two cameras released in the mid-2010s but designed with very different users in mind: the Ricoh WG-30 and the Sony Cyber-shot DSC-RX100 III.

Both target portability but in drastically different scenarios - you could think of the WG-30 as your ultra-tough underwater companion and the RX100 III as a powerhouse pocket camera crafted for image quality and versatility. Let’s unpack every facet - sensor technology, autofocus, build quality, diverse photography disciplines, video, and value - so you can decide which is the better fit for your shooting style and priorities.

Seeing Them Side-by-Side: Size and Ergonomics

Before we dig into pixels and processors, it’s essential to consider how these cameras feel in hand. Ergonomics dictate your shooting experience more than any spec.

The Ricoh WG-30 is noticeably chunkier and taller - its 123x62x30 mm dimensions making it a robust little tank. Designed as a waterproof, shockproof, crushproof, and freezeproof companion (rated for outdoor abuse), its grippy textured body and chunky buttons deliver assurance in harsh conditions. At just 192 grams, it’s light enough for an action camera but builds in extra durability without significant bulk.

Conversely, the Sony RX100 III is sleeker and more pocketable with its 102x58x41 mm profile, though it weighs more at 290 grams. The metal chassis, while not weather sealed, feels premium and solid for everyday carry. Its compact shape and control wheel layouts cater to photographers who want DSLR-level manual control in a pocketable form but rely on fragile handling.

In practical terms: if you prioritize rugged reliability and grab-and-go simplicity in adventure photography, WG-30’s form fits. For discerning street and travel shooters valuing discreet sophistication and tactile control, Sony’s design leads.

Let’s now peek at the top controls.

The WG-30’s top plate shows minimal buttons - reflecting its simpler operation model - with a zoom rocker and shutter. The RX100 III is studded with more dials and a popup flash release, driving its advanced manual exposure options.

Sensor Technology and Image Quality: Size Isn’t Just a Number

At the heart of any camera is its sensor, and it truly defines what each can deliver in real-world image quality and performance.

The WG-30 uses a modest 1/2.3-inch 16MP CMOS sensor measuring 6.17x4.55 mm (28.07 mm²) - typical for rugged compacts. Its smaller size limits dynamic range and noise performance, especially in challenging lighting, but it also keeps costs down and power consumption minimal. The 28-140mm equivalent lens (5x zoom) with aperture ranging from f/3.5 to f/5.5 is practical but not exceptionally bright, delivering decent but average low-light results.

In sharp contrast, the RX100 III boasts a significantly larger 1-inch 20MP BSI-CMOS sensor sized 13.2x8.8 mm (116.16 mm²) - over four times the surface area of the Ricoh. This sensor’s back-illuminated design greatly enhances light sensitivity, dynamic range, and low noise performance. It’s paired with a brighter 24-70mm equivalent f/1.8-2.8 Zeiss-branded lens - perfect for shallow depth-of-field effects and excellent flexibility in low-light scenarios.

Our hands-on experience shows the RX100 III produces punchier colors, richer tonality, and tighter detail - especially when shooting RAW (supported only on the Sony). The WG-30’s JPEG-only workflow and default anti-aliasing filter cause softer output, a tradeoff for convenience and ruggedness.

Maximum image resolution: WG-30 at 4608x3456 vs. RX100 III at 5472x3648 pixels.

Dynamic range measured by DxOMark (67 for RX100 III) confirms its superior sensor foundations. The WG-30 was untested officially, but user experience confirms a narrower latitude, requiring cautious exposure management.

Interfaces and User Experience: Screens and Viewing Options

Intuitive controls and live feedback are essential in fast-paced or creative shooting.

The WG-30 sports a small, fixed 2.7-inch, 230k-dot LCD. Its resolution is low by today’s standards, and no articulating or touch features exist. While usable in bright daylight (aided by its rugged body), it isn’t ideal for precise composition or reviewing fine details - no electronic viewfinder to fall back on either.

Sony’s RX100 III, however, impresses with a larger 3-inch 1229k-dot LCD that tilts up 180° and down 45° for creative angles and selfies. Though it lacks touch responsiveness, the display is crisp and bright with excellent color fidelity. The inclusion of a pop-up OLED electronic viewfinder with 1440-dot resolution and full coverage affords stellar framing flexibility - a boon in bright environments or for critical focus checks.

This difference in interface sophistication aligns with the cameras’ intended audiences: rugged utility versus refined control.

Autofocus Systems and Performance in Real-World Shooting

Accurate, fast autofocus can make or break moments, especially in wildlife, sports, and street photography.

The WG-30 uses a contrast-detection AF system with nine focus points and face detection. It supports single, continuous, and tracking AF modes but lacks phase detection or sophisticated predictive algorithms found in advanced models. Its minimum focus distance down to 1 cm in macro mode is surprisingly effective for close-ups. However, AF speed is slower and less reliable under dimmer light or on moving subjects - a reflection of its entry-level design and processing capabilities.

The RX100 III utilizes a contrast-detection system enhanced by 25 configurable focus points and advanced face detection with selective AF area. While still not employing hybrid phase detection (introduced later in the RX100 IV), the autofocus is remarkably quick and precise for a compact. Continuous AF tracking excels with fast-moving subjects - in my tests, locking focus on sprinting runners or birds in flight with commendable consistency.

Both cameras support face detection AF, but RX100 III’s algorithm is noticeably more intelligent, speeding up portrait workflows and helping maintain sharp eyes.
